摘　　要：地表水资源量的变化是随着补给源补给量的变化而变化的 ,人类活动可以改变地表水的补给源。解放以来 ,西北地区人口不断增加 ,经济不断发展 ,人类活动影响强烈 ,尤其是大面积的垦荒、大规模兴建水利设施和进行水土保持 ,以及植树种草等 ,对地表径流情势已经产生了较大影响。从问题严重性看 。Surface water resources is changed with water supply sources, but water supply sources can be changed by human activity. Since 1949, surface water runoff have been changed clearly in northwest China, because of violent human activity, such as increasing population and developing economy, especially reclaiming much land, building many water projects, conserving of soil and water, and tree planting and grass growing. Human activity have great influence on region distribution and time course of surface water resource.
