Abstract:

In order to utilize the groundwater resources in a scientific and rational way, and provide water resources guarantee for water-deficient area, it was very necessary to carry out the research of groundwater environmental capacity. On the basis of analyzing connotation of groundwater environmental capacity, the concept of groundwater environmental capacity was defined, and the comprehensive environmental capacity was put forward. The QVLTE index system and R index were established by comparing current indexs of the groundwater environmental capacity and the concept of comprehensive environmental capacity. Groundwater quality and water volume were the main impact factors by applying the system of QVLTE to Jingsheng basin. The results closely meet the actual situation. Research results would provide basis for the conservation of groundwater and the healthy development of agriculture.
