摘　　要：河道植物是河流生态系统的重要组成部分,其形态和生理生态对流域水文过程产生重要影响。形态对水文过程的影响主要表现为阻流、导流和截流三个方面。生理生态方面,可以分为河道植物吸水、含水和蒸腾耗水等环节。在分析这些方面研究进展的基础上,认为需要对不同种类河道植物的水文效应机理进行试验研究,才能对不同植物群落在较大尺度上对水循环过程的影响有整体把握,并需要考虑河道自身形态特点。The vegetations in rivercourse are the very important composition of the ecologic system of river. Its morphology, physilogy and ecology will produce very important effect to the hy- drologic process. The impact of morphology to hydrologic process major exhibited three aspects as resisting flow, diverting flow and harvesting flow. The impacts of physiology and ecology can be divided water uptake, storage and evapotranspiration. Based on analyzing the research progress, some mechanism effects of particular plants should be studied to grasp the influence of vegetation community to larger scale water cycling and the morphology of river should be taken into accout.
