摘要利用GRACE卫星2003-2008年逐月重力场资料，经高斯滤波，得到了唐乃海盆地的蓄水量变化量。结合各区域气象站同期月降水量资料，分析了唐乃海流域近6年来蓄水量变化的时空变化趋势。结果表明，唐乃海流域蓄水变化的空间分布具有明显的差异性，西部地区蓄水变化多于东部地区；蓄水变化具有明显的季节变化特征，且与降水变化过程一致，研究区蓄水变化呈逐年增大趋势。2003年至2008年，唐乃海流域蓄水变化总体呈上升趋势，平均变化速度为0.5 mm/月，蓄水变化减少约6.1×106m~3。
Abstract.The amount of water storage change in Tangnaihai basin is obtained by using monthly gravity field data, which is derived from GRACE satellite between 2003 and 2008, with Gaussian filter. Combined with the same time period monthly precipitation data of the regional meteorological stations, we analysis spatial-temporal variation trend of water storge change in Tangnaihai basin for nearly 6 years. Results show that the spatial distribution of water storge change in Tangnaihai basin has obvious difference,water storge change is more in west than in east area.Water storge change has obviously seasonal variation change, and it has the same process with precipitation.The trend of water storge change increase in annual in study area. Water storge change increased from 2003 to 2008 in totally in Tangnaihai basin.The average rate is 0.5 mm/month,and water storge change reduced about 6.1*106 m3.
