湖北五峰南河流域大气降水方程求取

Seeking the Atmospheric Precipitation Equation in the Nanhe River Drainage Area,Wufeng County,Hubei Province

在研究分析流域内特殊地质条件和水文地质条件的基础上,试图利用河水、地下岩溶水的δD-δ18O稳定同位素测试分析资料求取当地大气降水线方程。从所得结果来看,在资金较少,其水文地质条件比较适宜的岩溶山区,利用这种方法可以粗略地求得当地的大气降水线。

This paper discusses the special geologic and hydrogeologic conditions in the Nanhe River drainage area, where we tries to work out the local atmospheric precipitation equation by using the analytical data of stable isotopesδD and δ18O of surface water and underground karst water.The result shows we can get the local atmospheric precipitation equation in an approximate way by the method introduced in this paper in the karst mountainous areas, where the economic conditions are poor, but the hydrogeological ones are porper.
