摘要
Abstract
The Huangshui River is located in arid region of northwest plateau.Based on groundwater characteristics of the watershed,this paper selected six factors:the impact of vadose zone,groundwater depth,aquifer type,aquifer thickness,net recharge and topography to build up an improved DRASTIC model by using AHP to give the weight of each index.Using improved DRASTIC model to evaluate the grotmdwater vulnerability in small watershed scale of the Huangshui River,the results showed that the high groundwater vulnerability area distributed partly along the Huangshui River and the Xipu village,and the groundwater was vulnerable to pollution.Compared with the traditional DRASTIC model,the improved DRASTIC model is more consistent with the actual condition.关键词
