Study On Ecological Safety Evaluation And Control Strategy In Nanlou Mining Area

With the development of our country’s economy,the mining area has become the key development area because of its unique resource advantage,but there are many problems in the development of mining area,such as excessive development,serious destruction of ecological environment and gradual depletion of natural resources.Since the 18 th National Congress of the Party,China has vigorously advocated the construction of ecological civilization,ecological management and restoration of mining areas are imminent,how to coordinate the balance between resource development and ecological protection in mining areas,Effective selection of new technologies suitable for land reclamation and ecological restoration has become a difficult problem in mining area development.UAV remote sensing technology with the advantages of all-weather,full coverage and real-time dynamic monitoring has become the best choice for ecological management and restoration of mining areas.On the basis of discussing the theoretical knowledge of UAV remote sensing,ecological security and ecological restoration in mining area,taking Nanlou mining area of Dashiqiao City as the research object,using UAV remote sensing technology to obtain relevant data of Nanlou mining area of Dashiqiao,according to the development characteristics of the mining area,selecting six indexes of environmental carrying capacity,soil erosion,landslide susceptibility,biodiversity,vegetation coverage and air pollution to construct the evaluation system of ecological safety factor index of Nanlou mining area,combining RS and GIS technology to quantitatively analyze the present situation of ecological environment quality,Finally,according to the results of the zoning,combined with the present situation,characteristics and sustainable development theory of each district,the paper puts forward the ecological network spatial planning and construction strategy,ecological environment management and control strategy,mining area resource optimization and industrial structure adjustment strategy,in order to provide some reference for Nanlou mining area to formulate sustainable development strategy,regional ecological security management and decision-making.
