Zhejiang's natural resources

There are more than 30 lakes in Zhejiang, such as West Lake and Dongqian Lake, with a volume of 654.38+0 million cubic meters and a coastline (including islands) of more than 6400 kilometers. From north to south, there are eight river systems, such as Tiaoxi, Beijing-Hangzhou Canal (Zhejiang section), Qiantang River, Yongjiang River, Lingjiang River, Oujiang River, Feiyun River and Aojiang River, among which Qiantang River is the largest river. Except Tiaoxi and Beijing-Hangzhou Canal, the above eight rivers all enter the sea alone.

Zhejiang is located in the subtropical monsoon climate zone, with abundant precipitation, with an average annual precipitation of about 65438 0.600 mm, which is one of the regions with abundant precipitation in China. The average total water resources in Zhejiang province for many years is 93.7 billion cubic meters, but due to the high population density, the per capita water resources are only 2008 cubic meters, and the per capita water resources of Zhoushan and other islands with the least amount are only 600 cubic meters. Zhejiang Province is rich in marine resources, with a total coastline of 6,486.24 kilometers, accounting for 20.3% of the country, ranking first in the country. Among them, the mainland coastline is 2200 kilometers, ranking fifth in China. There are more than 3,000 coastal islands, with a continental shelf area of 230,000 square kilometers and a sea area of 260,000 square kilometers within 200 meters. There are 306/kloc-0 islands with an area of over 500 square meters, which is the province with the largest number of islands in China. Its land area is19.404 million hectares, and more than 90% of it is uninhabited. Zhoushan Island (the main island of Zhoushan Archipelago) covers an area of 495.4 square kilometers and is the fourth largest island in China.

Zhejiang has a long coastline and deep water. It can build 290.4 kilometers of deep-water coastline of berths above 10,000 tons, accounting for more than China13, and 65,438+berths above 10,000 tons 105.8 kilometers. The East China Sea shelf basin has a good prospect for oil and gas development. Ports, fisheries, tourism, oil and gas and beaches are five resources with unique advantages. By 20 13, there are 58 ports and 650 berths with an annual throughput of 250 million tons. The coastal beach resources are 266,800 hectares, ranking third in the country. Zhoushan is the only island city in Zhejiang Province, and it is also one of the national key development areas.

Zhejiang has a vast sea area, mild climate, fertile water quality and rich bait, which is suitable for the habitat, growth and reproduction of various marine life. There are many kinds of creatures, so it is called "China Fish Warehouse".

Zhejiang's marine aquaculture varieties: grouper, abalone, scallop, sea cucumber, eel, black snapper, red snapper, perch, etc. ? Yellow croaker, yellow-striped bass, puffer fish, egg-shaped pomfret, mullet, sea eel, Odontobutis sinensis, China prawn, Japanese prawn, Penaeus monodon, Macrobrachium nipponense, Portunus japonicus, blue crab and hippocampus. Land survey is an important survey of national conditions and national strength. The second land survey in Zhejiang Province began in 2007 and lasted for three years. By 20 10, 1, the survey results at standard time points (12, 2009, 3 1) were summarized and analyzed, and the land use situation in Zhejiang Province was fully understood, and the base of various land resources was mastered. 2065438+On June 20th, 2004, with the consent of the provincial government, the Provincial Department of Land and Resources and the Provincial Bureau of Statistics jointly announced the main data of the second land survey in Zhejiang Province today.

According to the results of the second survey, by June 65438+February 3, 20091(standard time), there were 29,800,300 mu of cultivated land in Zhejiang province, accounting for 18.83%. Garden 9.4352 million mu, accounting for 5.96%; 85.3094 million mu of forest land, accounting for 53.91%; Grassland 1557600 mu, accounting for 0.97%; Urban villages and industrial and mining land 1334900 mu, accounting for 8.43%; Traffic land is 3190,700 mu, accounting for 2.02%; Land for water conservancy and water conservancy facilities12,895,300 mu, accounting for 8.15%; Other land is 2,735,300 mu, accounting for 1.73%.

