Abstract

Abstract: EPA’s DRASTIC method was apllied to evaluate the groundwater vulnerability of Lijiang Basin in the historical city of Lijiang in Yunnan Province with the consideration of depth to the water table,net recharge, aquifer material, soil type, topography, impact of vadose zone and hydraulic conductivity of aquifer from the natural environment and humankind activities with the help of GIS technology.The research results show that Lijiang Basin is of high vulnerability,severe pollution and low security of water resources,which has threatened the groundwater ecology safety of Lijiang heritage site. Enforcing comprehensive research and protection of water resource environment is one of the most important work to make the society, economy and environment harmonious development in Lijiang area.

Key words: groundwater vulnerability, DRASTIC, GIS, water pollution, Lijiang Basin
