Study On Spatial Form And Formation Mechanism Of Flood Control In Historical Towns In The Yellow River Flood Plain

The Yellow River flood plain is a unique alluvial plain formed by the long-term desilting and flooding of the Yellow River.The special physical geography,social and cultural environment of this region has created a historical town with great characteristics.In the long-term process of resisting the flood of the Yellow River,these historical towns have formed a unique spatial form and have distinct flood control characteristics.Their flood control experience can be used as a reference for modern cities to solve the problem of waterlogging.However,with the rapid development of urbanization in recent years,some historical towns in the Yellow River flood plain have been ignored due to the low level of administrative division and small regional influence.The form of flood control has gradually declined or even disappeared,and the wisdom of flood control has also been buried.Therefore,it is urgent to protect the flood control spatial form of historical cities and towns in the Yellow River flood plain and tap the flood control wisdom.Taking the historical towns in the Yellow River flood plain as the research object,this paper first combs the types of flood control spatial forms of historical towns in the Yellow River flood plain from the aspects of water spatial structure,water location form and water landscape characteristics,extracts the three spatial morphological characteristics of these historical towns with regional characteristics:outer circle and inner side,outer high and inner low,and urban water dependence,and summarizes the four flood control systems of water avoidance,water barrier,water storage and drainage,flood storage,flood control Four flood control wisdom:flood diversion and flood discharge.Secondly,taking the influencing factors and dynamic composition as the starting point,this paper analyzes the influence of natural,social and cultural factors on the spatial form of flood control in historical cities and towns in the Yellow River flood plain,and obtains the dynamic mechanism model composed of driving force and remodeling force.Based on the above research,this paper summarizes the modern value of flood control spatial form of historical towns in the Yellow River flood plain,defines the protection content of flood control spatial form,puts forward the development path of historical towns,and provides suggestions for the future construction and development of historical towns in this area.Finally,by studying the spatial morphological characteristics and formation mechanism of flood control in Limin Town,this paper summarizes its flood control experience,so as to provide reference for modern urban flood control planning.By studying the spatial form and formation mechanism of flood control in historical towns in the Yellow River flood plain,this paper enriches the research content of historical towns in the Yellow River flood plain;Summarize the flood control system and flood control wisdom,which provides a reference for the prevention and control of modern urban waterlogging;Clarifying the modern value of flood control spatial form provides ideas for the protection and development of local historical towns.