According to the data, at the end of 2009, the cultivated land area ratio in Zhejiang Province decreased by 2,079,800 mu when 1996 was first investigated, and the per capita cultivated land decreased from 0.72 mu when 1996 was first investigated to 0.56 mu, which is about one third of the national per capita cultivated land. The basic situation of small amount of cultivated land, low quality of cultivated land and insufficient reserve resources in Zhejiang Province has not changed, and the situation of cultivated land protection is still very grim. We must unswervingly adhere to the strictest farmland protection system.

According to the data of the second survey, the area of construction land in Zhejiang Province increased by 405,800 hectares (6,086,500 mu) at the end of 2009 compared with the first survey 1996. Although the increase of construction land meets the needs of economic and social development in Zhejiang Province, compared with developed areas, there is still much room for improvement in the level of economical and intensive utilization of construction land. At the same time, the contradiction between supply and demand of construction land is still very prominent, and we must unswervingly continue to adhere to the strictest land-saving system.

The soil in Zhejiang Province is mainly yellow soil and red soil, accounting for more than 70% of the area of Zhejiang Province, mostly distributed in hills and mountains, mostly paddy soil in plains and river valleys, and mostly saline soil and desalted soil along the coast. There are many kinds of minerals in Zhejiang Province, including iron, copper, lead, zinc, gold, molybdenum, aluminum, antimony, tungsten and manganese, as well as alunite, fluorite, pyrophyllite, limestone, coal, marble, bentonite and aragonite. Alum reserves rank first in the world (60%), and fluorite reserves rank second in China.

1 13 minerals have been discovered in Zhejiang province. By the end of 2009, there were 93 kinds of minerals (excluding oil and gas and radioactive minerals) in Zhejiang Province. There are 2,392 mining areas in Zhejiang Province, 302 fewer than the previous year, including 2,343 solid mineral areas and 49 geothermal mineral water areas.

Non-metallic minerals are abundant, and the proven reserves of some minerals rank among the top in the country. In terms of proven resource reserves, alunite and pyrophyllite rank first in China, fluorite, illite and cast diabase rank second in China, facing diorite ranks third, and zeolite, wollastonite, travertine, boron ore, bentonite and perlite rank top ten. Most deposits are large in scale, shallow in burial and good in mining conditions.

There are many metal deposits, but the scale is not large. There are many minerals such as iron, copper, molybdenum, lead, zinc, gold, silver, tungsten and tin in Zhejiang Province, but most of them are small-scale deposits or occurrences, and only a few of them reach large and medium-sized scale. The ore composition is complex and there are many elements.

The geological conditions of coal formation in the province are poor and coal resources are poor; Oil and gas resources have not been found on land, but the oil and gas prospects in the sea area are promising. There are more than 3,000 kinds of vegetation resources in Zhejiang Province, and 45 kinds of wild plants are under special state protection. Rich in tree species resources, it is known as the treasure house of southeast plants.

Zhejiang has 6,679,700 hectares of forestland, including 5,844,200 hectares of forests. The forest coverage rate is 60.5%, and the total volume is 65.438+0.94 billion cubic meters. Among the forest areas, the area of arbor forest, bamboo forest and shrub forest specified by the state is 420 1.800 hectares, 782,900 hectares and 859,500 hectares respectively.

The forest coverage, bamboo area and the number of trees in Zhejiang are among the best in China. Among them, the area of bamboo forest accounts for China 1/7, and the output value of bamboo industry accounts for China 1/3. The forest community structure is relatively complete. The area with complete three-layer structure of arbor, shrub and grass accounts for 54.2% of trees, and the area with simple structure of tree layer only accounts for 1.5% of trees. The forest health is good, and the proportion of healthy and sub-healthy forest areas is 88.45% and 8.23% respectively. Generally speaking, the diversity of forest ecosystem belongs to the upper-middle level, with rich forest vegetation types, forest types and arbor age groups.

There are many kinds of wild animals, of which 123 are listed in the national list of key protected wild animals. There are more than 80 species of wild animals and 300-400 species of birds, including 22 species of national first-class protected animals, 2 species of second-class protected animals 103 and 44 species of provincial protected animals.
