基于浑河与太子河上游1998—2007年北口前站和南甸峪站水文数据以及清原、新宾和本溪县气象站点同期气象数据,应用DHSVM分布式水文模型模拟浑太流域的水文过程,验证模型的科学适用性,并提供最敏感模型参数的参考值.结果表明:浑河源区月径流模拟的Nash-Suttclife系数(E值)在率定期(1998—2002年)和验证期(2003—2007年)分别达到0.9675和0.8957,较好重现了研究区的月径流过程.太子河上游流域的年、月径流模拟值的E值均大于0.6,说明模型在浑太流域有较好的适用性、率定的参数方案有良好的可靠性.本文为无站点观测资料的流域水文研究建立了一个坚实的框架,并构建了合理的参数方案.
Based on the meteorological data of North Front Station and Nandian Yu Station from 1998 to 2007 and the meteorological data of Qingyuan, Xinbin and Benxi meteorological stations in the upper reaches of Hunhe and Taizi rivers, the DHSVM distributed hydrological model was used to simulate the hydrological process in the Hun-Hun basin. The results show that the Nash-Suttclife coefficient (E value) of monthly runoff simulation in the Hunhe River source region has a significant positive correlation between the rate of periodic (1998-2002) and the validation period (2003-2007) Year) reached 0.9675 and 0.8957, respectively, which reflected the monthly runoff of the study area better.The E values of the annual and monthly runoff simulated values in the upper reaches of the Taizi River are all greater than 0.6, which shows that the model has good applicability in the muddy terrain , The calibrated parameter scheme has good reliability.This paper establishes a solid framework for the basin hydrological research without station observation data and constructs a reasonable parameter scheme.
