The Research On The Spatial Conflictof Ecological-production-living Spaces Under Urban Renewal In The Old City Of Fuzhou

Urban renewal is the most effective means to liquidize remnant land of the old city,and it is the inevitable choice for the sustainable development of the city.Such as urban expansion,there will be various problems in the process of urban renewal.The problem of spatial conflicts derived from it should be valued and explored by government departments and academia.The current research on land use spatial conflict in academic circles based on the spatial conflict of city expanding,and result in the city renewal research carried out research on the spatial conflict less conducive to the rational use of land to solve the city update,promote the city space layout and sustainable development.In this study,located on the southeast coast of the national historical and cultural city of the old city area of Fuzhou as the research object,the city land use vector data in 2000,2009 and 2015 from the angle of urban renewal based on the perspective of quantitative analysis between Fuzhou urban renewal and transformation of all types of relations;on this basis,to explore the old city of Fuzhou before and after the update time the spatial pattern of evolution using three space theory,and using the theory of landscape ecology,construction index,vulnerability index,space complexity and stability of three adjacent compatibility index of spatial conflict index,quantitative analysis of the old city of Fuzhou three spatial conflict degree.The results show that:(1)In the past 2000-2015 years,the activities of the old city in Fuzhou were mainly characterized by the following characteristics:? the intensity of renewal was larger and the coverage was wide.The old city of Fuzhou has undergone great changes for 2000-2015 years,bid farewell to "paper framed Fuzhou",and in 2015 to update the area close to the study area 40%;?the update object with the "old three" to "two new" trend,mainly for the rural homestead,the old urban residential land and industrial land for storage.The "three old" update for the new urban residential land and commercial use of"two new";?the show along the periphery of a new trend of roads and rivers,scenic spots.(2)During the period of 15a,the renewal mode of the old city of Fuzhou was gradually enriched,but it still took the absolute advantage of dismantling and rebuilding.In the past 200-2015 years,the old city renewal mode in Fuzhou mainly includes 4 modes:demolition and reconstruction mode,cultural protection mode,environmental improvement mode and industrial upgrading mode,accounting for 87.91%,2.94%,3.65%and 2.50%respectively.(3)During 15a,Fuzhou before and after the renovation of the old city,three spatial structure changes significantly,with "two or two down a smooth" characteristics,specific performance is a kind of living space dominates a living space and a rising proportion of production space,but with a kind of living space growth;followed by two class two kinds of living space and production space dropunceasingly,ecological space decreased and then increased,but the overall stable,slightly increased.In 2000,the two types of living space and two types of production space distribution were concentrated,but with urban renewal,the two types of space were almost completely transformed.During 15 a,the spatial transfer performance for Fuzhou urban renewal process,a kind of living space and a production space increased from two main categories and two kinds of production space,living space less,that Fuzhou urban renewal mainly in the transformation of two kinds of production and living space construction of a kind of life and production space.(4)The 2000-2015 year old Fuzhou three spatial degree of conflict in a controlled(stable and controllable+basic controllable)conflict,which reached more than 70%,showed that the old city of Fuzhou three space in proportion,but break the coordination trend,needs to pay more attention to the prevention of spatial conflict;small changes in spatial conflict index,small fluctuations in 2000-2009 years decreased 2009-2015 years after the rise.Although the conflict in Fuzhou urban renewal process severity is small,but there are still serious conflicts of space,the main reason is?the stability of the ecological space to support life and production increasing,it is difficult to live with the rapid development of the production space ecological space matching;?soil patch is broken,the low efficiency of land utilization and economic benefits;?update leads to excessive development.
