Abstract
According to the results of the hydrochemical analysis of fractured Karst water in the dry season of 2015 in the Dasunzhuang area, the correlation between the indexes of hydrochemical composition was determined, and the influence factors and degree of Karst water formation in the area were discussed by the factor analysis method. The results show that: Hydrochemical composition has a large range of changes and has obvious spatial variability; The formation of hydrochemical composition is mainly controlled by three main factors. The three main factors can explain 81.221% of the formation of groundwater water quality. The main factor 1 represents human activities, the main factor 2 represents the influence of water-rock action, and the main factor 3 reflects natural factors such as soil and plants; By combining the results of factor analysis with hydrogeological action, the formation mechanism of hydrochemical composition is analyzed. The results confirm that the use of factor analysis method to study the formation mechanism of groundwater hydrochemical composition is a reliable and effective method, which has the advantages of simple operation, strong operability, and intuitive and accurate results.关键词
