鄱阳湖流域1980-2008年降水量空间分布

基于鄱阳湖流域14个标准国家气象站的降雨资料，计算了该流域气象站点1980－2008年的年降雨量空间变化，并利用Arcgis软件结合空间反距离加权法完成了流域年降雨量的空间插值。所获取的矢量图像可用来分析鄱阳湖降雨量的空间差异及其年代变化，揭示湖泊流域洪旱涝灾害成因等。

Based on rainfall data from 14 standard national meteorological stations in the Poyang Lake Basin, this study calculated the spatial variations of annual rainfall at these stations within the basin for the period 1980–2008, and completed spatial interpolation of the basin's annual rainfall using ArcGIS software combined with the Inverse Distance Weighting (IDW) spatial interpolation method. The obtained vector imagery can be utilized to analyze the spatial differences and interannual variations of rainfall in the Poyang Lake region, and reveal the causes of flood, drought and waterlogging disasters in the lake basin, among other related research purposes.
