【摘要】 随着地表水资源开发利用潜力降低和污染加剧,人类对地下水的开发利用程度不断增加,不同程度改变了地下水环境,尤其是城市地区的地下水环境有恶化趋势。采用DRASTIC指标体系和MAPG IS的空间叠加功能,对玉溪盆地地下水防污性进行评价,评价结果表明,该区地下水防污性总体在差—中等范围,可分为三种等级区。其中,盆地区地下水防污性基本在较差—差的范围,盆地周边山地防污性中等。反映人类工程和经济活动易对盆地地下水造成污染。更多还原

【Abstract】 Reducing along with the surface water resources and the intensify of the pollution,the humanity increases unceasingly to the groundwater development degree of utilization,the varying degree changed the groundwater’s environment,the groundwater environment of city area has the worsened tendency in particular.Based on the DRASTIC guideline system and the spatial nestification of MAPGIS,the essay analyses the groundwater antipollution capability,the evaluation result tested to be: the area’s groundwater antipollution capability total varies from low to middle,it is divided into three kinds of grade areas.Among them,the basin area’s groundwater antipollution capability is basic in worse scope;the peripheral basin antipollution capability is in medium scope.It reflects that mankind’s engineering and economic activities pollute the basin groundwater easily.更多还原
