The Study on Eco-Environmental Influence of Mineral Resource Exploitation - Cased by Yalong River Basin in Jiulong County
Yalong river basin is located in the southeast of the qinghai-tibetan plateau. This area is the important mineral resources region, where ecological environment problems caused by mineral resources development are uncertain and complicated. It is necessary to understand the influence of mineral resources development urgently and control human activities scientifically. In this paper, the eco-environment influence of mineral resource exploitation is studied on basis of geochemical data and remote science, and dividing into mining point distance, soil type, land cover, vegetation coverage and the soil erosion. The method of principal component analysis is adopted to sort the corresponding degree of various factors. Then the impact of mineral resources development on ecological environmental factors can be mastered overall, which providing decision basis for mining development measures.
