松辽流域水文设计成果修订研究

Revision of Hydrological Design Results for Songliao Basin

受自然和人类活动影响,松辽流域水文成果发生较大变化。原有松辽流域径流系列至2000年,洪水系列仅至1998年,流域现有水文设计成果已经不能反映流域目前的水文情势。松辽水利委员会根据《松辽流域水文设计成果修订任务书》的要求,开展松辽流域水文设计成果修订工作,对松花江和辽河流域总面积78.23×10^4km^2范围内选定的63个水文站和工程点进行水文设计成果复核,将系列延长至2010年(其中黑龙江、松花江、浑河流域延长至2013年),分别进行设计径流及设计洪水成果复核,分析得出10多年来松辽流域水文成果的变化结论,提出推荐采用的水文成果,为流域水资源管理和防洪减灾提供技术依据。

Under the influence of natural and human activities,the hydrological results of the Songliao basin have greatly changed.The original runoff series in the Songliao Basin was made to the year of 2000 while the flood series was only made to the year of1998.The current hydrological design results of the basin have not been able to respond to the ongoing hydrological situation in the basin.The Songliao Water Resources Commission,in accordance with the requirements of the revision of the hydrological design results for the Songliao basin,has carried out the revision of the hydrological design results for the Songliao basin and rechecked the hydrological design results of the 63 hydrometry stations and engineering points selected in the Songliao Basins,and the series were extended to the year of 2010(the seires for the river basins of Heilongjiang,Songhuajiang and Hunjiang were extended to the year of 2013).The design runoff and design flood results were reviewed respectively,and the changes of hydrological results in the Songliao basin over the past 10 years were analyzed.
