摘要/Abstract

摘要： 以地理信息系统(Blackland GRASS软件)为基础平台,建立了西湖流域基础和专题数据库;结合地下水污染风险评价专业模型(DRASTIC模型),计算出流域内地下水污染风险图.对照流域的土地利用现状,提出流域内的污染优先控制区.研究表明,地下水污染高风险区中,居民区占了14.7%.在流域地下水污染防治中,建议首先对优先污染控制区内的居民区进行生活污水截污.

关键词: 地下水, 污染风险, DRASTIC模型, 地理信息系统

Abstract: Supported by Blackland GRASS Geographic Information System(GIS),the basic and special environmental databases of West Lake Watershed were established.The vulnerability map of ground water pollution was calculated and drawn by integrating GISand DRASTICmodel.Comparing to the present situation of land use,critical area of ground water pollution had been determined.The residential area accounted for 14.7% of the high susceptible area,and wastewater in the residential area should be piped and treated first.

Key words: Ground water, Vulnerability, DRASTIC model, Geographic Infromation System
