腾格里沙漠邓马营湖开发区地下水资源现状评价

Present Situation of Groundwater Resources in The Desert Deng Ma Ying Lake Development Zone Evaluation

在充分研究邓马营湖开发区已有水文地质成果的基础上,通过开展水文地质调查、水文物探、地下水动态观测及抽水试验等工作,基本查明了区内地层结构、地质构造、基底形态、地下水的埋藏与分布及补径排条件,进行了地下水资源计算和允许开采量评价,得出允许开采量为4317.61万m3/a,占地下水天然资源量为87.05%,占地下水总补给量的78.07%,不会造成区域地下水位下降,将其作为评价区允许开采量是合理可行的。为邓马营湖开发区的农业开发与农田供水提供了水文地质依据。

The paper is based on the existing fully study Deng Ma Ying Lake Development Zone,hydrological and geological re-sults, supplemented by the hydrogeological survey, hydrogeology, groundwater dynamic observation and pumping test, the basic i-dentification of the layer structure, geological structure, groundwater buried basement morphology, and distribution and recharge runoff discharge conditions, the groundwater resources calculation and evaluation of allowable exploitation quantity, provides the hydrological geological basis for Deng Ma Ying Lake Development Zone, agricultural development and agricultural water supply.
