摘　　要：受人类活动的影响,海河流域下垫面条件发生了较大变化,造成产汇流参数发生了巨大变化,流域产汇流规律发生一定程度的改变,而产汇流参数变化直接影响着洪水计算结果。通过产汇流参数变化对洪水计算的影响分析,找出其对洪水计算的影响规律,对海河流域洪水分析计算有一定参考价值。Affected by human activities, the underlying surface conditions has great changes in Haihe river watershed, it has a variation of runoff yield and concentration parameters, and change the rule of runoff yield and concentration in a certain degree, the variation of runoff yield and concentration parameters has a direct impact on the results of flood calculation. Based on the effect analysis, to investigate the influence of variation of runoff yield and concentration parameters on the flood calculation, have certain reference value to the flood analysis and calculation of Haihe river basin.
