Abstract:: The DRASTIC,one of the wildly applied systems for groundwater vulnerability evaluation,is reviewed and the main problems are analyzed.According to the practical situations of Sanjiang Plain,an evaluation method namely DRASCLP is suggested based on the Entropy Weight.In this method,seven indexes are selected as the parameters,and the weight of each factor is calculated by the entropy-weight coefficient method,and the space superposition function of GIS technology can be used to evaluate groundwater vulnerability.The results show that groundwater vulnerability presents the trend of decrease from northwest to southeast,which provide a decision basis for utilization and protection of groundwater resource.
