摘　　要：利用2007年7月淮河流域常规站、自动雨量站和自动气象站逐日降雨资料,选取不同的方法,计算淮河流域15个子单元的面雨量实况,并对结果进行了对比分析。结果表明:所采取的泰森多边形法和算术平均法计算结果相差不大。同时,将自动气象站、自动雨量站以及常规站点进行合成,用合成后的站点雨量计算的面雨量与常规站计算结果进行对比,进一步分析站点密度及站点分布对流域面雨量计算的影响,结果表明不同雨量资料的计算结果存在差别。Based on the daily rainfall data of Conventional Weather Station,Automatic Rainfall Station, and Automatic Weather Station in Huaihe River Basin in July 2007 ,area rainfall of 15 sub-units in Huaihe River Basin were calculated, and made a comparative analysis of their corre- sponding results. The results showed that it was little difference between two methods. Meanwhile, Auto Weather Station, Automatic Rainfall Station as well as Conventional Weather Station were synthesized into a new rainfall data. Then the area rainfall was calculated by the new rainfall data and compared with the area rainfall by conventional weather station data. Effects of density and distribution of the station on calculating the area rainfall in Huaihe River Basin were analyzed. It turned out that there is a significant difference of the calculating results using different rainfall data.
