哈尔滨市地下水的易污性评价及计算机编图

Groundwater Vulnerability Assessment and Mapping in Haerbin

介绍了目前在国际上采用的地下水的易污性评价方法──ＤＲＡＳＴＩＣ评价方法,用与地下水有关的多因子法──地下水的埋深、含水层的净补给、岩性、土壤类型、地形、渗流区介质、水力传导系数等７个相关因子对地下水进行评价,并结合ＧＩＳ地理信息系统对哈尔滨市地下水的易污性进行评价,编制了哈尔滨市地下水的易污图,为今后地下水资源管理、土地利用、城市环境管理者等进一步制定管理方针政策提供了重要的依据。

This paper described the DRASTIC method, which combined with correlated factors and GIS is used to assess and map the groundwater vulnerability to pollution in Haerbin. (Correlated factors are depth of the water - table, net recharge, aquifer media, soil media, topography, impact of the unsaturated zone and hydraulic conductivity of aquifer. The ground-water vulnerability map is particularly useful for land - use, environmental protection, ground water protection and decision - making purpose at all level of government.
