摘　　要：以衡水湖及周边24个雨量站1974年-2010年的降水资料为基础,分别计算了湖区、10km半径影响区、10～20km环形影响区、20～30km环形影响区的平均降水量,据此对衡水湖湿地的降水影响规律进行了分析,并基于降水形成机理探寻其变化的主要原因。研究结果表明,衡水湖湿地由近及远降水量呈明显递减趋势,反映了衡水湖湿地对周边区域气候具有调节作用。In this paper, the precipitation data of Hengshui Lake and 24 nearby rainfall stations from 1974 to 2010 were used to calculate the average precipitation of the Hengshui Lake District, 10-km radius affected zone, 10- to 20-kin circular affected zone,and 20- to30-km circular affected zone. The effects of the wetland of Hengshui Lake on precipitation were analyzed, and the main reasons were investigated based on the formation mechanism of precipitation. The result showed that the precipitation decreases from near to distant distance of the Hengshui Lake Wetland, indicating the adjustment effects of the wetland on the climate of surrounding area.
