摘　　要：文中在分析松花江流域河湖水系连通性现状的基础上,分别从纵向连通性、横向连通性和垂向连通性角度,采取定性、定量相结合的方式,分析了河湖连通性对水环境、鱼类生境、泡沼湿地面积以及地下水的影响。揭示了较差的河湖水系连通性是导致水质变差、部分洄游性鱼类资源量下降、泡沼湿地萎缩、地下水位下降的影响因素之一。Based on the present situation analysis of river and lake connectivity for Songhuajiang river basin, the paper analyzes the effect of river and lake connectivity on water environment, fish habitant, wetland area and groundwater through the combination mode of quantitative and qualitative from the point of view of the longitudinal connectivity, the transverse connectivity and the vertical connectivity. The result shows the poor connectivity of river and lake is one of the factors that lead to poor water quality, the decline of some migratory fish resources, the shrinking of marshes and the decline of groundwater level.
