【摘要】 以榆林神府矿区为例,进行了矿区生态环境现状的评价研究。用系统聚类与Delphi法结合筛选参评因素,层次分析法(AHP)确定其权重,在GIS软件中用矢量数据叠加确定矿区生态环境现状的等级。结果显示,神府矿区因长期煤炭开采生态环境破坏严重,一等、二等地即生态破坏较严重的区域占总面积的47.9%;三等地即生态环境略有破坏的区域主要分布在神木县的中部,占矿区总面积的37.8%;四等地即生态环境安全的区域仅占14.3%。生态环境现状等级与煤矿分布呈明显的正向关系。更多还原

【Abstract】 Taking the Yulin Shenfu Mining Area as an example,the paper conducted a study on ~sessment of ecological environment sta- tus of the mining area.With the system cluster and Delphi method in combined with the screening assessment factors,the AHP method was applied to set its weighting.The data vector superposition was applied to the classification of the ecological environment status in the GIS software.The results showed that due to the long period coal mining,the ecological environment was seriously destroyed.The first class land and second class land that the ecology was seriously destroyed had taken 48% of the total area.The area with some destroyed ecological environment were located in the middle of the Shenmu County and taking 37.8% of the total area.The fourth class land with safe ecological environment was taking 14.3% of the total area.The classification of the ecological environment status and mine distribu- tion had an obvious normal relationship.更多还原
