| 摘 要： | 径流的年内分配直接决定着水利工程建设的规模及水利工程的运用方式。在系统分析表达年内分配不均匀程度指标的基础上,采用1970~2005年实测旬及月径流资料对汾河水库上游流域主要控制站的径流年内分配不均匀性进行了分析。分析结果表明:旬集中度更能很好地反映径流的年内分配不均匀程度;静乐站的年内分配比上静游站径流年内分配不均匀性大,年内变化幅度也大;1998年前静乐站和上静游站的年内分配程度规律相似,1998年后静乐站径流年内分配不均匀程度不同于上静游站。

| Abstract: | The scale of the hydraulic engineering works and its operation were decided by the annual runoff distribution.The annual runoff distribution in the upstream of the Fenhe Reservoir was analyzed based on the analysis of the Non-uniformity indexes adapted decadal and monthly data during 1970~2005.The results showed that non-uniformity could be reflected well by the decadal concentration degree.The non-uniformity of the Jingle station was larger than that of the Shangjingyou station,and its change scale in Jing... |
