Five Tour Guides in Benxi Water Cave, Liaoning Province (1)
Welcome to Benxi Water Cave!
Benxi Water Cave is located in Benxi County, 35 kilometers away from Taizi River in the eastern mountainous area of Benxi City. This is a large limestone flushing cave, which was formed millions of years ago in the late third century. The scenery here is beautiful, famous for its strange caves, strange rocks and still water.
The water tunnel consists of three holes. The main cave is a 5800-meter-long underground flushing cave, and it is also the longest underground flushing cave found in the world at present. Now it has developed to 2800 meters, known as? Wonders of the world? . The auxiliary cave is a dry cave, and now a paleontological exhibition hall has been established by using natural caves, which reproduces the evolution process of paleontology for hundreds of millions of years. In addition, there is a drainage hole.
Nowadays, the water cave, together with the surrounding hot springs, Miaohou Mountain, Guanshanmen, tanggou and Tiesha Mountain, has formed a national key scenic spot and a national 4A-level tourist area.
Come on, now let's enjoy the strange water cave scenery together!
The entrance of the water tunnel faces south. What is inscribed on it? Benxi Water Cave? The four characters are 1983, which was inscribed by Comrade Bo Yibo when he visited Benxi.
This is the site of ancient culture. Archaeologists unearthed a large number of stone tools, ground pottery and other cultural relics here, indicating that the ancestors of Liaodong lived and multiplied here as early as 6,543,800 years ago.
The water cave hall, also known as the welcome living room, can accommodate more than a thousand people. The welcoming hall is connected with the three holes. There is a dry hole on the right and a drainage hole on the left. Directly ahead is a puddle.
This is an oval dry cave. The Palaeontological Palace was built here, showing the evolution process of paleontology.
Please come with me to visit the water cave by boat. The water cave, also known as the "Nine Curves Galaxy", covers an area of 36,000 square meters. The underground river in the cave is inexhaustible in all seasons, with an average water depth of 1.5 meters and the deepest point of 7 meters. It can be said that visiting Benxi Water Cave is like "boating in the ancient cave". According to its landscape form, the water tunnel can be divided into "two gates, three Gorges, seven palaces and nine bends", with more than 0/00 landscapes. All the scenery in the cave is naturally formed. Look, that's the "Lotus Lantern", and in front of it is the "Furong Gorge". Lotus, also known as hibiscus, is deeply loved by our people, and is also known as the six famous flowers in history with plum, orchid, chrysanthemum, peony and peony. The lotus should have bloomed upward, but it is upside down here.
Further on, it is the "Guanghan Palace". That is, the moon palace where Chang 'e lives.
Out of the Guanghan Palace, it is the "Double Sword Gorge". Stalactites are like swords, hanging high on the ground. Visiting here is really "a boat swims in the water, and a man wears a sword."
After crossing the Shuangjian Gorge, it is the first gate of the "Nine Curves of the Galaxy"-"Jianmenguan". After passing through the sword gate, the cave body suddenly became tall and spacious, which is the strangest and most beautiful place in Jiuge Yinhe Cave.
Now enter the second Humen of "Jiuqu Yinhe". Look, that stone is really a tiger that always looks fierce.
Enter the "Jade Elephant Gorge" ahead. What is this? Nine songs galaxy? The longest section, about 700 meters.
What you see now? Leaning tower? The slope exceeds the leaning tower of Pisa by 30? It is the best in the world.
Dear friends, what we are seeing now is the "world of ice and snow"-the Arctic Palace. The Arctic Palace is the largest palace in Jiuge Galaxy.
Beyond the snow-capped mountains, in front of us is the Jade Palace, the sixth courtyard of the Nine Curves Galaxy. The stalagmites on the island in the river look like a slim girl!
What we are seeing now is the last palace of the Jiuqu galaxy-"Yolanda Palace". This is the end of the developed part of Benxi water tunnel, from which the flowing water of underground river gushes out.
Dear friends, we have reached the end of the development section, and the huge stone wall ahead makes it impossible for us to move forward. However, the water hole is not at the end, and it is more than 3000 meters away from Discovery. Therefore, the future development prospect of water tunnel is very broad.
Friends appreciate the wonders of this water cave. You may ask: How did such a big cave come into being? Where does the underground river come from?
