| 摘 要： | 长江流域水文成果复核选取了48个水文站点作为研究对象,考虑站点上游已建具有较强调节能力的大型水库调蓄影响,对径流、洪水进行还原分析计算以保证系列的一致性,并对径流、洪水设计成果的变化进行对比分析。径流成果分析表明,延长系列后干支流主要控制站点的径流成果较为稳定,多年平均年径流量和各站点20%、50%和75%频率年径流设计值的相对变化均在5%以内;洪水成果分析表明,延长洪水系列后的百年一遇设计洪水成果与前期不同阶段采用成果相比变化不大,基本均在4%以内。

| Abstract: | 48 hydrological sites in the Yangtze River Basin were selected to recheck the runoff and design flood. Considering theinfluence of the large reservoirs with strong adjustment abilities in the upstream sites, the reduction calculation and analysis ofrunoff and flood data were carried out to ensure the consistency of the series. Furthermore, a comparative analysis of runoff andflood design results were conducted. Runoff analysis shows that the runoff results of the main control sites in the Yangtze Riverbasin are relatively stable. The change of average annual runoff and 20%, 50% and 75% frequency annual design values of thesites are within 5%. Flood analysis shows that the design flood results with a 100 year return period change within 4% whencomparing with the previous results of different stages. |
