For thousands of years, although the history of change, people change, but the city and the river can generally live in harmony, respect each other as guests. Into the era of industrialization, the city and the river as if overnight into an enemy, wagging each other. Discharge of sewage, crazy sand mining, cutting down trees and destroying forests, the mother river has been nurturing their own, the city "to return the favor". The river is also not willing to be humiliated, sediment, muddy water, flooding the city, so that the city can not rest.
Conflicts intensified, both sides lose, the city and the river between how?
The reporter interviewed in the relevant departments, found that the main reason is due to the uncontrolled development of the city, man-made destruction to the city rivers to bring harm and trigger.
With the accelerated industrialization process around the world, many cities built industrial zones, a large amount of industrial wastewater is discharged directly into the river without treatment. There is domestic sewage and domestic garbage, Longnan County, for example, did not carry out river management, the county's population of 100,000 people produce 40,000 tons of sewage every day, most of them through the scattered sewage pipes discharged into the river, 80 tons of urban garbage every day, a considerable portion of the people were thrown into the river. Urban rivers have become cesspools and garbage dumps. According to a survey, 90% of the current national urban waters are polluted to varying degrees.
As urban construction requires a large amount of river sand, sand mining activities have become uncontrolled. It is understood that in some places, the larger the river, there are often more than 10 sand quarries in full production, resulting in serious damage to the river, the collapse phenomenon is frequent. And urban construction waste dumped randomly in the river, but also make the riverbed water level, posing a threat to urban safety.
Dry rivers and riverbanks are part of the river channel and have a natural regulating effect on flooding. Due to urban expansion, the dry rivers and river banks of urban rivers in many places have been occupied for farming, tourism development, building houses and factories. When flooding strikes, cities lose this natural barrier and are much more likely to be flooded.
Urban development and river management, how to unify the two
Urban development and river management can not be the best of both worlds? How should rivers be managed to truly benefit the long-term development of cities?
"Clear water, green banks, smooth" is the primary goal of urban river management. Based on a variety of considerations, Longnan County on the river management put forward and implementation of the "prevention and management, natural and artificial harmony" idea.
Intercepting pollution and clearing, so that the urban river from turbid to clear. In the industrial pollution "heyday" period, Longnan County had 19 strip steel production enterprises, hundreds of rare earth, tungsten sand mining sites without a license. At that time, the polluted river is like a "yellow dragon", "white dragon", "black dragon". In recent years, after the county iron hand remediation, these serious pollution of the river enterprises have been basically shut down. In addition, Longnan County, the implementation of the environmental protection veto system, the polluting enterprises outside the country, become a "talisman" of the city river. In Longnan's urban planning blueprints, conspicuously marked a daily treatment of 50,000 tons of sewage city sewage treatment plant. County Environmental Protection Bureau staff said that the upcoming construction of the sewage treatment plant to the city's domestic sewage in one place, centralized treatment and discharge. Flowing through the county of Longnan in the three rivers, Taoyuan River sand farms, focusing on sand; Wo river pollution, focusing on pollution control; Lianjiang River water flow is small, focusing on the conservation of water sources. Because of the river, highlighting the key points, so that the river management work twice as much with half the effort.
Drawing the dragon and dotting the eyes, so that the city river heritage personality. Longnan has a rich Hakka cultural heritage. City builders are creative Hakka style and river management combined, highlighting the city's distinctive personality. Such as in the construction of Longxiang Square, the county will be a section of 1.6 kilometers of abandoned dry river transformed into a landscape river, the introduction of the Wojiang River water, according to the original miniature Hakka houses, Yang Village Taiping Bridge and Hakka crowd sculpture in the river in the embrace, so that the Hakka flavor of the manmade landscape and the river organically fused with the distinctive flavor. Bridge, is the spine of the river, is the blood of the city. In Longnan County, winding around the city and the Tao River, Wojiang, Lianjiang three rivers, 16 various bridges over the banks, there are mother and child bridge, double-arched bridges, rainbow bridges, etc., and the harmony of both sides of the scenery **** existence, the formation of "a bridge, a landscape", so that the river doubled the anger.
River governance, accelerate urban development
The governance of the city river more clear and pleasant. Longnan will be the overall framework of the urban landscape is positioned as a "three rivers and four banks of the six major landscape area". Once the framework, the taste immediately apparent. Business, culture, landscape, leisure, idyllic.
The reporter noted that in Longnan, the newly assessed city "new eight scenes", there are four closely related to the river, "Taokawa Sunset", "Dongjiang Spring Water", "Dragon gathering phoenix dance", "fishing island hook moon". Indeed, after the governance of the river has become the city's most beautiful, most dynamic a landscape.
After the river governance, Longnan County, three rivers and four banks of the real estate projects through the "pro-water" concept quickly warmed up, a series of "city and water" as the theme of residential areas, recreation areas, commercial areas emerged, neighboring the water of the Riverside Road, Wojiang Road, Longxiang Plaza, Shuitong Market, Longzeju, Waterfront Bay, etc. have become the prime locations of Longnan County. For example, the county next to the Jinshui Avenue, there is a section of the old dry river dam, governance before the stink of duck farms, after the transformation of real estate developers to use the water to revitalize this treasure, built "Longcheng Waterfront Bay" residential area, the price of land turned over five or six times. Water as a gravitational force, Longnan city construction development, prosperity of a piece of the city area rapidly expanding, a former Gan-Guangdong border of the small city has grown into an area of more than 10 square kilometers, the population of more than 100,000 people in Gannan sub-centre of the city, the county's urbanization rate of 34.4%.
In the past, the river was a water conservancy hub and the main channel for flooding in the city. Today, after re-governance and planning of urban rivers, increasingly showing a unique economic function, cultural function and recreational function.
Out of the "pollution - governance - pollution" circle
The governance of urban rivers is not overnight, "pollution - governance -Pollution - governance", many urban river governance is so caught in a loop, back and forth, treating the symptoms but not the root cause. The reason for this, an important point is the lack of an effective long-term mechanism. In this regard, Longnan County has been working on the establishment of urban river governance and management of long-term mechanism. In this set of mechanisms, will set up a permanent organization, coordinated scheduling of municipal, water conservancy, environmental protection, sanitation, agriculture, forestry, finance and other departments to work together, persistent ecological integrated management of urban rivers.
Perseverance does not mean stagnation. Many cities in the river management concept there is a misunderstanding, for example, the river as a simple flood control project and the construction of river embankments, the flow of interconnecting waters into a tributary of the water attractions. Therefore, a good scientific and reasonable long-term planning of river management is extremely critical, on this basis, good adaptability, highlighting the characteristics of the time is also very necessary.
In fact, people are the biggest source of pollution in the river. Drinking water when thinking of the source, most of the city residents to drink tap water from the river, but many people do not cherish this "drinking pool", as a garbage pool, bath, wantonly pollute the river behavior is not uncommon. Therefore, only to improve the quality of citizens, people and rivers are truly interdependent, mutual respect, in order to ultimately make the city and the river harmonious *** place, *** life *** long.
