The Reengineering Technical Analysis For Landscape Reclamation In Subsidence Area Induced By Coal Mining

The large-scale mining and use of coal resources plays a significant role in the economic development of China. However, it also causes a series of negative impacts on our living environment.With the population resources and environment have become increasingly prominent, the land-use issues that it causes receives the attention.The state of land resource of China especially plantation is extremely serious, the contradiction between population and land is more and more prominent, many people and little land is our country’s fundamental realities, the reasonable use of land resource relates to the sustainable development of social economy. Mining subsided areas are effective reserve resources, which effectively relieves the contradiction between land and population in China by sustainable usage of developing and recultivating lands. Therefore, the ecological restoration and management of mining-induced subsidence area has become a problem to be solved in China, considering the sustainable development of economic society and ecological environment. Furthermore, the ecological protection and the development of restoration technology of mining area has become a priority with the national program for long-term and medium-term scientific and technological development plan outline and the12th Five-Year Plan. And meanwhile the development of green mining has been proposed to promote the ecological restoration and management of mining-induced subsidence area. Above all, it has become one of the main research topics to restore the mine ecological environment in our country nowadays.In the paper, we researched the landscape ecological reengineering technology of mining-induced subsidence area, and managed the mining-induced subsidence area, using landscape ecology, restoration ecology, and other relevant theory and taking example by the practical experience of the landscape ecological reconstruction of mining-induced subsidence area at home and abroad.It emphasized that only the planning and design of the reclamation and reconstruction work be made by following the basic principle, the landscape ecosystem of logical structure, powerful and good benefits can be realized.Finally, based on the landscape ecological restoration of Panjiayao coal mine and Hongsheng Antai coal mine, the paper competed to reclaim subsidence land by adopting variety techniques, which closely coupled with theoretical approaches above and actual situation of various mine.
