Research On The Development Of The Spatial Of The County Town In Dongshan County

China has abundant marine resources and a large number of islands,including 12 islands and counties.The island's independent geographical environment,fragile ecological environment and limited resources are all problems that must be faced by its development.There are objective differences in the endowment and distribution of marine resources.The high dependence of island counties on marine resources makes their spatial development mainly oriented to the Gulf.At the same time,with the development of the urban development stage,the development and utilization of the marine resources will change gradually.The principle of profit making determines the objective law of the island county(District)gradually approaching to the advanced marine resources in the process of urban space development.Dongshan County is located in the southern part of Zhangzhou city of Fujian province.It is one of the 12 island counties in the country.It has a long history and cultural heritage and excellent marine resources.In recent years,with the implementation of the development strategy of the city group in the global tourism era,national new urbanization construction,Belt and Road Initiative strategy implementation and put forward the construction of ecological civilization of socialism,the CPC Zhangzhou Municipal Committee proposed to focus on building the central city and town group ring of Dongshan Island,the Dongshan County as a comprehensive The social and economic development of Dongshan County will usher in unprecedented development opportunities.As a super large economy,the main industry is directly related to the sustainable development of the island county(District).The different types of the leading industries often determine the development of the county space.However,the independent geographical location,the extremely fragile ecological environment and the relatively scarce resources of the island county have put forward strict restrictions on the choice of the leading industries,and the path of the county space development is more clear.On the other hand,as a unique geographical block and a distinct historical and cultural accumulation in the inland,the island county(District)determines its spatial pattern with distinctive regional characteristics.In the future construction of the city,it should inherit the historical context and highlight the cultural background so as to avoid the city problem of the one side of the city.Based on the above research background,this paper first reviews the relevant theories of urban spatial structure at home and abroad and urban spatial organization in coastal areas.Secondly,it analyzes the development status of the county town in Dongshan County,summarizes the historical evolution law of its spatial development,and analyzes its evolution characteristics.At the same time,it draws the conclusion that the spatial development of the town is always limited to the inland hinterland,and is in the early stage of "T" type structure,and the main influencing factors of the development of the town space in Dongshan County are macro policy guidance.The space demand to the development of the leading industry.Through the analysis and comparison of the industrial development of Dongshan County and other island counties(District)and the ring Dongshan Economic Zone,the paper deeply analyzes the bottleneck of the industrial development in Dongshan County.Thirdly,the objective conditions of the spatial development of Dongshan County are analyzed from the changes of the external regional environment and internal conditions,and the choice of its future leading industry and development direction is considered,and the industrial development strategy of tourism is emphatically developed.Fourth,the research and analysis of Dongshan County space development model,analysis of the advantages and disadvantages of different development models,in order to solve the main contradictions in the current development,and put forward a more perfect development model.Finally,based on the above analysis,we put forward the functional orientation of Dongshan County in the ring east mountain area and the Zhangnan area,and combine the objective reality of the county resource endowment and resource distribution,choose the leading industry of the county city,determine the location of the county city function,and summarize the type and evolution stage of the spatial structure of the 12 island counties(regions),and choose the future Dongshan County County The urban spatial structure type is the "T" type structure;at the county level,it puts forward the idea of "one city and two wings" and the overall tourism spatial pattern of "one core and three belts";through excavating the historical and cultural genes,combing the natural landscape pattern and constructing the landscape culture spatial pattern under the view of sustainable development;in the county level The "big town town" county population adjustment strategy,"back to the mountain sea" in the south direction of space development,and eventually form the " two core and two axes" of the county space structure.