In fact, the formation of water tunnels has gone through a long historical process. 450 million years ago, Benxi was still a shallow sea with a lot of limestone deposited. After five violent geological tectonic movements, especially the Yanshan movement 70 million years ago, Benxi not only changed from shallow sea to land, but also produced large and small cracks in sedimentary limestone. Water containing carbon dioxide flows along the cracks, constantly dissolving limestone into calcium bicarbonate, making the cracks bigger and becoming caves, and finally forming today's Benxi water cave over time.
Friends, we are out of the puddle now. Outside the cave, this is cherry orchard and Mulan Garden. Virgin flower is the city flower of Benxi city. It's white, huge and fragrant. Flowers bloom twice a year in June and September, which is a treasure among flowers.
Welcome to Benxi Water Cave again!

Hello, tourists, I'm Liu Jinda, the tour guide. We are going to visit Benxi Water Cave. There are many strange stones in Benxi Water Cave. Today's grotesque stones were formed because of years of running water. So please consciously protect its hygiene when visiting.
The strange stones in Benxi Water Cave are very strange, and the most famous one is the Tiger Mouth Stone. Due to years of bacterial corrosion and running water erosion, today's boulder is like a tiger's mouth. The tiger's mouth stone looks extraordinary. At first glance, it seems that there really is a big tiger coming at you with its mouth open.
Almost as famous as the tiger's mouth stone is the giant Buddha's lecture. That boulder was corroded by bacteria for a long time and washed away by running water, forming today's "Giant Buddha". The monks and Buddhists who listen to the scriptures below are all caused by the constant erosion of running water over the years. Therefore, monks and buddhas who listen to the scriptures are not so particular.
There are many strange stones and fossils in Benxi Water Cave. The most prominent fossil is that of a carnivorous dinosaur. Big head, two small claws and two thick thighs vividly reproduce the life scene of carnivorous dinosaurs at that time.
There are many strange stones and fossils in Benxi Water Cave, as well as many ancient vessels. That is, daily necessities. Although these objects are small, they let me see the situation in the emperor's time.
There are many strange stones and fossils in Benxi Water Cave, and there are many instruments used in ancient times. It's really "the third watch"! Now, please browse slowly!

Benxi Water Cave is the original "Jiuqu Yinhe Cave". It is a large underground cave with a total length of 5 kilometers. At present, the developed tourist cave is 24.38.4 meters long, with an area of 45,000 square meters and a volume of 390,000 cubic meters. The cave is large in scale and has various karst landscapes, including more than 100 places including Seven Palaces, Three Gorges, Two Gates and Nine Curves. The underground river flows smoothly and continuously, just like entering a fairyland.
Benxi Water Cave is one of the longest water sightseeing caves in the world. 1994 the State Council has been approved as a national key scenic spot. Visiting Benxi Water Cave can not only appreciate the magical beauty created by nature, but also gain a lot of knowledge about cave science.
Cave, also known as cave.
The word "karst" comes from the karst plateau in Yugoslavia. Because of the peculiar landform there, caves were formed in limestone, which attracted the attention of scientists. Since then, all beautiful phenomena have been called "karst". The science that studies this object is called "Karst and Caveology".
Karst caves are formed by the long-term dissolution of water in soluble rocks, especially limestone and dolomite of carbonate rocks.
The water in nature is not pure water but contains carbon dioxide. When water containing carbon dioxide meets limestone, it will be carbonated when it flows in the cracks of limestone, resulting in calcium bicarbonate. Because calcium bicarbonate is soluble in water, it will be carried away by water. Over time, cracks will dissolve into caves.
The longest karst cave in the world is the Mamov Cave System in Kentucky, USA. This cave was measured from 1820, and it took 180 years to find that its length was 550 kilometers.
The longest karst cave in China is Tenglong Cave in Lichuan City, Hubei Province, with a length of 39.5 kilometers.
Because of the peculiar landscape of karst caves, it has become an extremely important tourist resource in the world. In China, more than 200 karst caves have been developed and built into tourist caves for tourists to visit. Among them, Yaolin Cave in Zhejiang, Jiguan Cave in Henan, Panlong Cave in Guangdong, Furong Cave in Sichuan, Zhijin Cave in Guizhou, Yan Guan Cave in Guangxi, Shihua Cave in Beijing and Benxi Water Cave in Liaoning all introduced cave scientific research at different stages in the development and construction process, which improved the scientific taste of tourist caves.
