中文摘要	利用黑河流域9个气象台站降水数据,在不同时间尺度和空间分布上分析了2008-2011年TRMM多卫星降水数据(TMPA 3B43)在黑河流域的适用性.结果表明:用TMPA估测的年降水量在黑河流域平均高估27.3%,对上游降水量大的山区估测相对好于降水稀少的黑河下游地区;TMPA与气象站降水量的拟合优度夏季(R~2=0.851)高于冬季(R~2=0.332);TMPA可以较好反映各测站降水量年变化、月变化趋势,用TMPA估测的黑河流域平均年降水量变化趋势为30mm·(10a)~(-1).黑河流域年降水量体现出随海拔高度的递增规律(11.1mm·(100m)~(-1))、从东向西降水量逐渐减少的分布以及最大降水高度带出现在上游偏东地区(海拔2 800~4 900m).
英文摘要	The Tropical Rainfall Measuring Mission (TRMM) Multi-Satellite Precipitation Analysis (TMPA)3B43 product is evaluated using the gauge precipitations from 9 weather stations in Heihe River basin at different time steps and spatial distribution.It is found that TMPA-3B43performing result at time step and spatial scale is not so satisfactory.Regional average annual precipitation evaluated by TMPA is overvalued by 27.3%. At the same temporal resolution,in the humid region, such as the upstream of the Heihe River, TMPA performs better than that in the arid regiones, such as downstream of the river.Specially, during summer the overvalued precipitation is obvious in the downstream of the river.The goodness of fit between TMPA precipitation and observed precipitation is better in summer (R~2 = 0.851)than in winter(R~2=0.332).TMPA can express annual and month variation trends of precipitation well.Regional average linear trends of annual mean precipitation is estimated to be 30 mm·(10a)~(-1) from TMPA.In addition,TMPA estimated data can express the spatial distribution of precipitation in the basin.Annual precipitation increases with height with a rate of 11.1 mm·(100m~(-1)).Precipitation decreases from east to west and the zone of maximum precipitation lies between 2800to 4 900ma.s.l.
