| 摘 要： | 通过系统分析张掖城市湿地水文地质条件,采用DRASTIC法,选取了地下水位埋深、净补给量、含水层介质、土壤介质、地形、包气带介质和渗透系数共七项影响因子对张掖城市湿地城市区地下水防污性进行了评价。结果表明,张掖城市湿地地下水防污性较好地带主要分布在研究区南部新墩镇——二十里铺一带地下水深埋区,水位埋深一般大于10 m,...

| Abstract: | The article is based on analysis on evaluation of the soil resistance on wetland groundwater in the urban area of Zhangye,using DRASTIC and taking seven influencing factors including depth of groundwater lever,net recharge,aquifer medium,soil medium,terrain,aeration zone medium and osmotic coefficient to evaluate the pollution of groundwater.The wetland groundwater with the best soil resistance mainly distribute on the southern part of the studied area,20 mile village of Xindun town.The groundwater lever of this distribution is much deeper,usually over 10m.The litho-logical characters of aeration zone are mainly sand loam and gravel.The evaluation of groundwater soil resistance must base on the sufficient geology and hydrogeololgy data.The classification of evaluation factors must base on reality and emphasize the relativity of the factors. |