Dear friend, you may have traveled all over the motherland and visited many famous tourist caves. Take a look at Benxi Water Cave today, and you will feel that Benxi Water Cave is still very beautiful. Each tourist cave has its own unique and exquisite landscape, and the nine-curved galaxy in the water cave is the essence of its exquisite landscape.
The underground river twists and turns all year round, with a daily flow of 50 million cubic meters. Where did this water come from? Through tracer test and isotope hydrology research, it is confirmed that its water source has three parts: one is direct supply from Tanghe River; Second, the karst water supply of Ordovician limestone aquifer under the overburden of Tanghe River bed; Third, karst water supply is distributed in the Cambrian and Ordovician limestone aquifers on the west bank of the water tunnel. After these three parts of water flow into the underground river, they are discharged into the Taizi River from Yinbo Cave (East Branch Cave) and Panlong Cave (West Branch Cave-Undercurrent Cave) respectively.
Jiuqu Yinhe is the downstream section of the underground river, that is, the length from the cave to the source is 2320m, the average water depth is 2m, the deepest part is 7m, and the water temperature is kept at 7- 12℃. According to the results of brief analysis and total analysis of water quality, it is confirmed that the water quality is high-quality drinking water.
Professor Zhu, President of Geological Society of China Cave Research Association, visited the water tunnel in early 1996. He said that all the underground rivers he has seen at home and abroad have sand and gravel deposits, but there are no traces of sand and gravel in the underground rivers. There is only one gray silty clay deposit! He believes that there is no gravel deposition in the underground river bed, which is one of the mysteries of Benxi water tunnel. He never understood it, which aroused great interest and special concern. After the research results came out, he learned that there were three reasons:
First, there is no large water inlet in the upstream section. If the recharge of Tanghe River is of "concentrated inflow" type, there must be large inflow caves and large inflow holes in the upstream section. There will also be sand deposits in the downstream part of the water tunnel. Because there are only silty clay sediments in the downstream reach, it shows that there will be no large inflow holes buried by alluvial materials in the riverbed and shore of Tanghe recharge area. Secondly, as a karst underground river, the development of water tunnel is disturbed and blocked by igneous rock-dike rock in limestone aquifer, just like a sieve built by high wall dike, and sand is not allowed to pass through. Thirdly, the hydraulic gradient of underground river is extremely slow, only 1.5%, and the flow velocity is very low. Sand and gravel cannot be transported to the downstream part of the underground river.
The continuous underground tunnel is the upper reaches of the underground river, and the length from the source tunnel to the infiltration point of Tanghe River is about 3Km.
Dear friends! When you take a cruise to a completely unfamiliar underground tunnel, you will be intoxicated by the fabulous scenery.
Now I will introduce the second mystery of Benxi Water Cave to my friends. This is the question raised by Professor Zhu, the aforementioned president of the Cave Research Association, when he visited the water tunnel in early 1996. "Why is the size of the water tunnel entrance so big? This is also the difference between underground caves at home and abroad that he saw. Generally speaking, all underground river caves have large inlets and small outlets, but the "Benxi Water Cave" has an invisible inlet and a large outlet, which is of course a mystery.
After 1996' s scientific research on Benxi water tunnel, this problem has also been satisfactorily explained. It turns out that the hole you see now is not the original outlet hole, but a water hole "eroded laterally" due to the lateral erosion of the Taizi River, which is generally about 800m long. Because the Taizi River belongs to the ancient upper-level river, and its plane shape is serpentine, its scouring ability is particularly strong, and it is fully capable of "eating" the 800m water tunnel. Under the Yandan Pavilion, about 800 meters northwest of the water tunnel, there is a cave submerged by the Taizi River. This underwater cave should be connected with the water tunnel. Because the side erosion of the Taizi River ate this section, the water tunnel became a decapitated hole. Therefore, the water hole is not the original hole, but the middle part of the hole, so the hole is very large, up to 5.75m m.
