Study On Urban-Rural Spatial Optimization Of Kaiyuan City Based On Symbiosis Theory

In the context of a slow global economic growth,China's sustained and healthy economic development is inseparable from the new urbanization.As the most basic and important administrative unit,the county area is the key and important growth point of the new urbanization.It is of great significance to the healthy development of the county(city)region.It is necessary to construct a new type of urban-rural relationship with new thinking.Kaiyuan as a typical county-level city in Liaoning Province,both plains and mountains,but also the development of Harbin economic and industrial belt to an important node in the city,rich in resources,diverse types of regional research covers a wide area,Urban and rural spatial layout research,to explore the new form of urban and rural space development path and organizational model,the overall county(city)of urban and rural development has a certain representative and guiding significance.The main content of the article is divided into four parts:The first part analyzes the constitution of symbiosis system and the related analysis methods from biology point of view.Then,on the basis of symbiosis theory,this paper focuses on the connotation of urban-rural spatial development under the symbiosis theory and the guiding role of urban-rural spatial development.In the second part,the urban-rural space of Kaoyuan is divided into three parts:the urban-rural spatial development of Kaiyuan City,the urban space,the agricultural space and the ecological space by means of on-the-spot investigation and data collection.Expounds and analyzes the function and development characteristics of various types of space.The third part analyzes the symbiosis problem between the three basic spatial units based on the current situation and the spatial analysis function of arcgis.It mainly analyzes the symbiosis problem between the urban and rural settlements,the symbiosis between the industries,The symbiosis between industrial space and ecological space,the problem of rural settlements and ecological space.For the follow-up to optimize the direction of urban and rural space and lay the foundation for the content.Urban and rural space is the carrier of new urbanization,and the advantages and disadvantages of urban and rural spatial optimization strategy of Kaiyuan City involve the effect of urban and rural spatial organization and implementation.The fourth part analyzes the motive mechanism of the spatial evolution of urban and rural areas,and puts forward the optimization model of urban and rural residential area,primary,secondary and tertiary industries,ecological environment and traffic space.According to the space development model,spatial organization optimization layout is proposed,which includes spatial optimization of urban and rural residential area,industrial space optimization and ecological space optimization.And build a global market control of the development of the city.
