焦作裂隙岩溶水系统是我国北方岩溶区发育比较典型的系统之一 ,岩溶水资源丰富 ,水质优良 .最近几年来的水质监测结果显示岩溶水已受到污染 ,突出表现在岩溶水Cl- 含量逐年升高 .通过建立分散参数二维溶质运移模拟模型 ,以Cl- 为模拟因子对污染原因、污染源进行了模拟计算 ,证实岩溶水Cl- 升高是人为污染所致 . The Jiaozuo fissure karst water system is one of the typical systems developed in the karst area of ​​northern China, with rich karst water resources and excellent water quality. The monitoring results of water quality in recent years show that the karst water has been polluted, especially in the karst water The simulation model of two-dimensional solute transport with dispersed parameters was established, and the causes and sources of pollution were simulated with Cl- as a simulation factor to confirm that Cl-elevation in karst water was caused by human pollution.
