Based on the "Three Chart" Method of Groundwater Vulnerability Assessment

Abstract

Abstract:Analysed the research of groundwater vulnerability assessment worldwide actuality, considered the groundwater system vulnerability should be included in groundwater systems anti-fouling and groundwater system vulnerability.Based on the coupled technique of ANN-GIS, a "Three Chart" method was proposed, the maps of distribution of antipollution and the facility-pollution are compounded, and the distribution of the vulnerability of groundwater system is confirmed.
