延河泉域岩溶地下水环境保护措施

Protect Distributions of Karst Groundwater Environment in Spring Area of Yanhe

通过对延河泉域地质、水文地质和水文地球化学分带特征的分析,运用热力学方法计算,确定了碳酸盐岩、硫酸盐岩矿物溶沉方向的反应比率(饱和指数),以此划分了岩溶地下水的环境保护区,并提出了保护措施。

The article is based on analysis of distribution characteristics in geologic, hydrogeologic and hydrology geochemistry in the Spring area of Yanhe. By calculation in the thermodynamic method, it determines the reactive ratio （saturation index） of mineral dissolution sediment of carbonate rock and sulfate rock, therefore, partitions the environmental protection area of Karst groundwater and puts forward protection measures.
