摘要
为了评价湛江市地下水资源承载力,防止地下水过度开采所造成的生态环境问题,基于主成分分析方法建立湛江市地下水资源承载力评价指标体系,对湛江市地下水资源承载力进行评价。综合评价结果表明湛江市各行政区综合评价值各不相同:市区>徐闻县>遂溪县>吴川市>雷州市>廉江市。市区的综合评价值最高,分值达53.817,说明相对于其他行政区,市区的地下水资源开发潜力较小,承载力已趋于饱和,继续开发利用的潜力甚小。
In order to evaluate groundwater resources carrying capacity of Zhanjiang and prevent ecological and environmental issues caused by over- exploitation of groundwater, evaluation index system of Zhanjiang groundwater resources carrying capacity is established based on principal component analysis （PCA） method, and the groundwater resources carrying capacity of Zhanjiang is evaluated. The general evaluation shows that the comprehensive values of boroughs are different ： Downtown 〉 Xuwen 〉 Shuixi 〉 Wuchuan 〉 Leizhou 〉 Lianjiang. The comprehensive value of Downtown is highest and the score is 53. 817. Compared with other boroughs, the exploring and utilizing potential of groundwater resources is smaller and the carrying capacity has become saturated.
