伊犁河谷西部平原区地表水与地下水转化关系研究

地表水与地下水资源是区域水资源的重要组成部分，查明地表水与地下水的相互转化关系，对于揭示水资源形成机制和促进水资源合理开发利用具有重要意义. 在综合分析伊犁河谷西部平原区地质和水文地质条件的基础上，选择伊犁河干流及其典型支流，分析了河水及周边地区地下水氢、氧稳定同位素的组成和空间分布特征，揭示了地下水补给来源以及地表水–地下水之间的密切关系，并利用222Rn建立相关质量均衡模型，计算了伊犁河与地下水间的相互转化量. 结果表明:伊犁河北侧平原区地下水径流主要受控于地形和岩性；南侧平原区的地下水径流主要受控于新构造运动，且地下水与地表水都进行了多次转化. 研究结果可为伊犁河谷西部平原区地下水的合理开发利用提供依据. 

Surface water-groundwater interactions in the western plain of the Ili Valley

Both surface water and groundwater resources are important components of regional water resources. Interaction between surface water and groundwater is an important link in the formation of water resources, such interactions are also important in the rational development and utilization of water resources. Comprehensive analysis of geological and hydrogeological conditions, choice of typical tributaries, analysis of hydrogen and oxygen stable isotopic composition and spatial distribution characteristics revealed recharge routes of groundwater sources and close relationship between surface water and groundwater. Mutual transformation between Ili River and groundwater was calculated using 222Rn tracing. Groundwater runoff in north plain of Ili River was found to be mainly controlled by topography and lithology, while groundwater runoff in south plain of Ili River was found to be controlled by neotectonics movements, groundwater having frequent multiple transformations with surface water. Rational exploitation and utilization of groundwater in this area could be realized.
