摘　　要：地下水是维持乌鲁木齐河流域社会经济发展和生态系统的最重要的水源,尤其是柴窝堡盆地因大量开采使得地下水水位下降、湖面萎缩,地下水系统动态特征发生了变化,所以研究区内地下水水流系统及其补径排关系对于深入研究盆地地下水流系统特征和合理开发利用地下水水资源能够提供重要的基础资料,尤其是对调整地下水资源的开采布局具有现实意义。本次研究主要以地质、水文地质背景资料为基础,结合地下水补给环境的差异,利用水化学和水的稳定同位素进行示踪研究,确定了柴窝堡盆地地下水的补给来源和排泄途径,区分出盆地排泄带不同点的补给区,包括东山、南山和西山补给区,对同一补给区又细分出不同的水流系统。Groundwater is essential to the development of socio-economy and ecosystem maintenance in rümqi River Catchment. However, heavy exploitation has resulted in decrease of groundwater level, and shrinking of lake size, and change of dynamic system of underground water especially in the Chaibu basin. So, research of underground water system and recharge relation not only provides an important basis for both understanding of underground water system in basin and reasonable application of underground water resources, but is of realistic significance for adjustment of underground water mining. Based on the geological and hydrogeolocial background and difference of recharge environments of underground water, this study defines the recharge source and discharge approach of underground water of the Chaiwobu basin using hydrochemcial and stable isotopic methods, and classifies the recharge reaches in the basin, including Dongshan, Nanshan and Xishan reaches, each of which is further subdivided into various current systems.
