生态敏感性分析在矿区规划环评中的应用——以云南恩洪矿区为例

Application of Ecological Sensitivity Analysis in PEIA of the Mining Area—Taking Enhong mining area in Yunnan Province as an example

以云南恩洪矿区为例,选取了土地覆盖类型、高程因子、坡度因子、生物多样性等4个因子,运用遥感/GIS技术,采用AHP法,对恩洪矿区进行了生态敏感性分析,利用专家打分法构造判断矩阵,获得4个因子的权重,计算出了综合生态敏感度,划分为极敏感、敏感、低敏感和不敏感4个等级,并分区提出了保护对策,为煤矿开采合理布局及生态环境保护提供依据。

＂Faking Enhong mining area in Yunnan Province for example,four sensitive factors are selected.including land cover elevation,elevation, slope and biodiversity. Then adopting RS/GIS technology and AHP, the article conducts an ecological sensitivity analysis of Enhong mining area. Using the expert scoring melhod to construct and judge the matrix,the weights of 4 factors are got. The article calculates the comprehensive ecological sensitivity,dividing into four grades, including extreme sensitivity,sensitivity, low sensitivity and no sensitivity. In addition,the article puts forward protection countermeasure, which provide references for the reasonable layout and the protection of the ecological environment of coal mining.
