内蒙古阿拉善盟查汗套海滩生态环境治理建设区地下水资源评价与研究

STUDY AND EVALUATION OF GROUNDWATER RESOURCES OF CHAHANTAOHAI ECOLOGICAL ENVIRONMENT IMPROVEMENT AREA OF ALSAN LEAGUE

查汗套海滩生态建设区不具备引黄灌溉、天然排水条件。开采地下水 ,以抽代排 ,把地下水位降到临界深度以下 ,防止盐渍化。以此为目标 ,评价地下水流系统中的水资源量 ,允许开采量 。

There are no natural conditions to divert water from Yellow River to chahantaohai ecological envirconment improvement area of alsan league for irrigation and there is no natural drainage conditions in the areas.To control groundwater critical depth to prevent the soil from salinity depends on the pumping groundwater.To achieve this objective,the groundwater resource is evaluated,the permitted pumping discharge quantity of groundwater has been calculated,which provided the bases fro the improvement of the area.
