摘　　要：利用2016年黄河上游十大孔兑区域及中游河龙区间305个雨量站的逐日降水量资料,将降水分为中雨、大雨、暴雨和大暴雨等量级,分析了2016年河龙区间及十大孔兑年降水量和不同量级降水量的空间分布特征,以及与多年平均降水量的对比情况。结果表明:①2016年研究区面平均降水量为622.1 mm,为1966年以来最大年降水量;汛期降水量、中雨、暴雨、大暴雨雨量分别为454.7、452.5、131.5、53.4 mm,均为1966年以来最大值;大雨雨量为249.8 mm,为仅次于2013年的第二大值。②2016年研究区年降水量、汛期降水量以及不同量级降雨量均较多年均值偏丰,其中量级降水量偏丰程度更大。③降水量较大的区域集中在河龙区间中北部,大暴雨主要集中在秃尾河、佳芦河及其黄河对岸的区域,以及吴堡水文站附近区域和十大孔兑中的西柳沟和罕台川。Based on the daily precipitation of 305 stations in the ten tributaries and the region from Hekouzhen to Longmen of the middle Yellow River basin in 2016 , the spatial variations of annual precipitation and different level precipitation were analyzed and compared the annual precipitation and different level precipitations with the average values from 1966 to 2016. The results show that a ) the annual precipitation of the study area in 2016 is 622.1 mm and this is the largest annual precipitation since 1966. Rainfall in flood season , moderate rain , rainstorm and heavy rainstorm rainfall are 454.7mm , 452.5mm , 131.5mm and 53.4mm respectively , which are all exceeding the maximum of historical observations since 1966. The heavy rainfall is 249.8mm , which is the second largest value. b ) All of the annual precipitation , flood season precipitation and different level precipitations in the study area in 2016 are larger than that of the average values from 1966 to 2012 and the different level precipitations are more abundant. c ) Area with large amount of precipitation is mainly in the middle north region from Hekouzhen to Longmen , heavy rainstorm is mainly concentrated in the areas of Tuwei River , Jialu River and the other side of the Yellow River , as well as the regions near Wubu Hydrological Station and Xiliugou and Hantaichuan in the Upper Yellow River basin.
