基于模糊层次综合法在地下水资源量和水质评价中的应用——以开阳县冯三镇为例
|
摘要
通过大气降水入渗系数法和开采系数法计算得出,地下水天然补给量平均值为3115.84万m~3/a,允许开采量为1065.53万m~3/a。采用层次分析法与熵权法相结合的组合赋权法进行权重赋值得出冯三镇综合水质良好,水质类别在Ⅱ~Ⅲ级,其中主要的污染物为硝酸盐氮、总硬度和挥发酚,各评价指标的权重系数更符合实际水质情况,较传统模糊综合评价法可靠、合理,评价结果具有很好的一致性。
The average value of natural recharge of groundwater is 3115.84 million m~3/a,and the allowable exploitation is 10,655,300 m~3/a,which is calculated by the atmospheric precipitation infiltration coefficient method and the mining coefficient method.The combination of analytic hierarchy process and entropy weight method is used to determine the weight of Fengsan town.The water quality is in grade Ⅱ ~ Ⅲ,and the main pollutants are nitrate nitrogen,total hardness and volatile phenol,The weight coefficient of each evaluation index is more consistent with the actual water quality situation,which is more reliable than the traditional fuzzy comprehensive evaluation method,and the evaluation result is very consistent.
