| 摘 要： | 本文对西安市地下水中六种主要污染物的均值和超标面积进行了数值模拟,验证了环境库兹涅茨曲线(EKC).结果显示,西安市地下水的总硬度、氟化物、六价铬的均值和超标面积都处于环境库兹涅茨曲线(EKC)的第三、四阶段(衰退期),硝酸盐、氯化物的均值和超标面积处于四、五阶段(消亡期),而总固体的超标面积处于三、四阶段,均值处于四、五阶段.

| Abstract: | The article carries out the numerical simulation for the mean value and the exceeded standard area of six major contaminations of groundwater in Xi'an city and confirms the EKC.The result shows that the mean value and the exceeded standard area of the general rigidity,Chloride and Cr~(6 ) of groundwater in Xi'an city are all located in the 3rd and 4th phases in the EKC(declining phase).Nitrate and Chloride's are located in the 4th and 5th phases,(extinction stage),the exceeded standard area of the general solid is located in the 3rd and 4th phases and their mean values are located in the 4th and 5th phases. |
