摘要
文章利用DRASTIC模型,模型包括地下水埋深(D)、含水层净补给量(R)、含水层介质类型(A)、土壤类型(S)、地形坡度(T)、包气带岩性(I)和含水层的导水系数(C)7个因子,对广西区潜水防污性能进行评价。结果表明:潜水含水层防污性能较好区总面积1.55×10^4 km^2,占全区面积的6.54%;潜水含水层防污性能中等区总面积17.31×10^4 km^2,占全区面积的73.04%;潜水含水层防污性能较差区总面积4.84×10^4 km^2,占全区面积的20.42%。其成果可为广西区地下水污染防治和生态文明建设、环境保护等提供指导和借鉴。
This paper used DRASTIC model,which includes 7 factors:groundwater depth(D),net aquifer recharge(R),aquifer medium type(A),soil type(S),topographic slope(T),gas encasement lithology(I)and aquifer conductivity coefficient(C),to evaluate the diving antifouling performance of the western district.The results showed that the total area of the subsurface aquifer with good antifouling performance was 1.55×10^4 km^2,accounting for 6.54%of the total area.The total area of the medium area with antifouling performance of the submerged aquifer is 17.31×10^4 km^2,accounting for 73.04% of the total area.The total area of the subsurface aquifer with poor antifouling performance is 4.84×1^04 km^2,accounting for 20.42% of the total area.The results can provide guidance and reference for groundwater pollution prevention and control,ecological civilization construction and environmental protection in Guangxi.
