Abstract: There are many hydro projects in Fengman river basin. As human activity changed the runoff yield and concentration of the river basin, forecast accuracy decreased, which was bad for reservoir operation and flood prevention. Thus, investigation and research on influence of human activity were carried out, for better dam operation management and greater profit.

摘要： 丰满水库流域水利工程众多，人类活动对水库来水影响巨大。由于人类活动对流域产、汇流条件的改变，原水文预报模型精度下降，不利于流域正常水文预报工作的开展，严重影响了流域内水库防洪与兴利效益的发挥。为此，进行人类活动影响调查与研究，为考虑人类活动影响的洪水预报、水库运行调度工作打下基础。