According to the research results of 1996, it can be known that the underground river in Shuidong is mainly replenished by surface water and Tanghe River, which belongs to the type of "lateral entry" underground river. However, the underground rivers with lateral input in southern China are all concentrated inflow of surface water, that is, point-like irrigation and recharge to the aquifer. Therefore, there is an extremely important "inflow cave" development, that is, there is a large water inlet. Although the underground river of Benxi water tunnel is replenished by Tanghe River, it is not a centralized inflow type, but a decentralized infiltration type, so there is no important "inflow tunnel" development and no large water tunnel entrance. This special phenomenon of Benxi water tunnel adds a new deepening model "Benxi water tunnel model" to the theory of "evolution of underground river cave development system", that is, "decentralized infiltration type with lateral input"
The formation of karst caves can be divided into three stages, namely, early diving cave stage, middle groundwater level cave stage, semi-filled cave stage and late early cave (also known as fossil cave) completely separated from groundwater level stage.
Benxi water tunnel is in the middle stage, that is, the development stage of groundwater level tunnel (semi-filling). The main cave on the west side of the cave has entered the late fossil cave stage, while the Yin Bo cave on the east side of the cave is still in the early water-filled cave development stage.
The initial stage of water tunnel development was in the early Middle Pleistocene, 400,000-500,000 years ago. After the seepage flow of Tanghe River enters the Ordovician limestone aquifer distributed in a belt between Tanghe River and Taizi River, there is a thick Carboniferous-Permian sandstone in the downstream direction, which is an impermeable layer with concentrated karst water. Rock seepage under the condition of fissure undercurrent should be mainly dissolution. At this time, the water tunnel was completely filled with water, which lasted until the middle of the Middle Pleistocene about 300,000 years ago, forming the prototype of the water tunnel. After the tunnel was completely filled with water, the tunnel continued to expand, especially the Taizi River continued to cut down, and the drainage base surface continued to shrink. Coupled with the influence of paleoclimate, the water tunnel entered the stage of "underground water level cave" in a semi-filled state about 200,000-300,000 years ago, forming an underground river. After the local Xiahe tunnel was completely or seasonally out of the water-filled state, it collapsed in the area with gentle strata, weak lithology and strong crushing mechanism, which made the tunnel space increase rapidly, and the height of the tunnel top could reach 32m, which was never reached by the aquifer groundwater level. Source:
In addition, about 200,000-250,000 years ago, the water flowing into the ground from surface water began to move on the roof and wall of the cave, thus producing the oldest secondary biochemical deposits, mainly stalactites.
About12-140,000 years ago, the main tunnel for long-term drainage was separated from the water flow and became a dry tunnel. Today's dry tunnel has developed into a new drainage outlet, during which a layer of silty clay alluvium with a thickness of 6-7m is formed, and the lower part of the tunnel is blocked.
In the middle and late Late Pleistocene, driven by the continuous decline of the water level of Taizi River, Yinbo Cave on the east side of the water tunnel became a new drainage outlet, and the dry tunnel on the west side became a dry tunnel, which no longer drained.
Since Holocene, an underground undercurrent has been formed in the dry cave on the west side of the entrance of the cave, and it is directly discharged in the form of spring water on the eroded bank of Taizi River.
In recent ten thousand years, the secondary chemical deposition of water caves has formed many stalactites, calcium plates and wall-flow stones in the relatively favorable areas of cave infiltration.
The Age of Water Cave
There are many theories or speculations about the formation age of water tunnels:
First, the formation age of water caves is about several hundred million years;
Second, the formation age of water caves is about tens of millions of years;
Third, the formation age of water tunnels is about several million years;
Fourthly, there are different speculations about the age of the formation of water caves about hundreds of millions of years.
In fact, the formation age of water caves is not that long. According to the scientific research results of Benxi Water Cave 1996, it has been accurately told that the water cave began to develop in the early and middle period of the Quaternary Middle Pleistocene, 400,000-500,000 years ago, and the prototype of the water cave was formed through fissure water filling and tunnel expansion.
In the late Middle Pleistocene between 200,000 and 250,000 years ago, an underground river like today was formed.
