| 摘 要： | 以白洋淀水文数据为基础，采用敏感系数法，分析了气候变化、人工取用水及蒸渗过程改变对入淀水量变化的影响。在研究时段内，湿地入淀水量、流域降水量及潜在蒸散发量都呈下降趋势，其中入淀水量下降尤为明显。气候变化、人工取用水及蒸渗过程改变对入淀水量变化的影响分别为25.1%、57.53%和17.4%，而人类活动整体对入淀水量影响达到了74.9%，因此人类活动是入淀水量减少的主要原因。

| Abstract: | Based on the hydrological data of Baiyangdain Wetland，the impacts from the climate change，the artificial water intake，the change of evaporation-seepage process，etc. on the variation of the inflow to Baiyangdian Wetland are analyzed herein with the sensitivity coefficient method. Within the study period of time，all the inflow to the wetland，the precipitation in the basin and the potential evapotranspiration therein show the trends of decline，among which the decline of the inflow to the wetland is quite significant. The impacts from the climate change，the artificial water intake and the change of the evaporation-seepage process on the variation of the inflow to the wetland are 25.1%，57.53% and 17.4% respectively，moreover，the impact of the integration of all the human activities on the inflow to the wetland reaches to 74.9%，and then the human activities are the main factors of the decline of the inflow to the wetland. |
