淮南市区浅层地下水水环境质量评价系统(附开题报告)

摘 要 地下水质量评价方法很多，在评价模式、评价标准和质量分级等方面都存在不同的认识。在具体的工作中，选用合适的评价方法是非常重要的，同时，由于各种评价方法所得结果有时并不能令人满意，因此从不同角度评价地下水水环境质量也是很有必要的。 本文分别应用了模糊集理论、综合水质指数及GIS技术支持下三种方法从不同角度对淮南市区浅层地下水质量进行评价，从而使评价结果趋于合理化。 关键词：水质评价、模糊集理论、综合水质指数、GIS Abstract Many methods are applied to evaluate the quality of groundwater, and there are different views in evaluation model, evaluation standard, quality graduation and other aspects. In practical work, it’s very important to choose appropriate evaluation method. Meanwhile, the results of all kinds of methods are often dissatisfactory, so it’s very essential to evaluate the environmental quality of groundwater from different aspects. From different angles, this paper makes a comprehensive evaluation of the quality of shallow groundwater in HuaiNan with three methods—fuzzy group theory, comprehensive index of water quality and the technique of GIS, and the result comes to be reasonable and comprehensive. KEY WORDS: water quality evaluation、 fuzzy group theory、 comprehensive index of water quality、 GIS
