摘　　要：湿地水文研究是湿地科学的重要分支,是进行湿地保护和恢复的基础。对于河边湿地这一特殊的湿地类型来说,其水文特征在受到天然降水影响的同时,河道对其水文特征的影响往往更为重要。本文以西安泾渭河边湿地为例,用MODFLOW模拟研究了渭河对泾渭河边湿地水文的影响,对泾渭湿地在平水年中各月的水平衡要素以及不同水文年的水平衡要素进行了分析。结果表明,年内各月的水平衡要素所占比例发生较大的变化时,不同水文年的年水平衡组成比例也发生了很大的变化。Wetland hydrological study is an important branch of wetland science and the foundation of wetland protection and restoration. For a special river wetlands, the hydrological charac- teristics is affected by natural precipitation. However the river impacts to hydrology is often more important. To take the Xi＇an Jing-Wei River wetland as an example, this paper simulated the impact of Weihe River to the hydrology of the wetland of Jing-Wei River by the MODFLOW, the water balance for every month in the ordinary hydrological year and different hydrological years were analyzed. The results shown that the proportion of the monthly elements of the water balance occars large change also the composition of the water balance will be changed a lot in different hydrological years.
