【摘要】 在分析成都平原水文地质条件的基础上,采用DRASTIC评价方法对成都平原浅层地下水天然防污性能进行评价。评价结果表明:地下水天然防污性能较差和差区主要位于山前冲洪积扇和河流一级阶地、漫滩,占研究区面积的35.1%;地下水天然防污性能中等区面积占36.6%;地下水天然防污性能好和较好区面积占28.3%。评价结果可为地方政府制度土地利用规划、地下水资源保护和制定地下水污染防治规划提供科学依据。更多还原

【Abstract】 This paper has discussion on hydrogeological conditions of Chengdu Plain and applies DRASTIC method to evaluation of native vulnerability of shallow groundwater on the Chengdu Plain. The results indicates that groundwater of poor native vulnerability is distributed over piedmont alluvial-pluvial fan, first river level terrace and flood plain, making up 35.1% of total area of the Chengdu Plain, groundwater of medium native vulnerability is distributed over an area making up 36.6% of the total area, and groundwater of good native vulnerability is distributed over an area making up 28.3% of the total area.更多还原
