中文摘要:
      流域洪水过程受降雨、流域下垫面等多种因素的综合影响,其中人类活动对流域出口洪水过程的影响在近些年越来越明显。选择第二松花江丰满水库以上为典型流域,在调查资料整理和分析的基础上,利用三水源新安江模型,结合人类活动对洪水的主要影响方式,建立了人类活动与模型参数之间的相关关系,依据参数物理意义对WM,B进行改进,并进行场次洪水模拟。通过结果对比分析可知,该方法模拟精度较高,模拟结果能合理反映人类活动对实际洪水过程的影响,可以为该流域水利工程建设与洪水预报提供参考,对其他流域洪水的研究也具有借鉴意义。
英文摘要:
      Basin flood process is affected by several factors such as rainfall and the underlying surface of watershed, especially human activities have significant impacts on the flood process in the outlet of river basin in recent years. In this study, the upstream basin of the Fengman reservoir in the second Songhua River was selected to perform flood simulation using the Xinanjiang model based on the analysis of survey data The relationships between human activities and model parameters were established in consideration of the impacts of human activities on flood process, and WM and B were improved according to the physical significance of the parameters. The results showed that the method has high simulation accuracy and can reasonably reflect the effects of human activities on the actual flood process, which can provide references for the construction of water conservancy project and flood prediction.