After visiting the water tunnel, you must want to know how the water tunnel was formed. Now let me briefly introduce the cause of Benxi water tunnel:
According to the latest authoritative research results of 1996, there are three basic advantages in the formation of water tunnels: First, the water tunnels are developed in the limestone of Majiagou Formation of Lower Ordovician, which is a soluble rock stratum and distributed in the inter-river zone between Taizi River and Tanghe River in a strip shape. Secondly, faults and common fractures are particularly developed here, and there are four groups of fault structures: east-west, north-south, northwest and northeast. Among them, the east-west fault F 1 almost coincides with the extension direction of the water tunnel. The fracture structure destroys the integrity of the rock and is also the channel for groundwater to migrate in it. Thirdly, the water flowing in limestone cracks is supplied by Tanghe River, which has strong dissolving ability.
Due to the coexistence of the above conditions in the water tunnel area, the Tanghe River flows in the limestone layer, and after hundreds of thousands of years of dissolution and collapse, a large underground river cave in Benxi Water Tunnel is finally formed.
Secondary chemical deposition
When the cave rises under the influence of neotectonic movement and is completely or partially separated from the groundwater level, it will accept the role of surface seepage. Its seepage water undergoes carbonation reaction during limestone fracture migration. The chemical composition of limestone is the result of the reaction between calcium carbonate and water containing carbon dioxide to produce calcium bicarbonate. Because calcium bicarbonate is soluble in water, it will continue to penetrate downward with the oozing water. In this way, the cracks are constantly dissolving and expanding. If this kind of water containing calcium bicarbonate (also called karst water) seeps from the cracks on the top or side wall of the cave, due to the change of physical and chemical conditions, part of its water evaporates, and as a result, calcium carbonate crystals are formed on the top or side wall, which is secondary chemical deposition.
Stalactite-like or conical secondary chemical deposits that grow downward from the top of the cave are called "stalactites", and bamboo shoots-like secondary chemical deposits that grow downward from the ground are called stalagmites. Stalactites and stalagmites connected from top to bottom are called stone pillars. The curtain-like shape formed on the side wall is called a stone curtain.
The types of secondary chemical deposits in Shuidong are relatively simple. But in a sense, it has a special position and unique characteristics.
Various stalactites, stalagmites, stone pillars, stone curtains, stone flags, stone shields, stone dams, calcium slabs and stone flowers formed on the ceilings, cave walls and platforms on both sides of the river bank.
Some are dripping stones and flowing stones formed by gravity water deposition, and some are formed by non-gravity water deposition.
1, Goose Tube: This is the original form of stalactite, which belongs to dripping stone. It is called straw stalactite abroad, and its diameter is the same as that of water drops.
2. Shidun: It is named because it is a disc-shaped shield slate. It is formed by a special kind of broken water flow.
3. Stalagmite: It is formed by dripping water, hence the name of bamboo shoot.
4. Stone pillar: It is named after stalactites and stalagmites which are connected in columns from top to bottom.
5. Leaning Tower: This is an askew stalagmite. This stalagmite originally stood upright on the platform of the shore soil layer. Because the underground river eroded the soil layer, the platform collapsed and the stalagmites also tilted. According to the measurement, this stalagmite is 3.5m high and its growth age is between 79,700 and 27,900 years. After 5 1.800 years, the growth rate is 6.76cm every four years.
6. Stalactite hanging stone pillar: It turned out to be a stone pillar, which stood on the earthen platform on the shore. Later, the soil was washed away by the underground river, and the stone pillars hung on the top of the cave.
7. Stone curtain: The stone curtain on the cave wall is named after the mantle-like deposit formed by continuous sheet-like running water along the crack of the cave wall.
8. Stone Waterfall: It is named after the waterfall sediment formed by continuous sheet-like running water.
9. Hanging stone tray: the chassis is a horizontal cover plate, the center is a young goose tube, and the edge is a skirt-shaped flowing stone or stalactite. They used to be small stone pillars, standing on the earth platform on the shore, and their chassis covered the soil on the table. Later, it was named after the soil layer on its base was washed away by the underground river and a small stone pillar with a chassis was hung.
10, Arctic Palace: It is the largest temple-like tunnel in the cave, with a height of 32m and a width of 50m, covering an area of 3,768.75m2 ... Such a magnificent tunnel is mainly due to the massive collapse of the rock stratum at the top of the tunnel, which increases the space of the tunnel.
1 1 and "Kunlun Xue Ying", also known as "Daxue Mountain", are the largest lined-up stalagmites in water caves, and their formation is mainly influenced by dike rocks.
