摘要
针对石羊河下游民勤绿洲地下水资源严重超采,地下水位持续快速下降的现状,以及所引起的生态环境效应,提出了恢复地下水位生态需水量的概念和计算方法,并且预测出2000—2019各年恢复地下水位生态需水量。根据民勤绿洲的具体特点提出了恢复持续下降的地下水位、改善和恢复生态环境的一些可行措施。
For the present situation of seriously over-exploited groundwater resources and the rapid declining level of groundwater in the Minqin Oasis in the lower reach of Shiyang river, as well as the induced effects of ecology and environment, the concept and calculation method of ecological water demand for restoration level of groundwater were provided, then ecological water demand for restoration level of groundwater from 2000 to 2019 is forecasted. Some applicable measures which can restore the level of groundwater and ecological environment were developed according to the features of the oasis,
