【摘要】 为了解矿区塌陷水体的水质污染特征及规律,结合物理、化学和生物指标,运用营养状态综合指数法及基于ARCGIS的空间差值分析法对淮南矿业集团谢桥矿塌陷塘水质进行了分析与评价。矿区塌陷塘水质pH值呈弱碱性,透明度较低,BOD5、CODMn指标含量较高;用营养状态综合指数法对塌陷塘水质富营养化进行了评价,其污染级别为轻度富营养;运用ARCGIS的空间分析模块,利用总磷、总氮、BOD5、CODMn4个因子的空间插值栅格图建立多因子综合污染模型进行综合评价,得出水体综合水质标准处于地表水Ⅲ类到Ⅳ类之间,水质有待改善。本研究结果为塌陷塘水体水质监管及管理提供科学依据。更多还原

【Abstract】 In order to understand the features and regularity of of water pollution in subsidence,combining with physical,chemical and biological indicators,using nutrition state comprehensive index method and space difference analysis method which based on ARCGIS,analyzed and evaluated the water quality of Xieqiao Coal Mine subsidence pond of Huainan Mining Group.The pH value of water was weak alkali;the SD of water was low;the index of BOD5,CODMn were high.Evaluated the degree of eutrophication with the method of trophic state comprehensive index,the pollution level was light eutrophication.Through the ARCGIS spatial analysis module,Draw out the contaminated distribution simulation diagrams of TP,TN,BOD5,CODMn,and based on the more comprehensive pollution factor ARCGIS model,drawing the comprehensive pollution evaluation simulation diagram of Huainan Xieqiao mine subsidence ponds water quality,obtaining the result that the comprehensive water quality standard of Xieqiao mining located in Ⅲ to Ⅳ,the quality of water should improved.The results of this study provided the scientific basis for water quality supervision and management of collapse pond.更多还原
