南方地区地下水功能评价指标筛选研究——以广东省为例

在分析南方地区地下水资源特点的基础上,综合运用理论分析法、专家咨询法和灰色关联度模型,构建地下水功能评价指标体系;以广东省为例探索地下水功能评价指标筛选方法和筛选程序,选择理论分析法和专家咨询法进行第1次指标筛选,选择灰色关联度进行第2次指标筛选。与北方地区地下水功能评价指标进行对比,分析指标的合理性,用得到的广东省地水水功能评价指标体系为依据进行评价,其结果与实际情况基本吻合。

Evaluation index system of groundwater function in southern region of China: A case study in Guangdong Province

On the basis of analysis of the characteristics of groundwater resources in the southern region of China,an index system for groundwater function evaluation was constructed with the theoretical analysis method,the expert consultation method,and the gray correlation degree method.Using the evaluation index system of groundwater function in Guangdong Province as an example,the methods and the procedure for identifying evaluation indexes were studied.The theoretical analysis method and expert consultation method were used in the first identification,and the gray correlation degree method was used in the second identification.To evaluate the rationality of the index system resulting from this screening,it was compared with the index system used in the northern region.There was an agreement between the estimated results and field data.