Magma deep in the earth's crust invades the cracks in the limestone formation of Majiagou Formation, forming a water-resisting layer, which will hinder the development of water tunnels and control their extension position.
The dark brown band at the top of the cave is a dike, which is distributed in the east-west direction. The underground river was blocked because the dam was watertight. Crossing the dam requires more energy, which will cause greater damage to the rocks around the dam and cause large-scale collapse, which will make the collapsed rocks spread linearly in the east-west direction. Later, due to the concentrated infiltration of water in vadose zone along the boundary between limestone and dike rocks, calcium flakes were formed on their rocks, so the big bamboo shoots were arranged along the boundary line.
12, Jade Elephant Playing in Water, Taibai Magic Pen, Tiansheng Bridge ......
The oldest stalactite in the water cave is the stalagmite on the high platform on the right bank of the Jade Palace, which is about 18m above the water surface. Only145,000 years, less than "Long live".
cavern creatures
There are generally three kinds of animals in caves: one is a real cave animal. This animal can only live in caves. Without the cave environment, it loses its ability to survive outside the cave. Representative animals are: blind fish, blind loach, spider and scutiger. This kind of animal is characterized by obvious deterioration or disappearance of eyes, special sensory organs, lack of pigment, low metabolism, slow growth, poor reproductive ability and long life.
The second is cave animals. The eyes and body colors of these animals have changed to varying degrees, and they can basically adapt to cave life and reproduce.
The third is a quasi-cave animal. These animals love caves. They live in caves temporarily and seasonally.
Water cave cave creatures At present, cave animals found in caves mainly include bats and stoves. Most of these animals are temporary immigrants from outside the cave, or horses, Ma Lu and moths that have adapted to the cave. Fish (white floating fish), shrimp and mussels can be seen in underground rivers. Cave animals with no obvious changes in their eyes, body color and other organs can see their living environment but have not achieved genetic variation.

Five Tour Guides in Benxi Water Cave, Liaoning Province (5)
Benxi Water Cave Scenic Area is located in the eastern suburb of Benxi City, Liaoning Province, China, 26 kilometers away from the city center. Benxi Water Cave is the longest underground water-filled cave in the world, which was opened to the public on 1983. 1994 was approved by the people of China and the State Council as a national key scenic spot; 1997 was accepted as the first member of Asia by the International Tourist Cave Association; In March 2000, it was rated as AAAA-level scenic spot by the National Tourism Administration and passed the ISO9002 quality system certification. Since Benxi Water Cave was officially opened to the outside world, it has received more than 8 million Chinese and foreign tourists from 120 countries and regions, including heads of state and government from 40 countries. Known as "northern treasure", "world wonder", "first-class in Asia" and "rare in the world".
Benxi Water Cave Scenic Area is a national key scenic spot centered on water caves, including hot springs, Miaohou Mountain, Guanmen Mountain, tanggou Mountain and Tiesha Mountain. It integrates natural landscapes such as mountains, water, caves, springs, lakes, forests and human landscapes such as temples and ancient human sites, and together with Dalian seaside, Qianshan scenery and Changbai Mountain scenery, it constitutes one of the scenic spots in Northeast Asia.
Benxi Water Cave is a large water-filled cave formed millions of years ago. It is located on the Prince River in the eastern mountainous area, 26 kilometers away from Benxi City. East longitude 124 degrees 5 minutes, north latitude 18 minutes. There are two holes in the cave: the diversion hole and the dry hole. The entrance of Benxi Water Cave is located on the north and south sides, with a height of16m and a width of 25m. It is half-moon-shaped, and the upper end is engraved with the four characters "Benxi Water Cave" inscribed by Bo Yibo. The entrance to the cave is the "welcoming living room", which is more than 20 meters high and 20 meters wide and can accommodate thousands of people. On the right side of the hall, there is a dry cave 300 meters long. The caves are patchwork, with holes in them, twists and turns, and each has its own hole. Stalactites on the ceiling and rock wall develop in groups along the cracks, showing various shapes, which are natural and interesting, just like the Dragon Palace Wonderland. Ancient wells, Longtan, Baibu Pool and many other landscapes make tourists daydream and linger. At the end of the hole is a clear pool, bottomless, and the water vapor hits, which makes people feel sad and cold.
