Chongqing Qijiang District Songzao Coalmining Ecological Restoration Of Land Ubsidence

Ecological restoration of abandoned coal mine area is one of the important tasks of the current ecological environmental protection, improve and protect ecologicai environment, realize zhe sustainable development is zhe basic national policy of our country, but zhe present situation of ecological environment is still very grim face. The key area is located in the suburb of metropolis in the mining area is the urban-rural integration process, distribution in the region of abandoned coal mine more because of zhe location and zhe characteristics of zheir own in zhe whole process of environmental construction occupies an important position. Chongqing city Qijiang District Songzao Coal Mine Area as China’s early development of coal minearea, due to the long-term large-scale mining, the urrent coal resource gradually dried up,the ecological environment has been very bad situation, the implementation of ecological restoration is imperative.In this paper, using field investigation method, interview method, quantitative and qualitative, on-the-spot investigation mainly negative impacts on the environment status and exploitation of coal Songzao Coal to the environment, under the guidance of the theory, combined with the mine ecological restoration principles, put forward the ecological restoration model of ecological, restoration measures in different types of ecological environment in mine area and the mining area. Through the research of this paper mainly draws the following conclusions:(1) Revealed by analysis of Songzao Mining Coal Mining Subsidence in the temporal and spatial distributionand the damage degree. The time of mining areas for 2005,2009 and 2013 three period is expected; spacemainly on algae, Tonghua coal mine, coal mine coal mine, coal mine, through the spring a mine and YuYang coal mine six coal mine subsidence is predicted.(2) On the algae coal mine as a landscape ecological function regionalization, divided into algae crossing the valley circulation high efficiency ecological agriculture area, middle low mountain forest and grass grain and live stock farming area,,northern low mountain three-dimensional fruit grain and livestock stereo farming area, southern Zhong shan karst forest ecological conservation areas, the northern Zhong shan fruit compound ecological optimization of area five big area. Five landscape ecological fumction district level two, accounted for 2.41% of the total area of appropriate reclamation,90.60%,1.18%,4.68%.1.13%.(3) through the research and analysis, Songzao Mining Area Ecological Tourism to repair th e advantages and technical. Songzao Mining Area eco tourism development mainly has several advantages, location advantages, the unique landscape advantage, tourism and the advantage. Th e mine has mode of industrial tourism, "natural" tourism resources mode, scientific research ex periment base tourism model. In Songzao Mining Area of coal mining subsidence repair technol ogy of ecotourism including, the top of the hill gardentype repair mode, and Gully Water Conse rvation Type repair mode, slope woodland type repair mode, pitfilling type repair mode, "trash a esthetics" landscape reconstruction technology.
