摘要
由于人类活动改变了流域下垫面条件,导致流域入渗、蒸散发、径流等水文要素发生一定的变化,从而引起流域产汇流的变化。针对以上情况,选用紫荆关以上流域历史暴雨洪水资料,分析了流域下垫面变化对流域产汇流影响,为今后洪水预报和水资源分析评价提供资料基础。
Human behavior changed condition of basin cushion, causing specified alternation of the hydrological key elements as infiltration, evaporation, runoff and so on,which induced the change of runoff yield ＆ flow. In view of the foregoing situation,we chose torrential rain flood water data of Zijingguan basin, analyzed the impact on runoff yield ＆ flow by basin cushion change, which would provide a data base for flood forecasting and water resource evaluating.
