| 摘 要： | 在全国第二次水资源调查评价基础上,通过对比七大流域径流系列延长前后的变化情况,分析347个水文站点径流系列均值及特枯值的变化幅度,用以反映近10年各流域水文情势的变化情况。经分析,近10年天然来水总体偏枯,松辽、海河、黄河的设计径流呈现一定减小趋势,长江、淮河、太湖、珠江的设计径流变化趋势不显著。本次延长后的径流系列代表性总体较好,同时黄河流域还考虑近期下垫面对降雨径流关系影响,因此本次大多推荐七大流域延长后的设计径流成果,为开展全国第三次水资源调查评价提供一定的技术支撑。

| Abstract: | On the basis of the second water resources survey and evaluation in China, this paper analyzed the changes in therunoff series of the 347 hydrology stations and the variation of the low value by comparing the changes of the runoff series of theseven major basins, reflecting the changes in the hydrological situation of the basins in the last 10 years. The natural runoff isgenerally partial, and the design runoff of the Songliao River, Haihe River and Yellow River have been reduced, and the changetrend of the runoff in the Yangtze River, Huaihe River, Taihu Lake and Pearl River are not significant in the last 10 years. Afterthe extension, the representative of the runoff series is better, and the impact of underlying surface on rainfall-runoff relationshiphas be considered for the Yellow River Basin. |
