中文摘要	为揭示干旱区库坝工程对车尔臣河中下游地下水位的影响,基于水文地质、气候变化以及当地灌溉等相关数据,应用GMS构建地下水模型,对地下水流场的变化进行了模拟预测研究。结果表明:①车尔臣河流域模拟区地下水多年均衡量为1 170.74*10~4 m~3,表现为微弱正均衡,多年地下水水位上升约13 mm,地下水水位总体呈现微弱上升趋势;②从整个区域角度而言,建坝前后地下水流场趋势并没有出现显著变化,但是局部地区流场变化较明显,主要是灌区和下游入湖区段,受影响的地下水位变幅为0.4~0.8 m,而南北两侧可能受影响宽度范围约1 km。
英文摘要	In order to reveal the impacts of dams and reservoir works located in the arid zones on the groundwater level of the middle and lower reaches of the Qarqan River, with GMS applied to the groundwater modeling, a model for prediction studies of the changes in the groundwater flow field was made on the basis of the related data, such as hydrogeology, climate change and irrigation in local areas. The analysis results indicate that firstly, the equilibrium amount of the groundwater in the simulated area of the Qarqan River has been 1170.74*10~4 m~3 for years, showing slight proper equilibrium. The rising height of the groundwater has been up to 13 mm for years, and the groundwater has generally demonstrated upgrade tendency; and secondly, from the perspective of the whole region, great changes of groundwater flow field trend have not appeared since the dam was constructed. However, remarkable changes of flow field in the local areas have occurred. The main areas are irrigated ones and the downstream sub-basin of the lakes. The fluctuation of the affected underground water level is up to 0.4 ~0.8 m, whereas the likely affected width range close to the north and south sides of the Qargan River is about 1 km.
