基于DRASTIC模型的城市地下水脆弱性评价综述

Review on Urban Groundwater Vulnerability Assessment by Using DRASTIC Model

地下水脆弱性评价是环境规划和决策的有用手段,国内外已有很多研究,也提出了各种计算防污性能的模型。文章针对城市地下水污染问题介绍了评价地下水防污性能的DRASTIC模型。对DRASTIC模型的指标体系和评价方法进行了介绍,列举了DRASTIC模型的局限性;综述了目前国内外基于DRASTIC模型的城市地下水脆弱性分析的改进的模型及其应用实例,并对其应用前景进行了展望。

Groundwater vulnerability assessment is a useful tool for environmental planning and decision-making.Many studies have been carried out and several models have been developed for assessing groundwater vulnerability worldwide.In the paper,it introduces the DRASTIC model which assesses groundwater vulnerability.It also presents the index system as well as evaluate method and specifies the limitations of the DRASTIC model;after that,it summarizes modified models of the DRASTIC model and the apply cases,finally,it outlooks the apply prospect of the model.
