And then through analyzed the component of the pollutant in the region's groundwater, and considered the good and bad points of each assessment method, we adopted the fuzzy comprehensive evaluation method, and estimated the vitiation of the ground water, which result is conform with the actual degree, and has realized the of the fuzzy appraisal.

本文针对煤矿开采对地下水污染的问题，首先根据研究区域自然地理与水文地质条件分析了煤矿开采对地下水污染机理，然后通过对研究区域地下水污染物组分的分析，考虑各种评价方法的优缺点，采用模糊综合评判法，对煤炭开采对地下水的污染做出了比较合乎实际的评价，并实现了模糊评价的电算化，同时利用Matlab分析了煤矿开采对地下水污染的趋势。

objectiveto provide the scientific foundation for the construction of gap cultivation bases of abrus mollis hance by evaluating the pollution status of soil and irrigation water in abrus mollis hance cultivation base.methodsthe environment quality was appraised by the nemerow pollution index method.resultsthe quality of soil and irrigation water was good, falling in the categories of "clean".conclusionthe quality of soil and irrigation water in abrus mollis hance cultivation base accords with the requirement of gap of chinese medicinal materials.

目的对鸡骨草种植基地土壤、灌溉水污染现状进行评价，旨在为鸡骨草规范化种植基地建设提供科学依据。方法土壤及灌溉水污染现状运用单项污染指数法和内梅罗综合污染指数法进行评价。结果种植基地土壤和灌溉水污染等级均属于&清洁&一级。结论鸡骨草种植基地的土壤和灌溉水质量完全符合《中药材生产质量管理规范》的相关要求。

So this paper analyze characteristic of sudden water pollution accident, and discuss the problem of ecological compensation legislation of sudden water pollution accident in our country. According to this analysis, we educe the proposition of ecological compensation legislation of sudden water pollution accident in our country.
