The Sdudy About Ecological Restoration And Landscape Construction On Cheng Jiao Coal Mine Subsidence Area In City Of Yong Cheng

Coal has been always the main energy to support industrial development since human society entered the industrial age. Although coal is gradually replaced by the green new energy such as solar energy, wind energy. But the left problems from old industrial age is lingering and increasingly highlighted.Due to the start of industrialization is later in China. So, many heavy industries such as power, steel in a short period of time is still difficult to get rid of the dependence on coal. Many coal enterprises and local government just focus on the economic benefits and ignore the ecological environment deterioration. The contradiction caused by coal mining between resources exploitation and land conservation is more and more obviously. At the same time, our country is a country rich in coal resources, according to statistics, there are about more than 80000 places, village and township coal mines in 109 counties in China. The resource is drying up after dacade exploration in many coal resource cities due to a lack of rational mining plan and protection measures after the mining.The development of these cities lack of subsequent force, and large surface subsidence caused by mining. It destructed the land resources. Local descendants living space will be under serious threat.As the largest anthracite coal producing area in eastern of henna province. Coal mining started the late 1980 s.It has formed a number of large and small coal mining subsidence area in the surrounding suburbs and downtown township of yongcheng. In order to find an effective way to improve in coal mining subsidence ecological environment. this paper takes yongcheng between xicheng district and dongcheng district in suburban ore mining subsidence as an example, study the following:(1) Base on the theory of restoration ecology, for nearly a decade, the subsidence of surface changes, changes in vegetation and ecological structure comparison research;(2) Base on the theory of urban ecology, urban planning principle, expounds the emergence of the subsidence of city environment, the influence of urban development and the advantages and disadvantages;(3) Base on the basis of landscape ecology, combining with the local government dominated in the subsidence renovation project, study and discuss with landscape means to repair the feasibility of the subsidence of the ecological environment and the actual effect. Summarize the problems existing in the present, and puts forward reasonable and effective Suggestions and ideas.Through the research to explore an effective way to restore the subsidence of the ecological environment, and propose the subsidence of the landscape construction planning ideas and set up the model.
