| 摘 要： | 采用IHA方法分析了雅砻江流域调水区河流调水前的水文资料,提取对基本生态条件维护具有重要意义的月基流量作为特征流量,采用Tennant法评价基流量对生态的有利程度,并对比分析南水北调西线一期调水工程实施后水文站月平均流量对生态的有利程度,间接推求坝址下游近坝段特征基流量,探究调水后月均流量对生态的有利程度,为进一步研究生态调度提供参考.结果表明:随着沿程流量的恢复,甘孜、道孚水文站河段水量能恢复到维持较好的生态水平,朱巴站距离引水坝址相对较近,调水后月平均流量的生态有利程度略差.坝址下游河段调水后月平均流量对生态有利程度明显下降,3个坝址河段5-7月和11月均为"差".

| Abstract: | This paper uses IHA method to analyze the pre-project discharge data in the Yalongjiang river's transfer area;then takes the monthly low flows as the characteristic flows,which is important to maintain the basic ecological river system;and uses Tennant method to assess them.With taking the characteristic flow as a reference,the paper concerns the advantage to the ecosystem of the monthly average flows post-project in the stations reaches.It still calculates indirectly the monthly low flows downstream the da... |
