污染的孝妇河对其流域裂隙水化学环境的影响

根据孝妇河的纳污情况选择了３个断面，定期采样分析监测河水水质．对１９８９—１９９６年的监测结果的分析整理得到河水化学组分含量的变化特征．从水量和水质两个方面证明了引起河流污染的主要原因是矿坑水的排入．研究了河水与裂隙水之间的接触关系，发现两者之间不仅存在联系通道，而且裂隙水的水头明显低于河水水头．说明河水可以渗漏的形式补给裂隙水，引起裂隙水的污染．同时也从水化学的方面找到了污染的河水影响裂隙水化学环境的证据．

Effect of contaminated river on the fissure water in its watershed

Based on Xiaofuhe River's condition, three sections were selected along the river channel to monitor the content dynamic variation of aquatic chemical components.It was identified that the mine drainage was the river's main pollution source in the eyes of the water quantity and quality. The contact relationship between the river and the fissure water was studied. It was found that a pathway existed between them and the frontier's head was higher. In the consequence, the contaminated river recharged and contaminated the fissure water by seepage.
