洪泽湖、骆马湖、南四湖径流丰枯遭遇分析

Analysis of Plentiful or Scanty Runoff Encountering in Hongze Lake, Luoma Lake and Nansihu Lake

依据洪泽湖、骆马湖、南四湖径流量资料，对湖泊历年不同时期径流进行丰枯评述，统计分析了洪泽湖、骆马湖、南四湖年径流、汛期径流、灌溉期径流、最枯期径流的丰、枯情况，提出了洪泽湖、骆马湖及洪泽湖、南四湖各种时期情况下水量丰或枯的遭遇频次并对洪泽湖、骆马湖、南四湖年及灌溉期的径流情况下连续丰水年组、枯水年组遭遇进行了剖析，最后对在东线南水北调工程优化调度中如何发挥长江。淮河水资源综合利用问题提出了建议。

Statistical frequencies of plentiful and scanty runoff of different time series, including annual runoff, runoff of flood period, dry and irrigation seasons, in Hongze Lake, Luoma Lake and Nansihu Lake were analyzed on the basis of historical runoff data. For all of these time series, estimated encountering frequencies of high-flow or low-flow in both Hongze Lake versus Luoma Lake and Hongze Lake versus Nansihu Lake were presented in this paper. Finally, statistical analysis of high-flow year group or low-flow year group and encounitering frequencies of annual and flood season runoff were studied. Some ideas of optimum development and comprehensive utilization of water resources in the Huaihe and Changjiang river basins were suggested for the East Route Project of South to North Water Transfer in China.
