中文摘要： 太原市是严重缺水的城市之一。为了恢复被长期过量开采而破坏的地下水资源，兴建了引黄入晋工程通过汾河天然河道每年向太原市输送黄河水3.2亿m3以满足用水需求。近年来黄河出现污染，查明调入的黄河水对受水区水环境的影响十分迫切。本研究以汾河引黄河段为典型区域，综合水文观测、同位素水文学，水文地球化学、统计分析以及数值模型模拟等多种研究方法，分析河水和地下水中离子含量、2H和18O组成、有机物（TOC、DOC、UV254和环境激素DBP）分布，研究河水与地下水水量交换模式，探讨不同自然地理环境下饱和/非饱和渗水、河岸入渗调蓄等情形地下水水化学变化和污染物运移问题，并讨论引水活动的影响。本研究将揭示引黄入晋工程调水对汾河受水区水环境的影响，对太原地区水资源保护有重要意义，有助于加深对人类活动影响下流域水循环和水环境问题的理解。

英文摘要： Taiyuan is one of the most water-shortage cities in China. For recovering the destroyed groundwater resource, the water transfer project from the Yellow River to Taiyuan had been established, annually transfering 320 million t water. Recently, the Yellow River was polluted that makes the emergency of illuminating the impacts of transferred water to water environment in the intake area. The intake area of the Fen River is focused in the research. Hydrological measurements, isotope hydrology and hydrogeochemistry methods, statistical analyses and models will be employed. Ion contents, 2H/18O compositions, organic materials (TOC, DOC, UV254 and DBP)distribution will be decided. The interaction between stream and aquifer will be studied. In distinct physical geography settings, the hydrological processes, such as saturated/unsaturated infiltration and bank infiltration, and pollutants migration will be discussed in deep. Further, the impact of water transfer on those issues will be analyzed. The research will discover the influences of the project on the water environment of the Fen River intake area. It is significant for water resource protection in Taiyuan and would be helpful to improve the understanding of the issue relating to the impacts of human activities on water cycle and water environment in a basin.
