摘　　要：2003年上半年,黄河流域主要来水区(站)来水量较常年偏少40%～70%,为有资料记录以来的最小值。进入汛期以后,黄河流域大部分地区降水量持续偏多,其中泾河、渭河和三门峡—花园口区间7～10月降水量较常年偏多60%～70%;9～11月渭河华县站、洛河黑石关站和沁河武陟站来水量较常年偏多1～6倍。7月30日北干流府谷站发生该站有实测资料记载以来最大洪水;8月下旬到10月上旬,渭河连续发生6次洪水,咸阳、临潼、华县等站出现历史最高洪水位;洛河部分站也出现有实测资料记载以来最大洪水。黄河下游小浪底—利津河段全年约冲刷泥沙2.55亿t。The coming water in key regions (stations) in the Yellow River basin before June 2003 is 40%～70% less than the normal year, which is the minimum value since recording. While in the flood season, the rainfall in the majority regions of the Yellow River basin is continuously more than the normal, of which, the rainfall of Jinghe River, Weihe River and Sanmenxia-Huayuankou reach in July-October period is 70%～90% more than the normal, the coming water at Huaxian Station on the Weihe River, Heishiguan Station on the Yiluo River and Wuzhi Station on the Qinhe River in September-November period is 1 ～ 6 times more than the normal. On July 30, the maximum flood occurred at Fugu Station on the north main channel since the observed data. In the period from late August to early October, there are 6 floods continuously happened in the Weihe River and historical maximum flood level has been reached at Xianyang, Lintong and Huaxian. Some stations on the Yiluo River also have the maximum flood since the observed data. The river section of Xiaolangdi-Lijin has been eroded 180 million tons.
