Abstract: Based on the collection and utilization of previous research in Yangzhuang basin,this paper carried out the sampling and monitoring of Hydrochemistry and isotopes,and studied evolution of the hydrochemistry process in Yangzhuang basin,which is aiming at laying a foundation for the study of Karst Critical Zone.The results show that the main type of Karst water in the study area is HCO₃-Ca,and the main supply source is atmospheric precipitation.In the process of runoff generation,Karst water has strong interaction with limestone,and to some extent,it is affected by evaporation,cation exchange and mixing.Affected by human activities,the content of NO₃^-and SO₄^2- in some areas is relatively high.
