黄河口冲淤演变动力学仿真模型构建

Dynamics Simulation Model of Scour and Silting Evolution in the Yellow River Estuary

尝试将系统动力学方法用于黄河口冲淤演变研究,对黄河口实测资料进行处理,分析了冲淤演变影响因素,确定了冲淤演变系统的边界。引入辅助中间变量,分析河口冲淤演变系统动力学因果关系;并引入水平变量、流速变量、信息流等因素,构造更加深入的系统行为关系,从而更加完整、具体地描述系统构成、系统行为和系统元素相互作用机制的全貌。

This paper tries to apply system dynamics to study the erosion and deposition evolution of Yellow River Mouth.On the basis of the analysis of the actual measurement data of Yellow River Mouth,the influencing factors of the erosion are analyzed,and boundaries of the system are made.By using assistant intermediate variable,causalities of the system are analyzed;and by using factors of level variable,velocity variables and information flow,a clear system behavior relationship is made,and the interaction mechanism of the system structure,system behavior and system elements are described integrately and concretely.
