摘要
Groundwater is a large and complex underground system,and its chemical characteristics influencing factors have greater diversity which may be a factor group or factor group,such as climate,topography,thermal power,water power and human activities.This paper according Lizhou and Zhongxing-yutang two regions′ geological structure characteristics to divide the different hydrogeological sub-region,the main lithology of the aquifer,And analysis and comparison of the groundwater chemical characteristics of the two regions,determining the influencing factors of groundwater chemical characteristics.To provide a scientific basis for the study of groundwater systems characteristics and the rational development of water resources.
