Study On The Optimization Of The Spatial Structure Of Qingyuan County

In recent years,the optimization of spatial structure has become the upsurge of research in the field of planning,but the research on the spatial structure of the small towns in the mountain area is less and more quantitative,and the method of qualitative and quantitative is used to make the argument more convincing.And under the new background of the land space planning proposed by the Ministry of Natural Resources,the new requirements for the optimization of the spatial structure are put forward.The city of Qingyuan County,which is studied in this paper,is located in the mountainous area of Liaodong,and is a typical valley-shaped strip-shaped city.With the expansion of urban land,the spatial structure of the belt-like city is gradually presented.The Main Problems in the Development of Qingyuan County The environment is broken,the network of the green land is broken,the service of the central system is inefficient,the road organization is loose,the functional division is confused,and the like.In order to make the city of Qingyuan county more sustainable,this paper optimizes the urban spatial structure of Qingyuan County,and constructs the ecological intensive and high-efficient spatial structure,so as to guide the development of Qingyuan County.The general idea of this paper is to optimize the spatial structure of Qingyuan county according to the general route of putting forward problems-analyzing problems-solving problems,starting from the problems existing in Qingyuan county itself.According to the general line of putting forward problems,analyzing problems and solving problems,this paper optimizes the spatial structure of Qingyuan County.First of all,it is the stage at which the question is raised.The first chapter is the interpretation of the related background of spatial structure optimization,determines the research object and research method,clarifies the purpose and significance of the study,and determines the research content and research framework.The second chapter interprets the related concepts of spatial structure optimization and the review of research at home and abroad,which provides ideas for the spatial structure optimization of Qingyuan county.The second is to analyze the stage of the problem:the third chapter mainly analyzes the basic characteristics of the present situation,the external expansion characteristic,the internal construction character and the structure of the spatial structure of Qingyuan County,and has a preliminary cognition on the city space structure of Qingyuan County.The fourth chapter analyzes the elements of the spatial structure of Qingyuan County.Based on the analysis of the ecological environment and the distribution of the green space in the periphery of the Qingyuan county,the function division is analyzed mainly from the function structure and the function organization,and the road network structure is mainly analyzed from the distribution degree of the road and the collaborative relationship of the road,The use of space syntax to carry on the mining of the road problem.transportation of central system The development trend of the central system is judged by the analysis method of nuclear density.It lays a solid foundation for the next step to build ecological,intensive and efficient spatial structure.Finally,the stage of solving the problem:the fifth chapter first optimizes the constituent elements of Qingyuan County,and finally obtains the optimization scheme of the spatial structure of Qingyuan County.In the ecological network optimization,the ecological sensitivity evaluation method is used to delineate the ecological bottom line boundary,and the minimum path analysis method is used to construct the green space network in the county seat.In the aspect of functional partition,it is mainly optimized from two aspects:the decision of functional partition and the organization and guidance of functional partition.Build intensive functional partitions.In the aspect of road network structure,the road network structure is mainly optimized from two aspects:the overall connection of the road and the improvement of the regional organization,and the accessible road network structure is constructed.In the central system,the main structure The construction of urban center and the construction of district center are optimized to construct an efficient central system.In order to construct ecological,intensive and efficient spatial structure.The optimization spatial structure is used to guide the formation of the final optimization scheme of Qingyuan County,and the future construction and development of Qingyuan County are clarified.The sixth chapter mainly includes the research conclusion and the deficiency of this paper,and puts forward the prospect of the next stage research content.
