Analysis on the Suitability Coupling Coordination Degree of Production-Living-Ecology Space in Changsha-Zhuzhou-Xiangtan
摘要
Abstract
[Objective]The aims of this study are to explore the coupling and coordinated relationship between the suitability of production-living-ecological space,to clarify the main contradictions and influencing factors of the development of territorial space,and to provide scientific basis for promoting the coordinated development of production-living-ecological space in Changsha-Zhuzhou-Xiangtan area.[Methods]Based on the development status of Changsha-Xiangtan area,the evaluation index system of spatial suitability of production-living-ecologyl space was constructed to evaluate the suitability of production,living and ecology space,respectively.The coupling coordination degree model was used to analyze the spatial distribution based on the three types of suitability to explore the relationship between the spatial suitability.[Results]The area of production space was first reduced and then increased,the area of living space increased rapidly,and the area of ecological space decreased rapidly.From 2000 to 2020,a large number of agricultural production space and forest land ecological space transformed into industrial production space and urban living space.The spatial suitability of production-living-ecology space presented the spatial pattern characteristics of of'life-production-ecology'circle layer,which spreaded from Changsha-Zhuzhou-Xiangtan urban area.The suitability of production space was high in north and low in south,high inside and low outside.The suitability of the living space presented the characteristics of'one piece,eight cores and multiple points'.The suitability of ecological space was high in east and low in west,high in south and low in north.In the production-living-ecology space pattern based on suitability,production,living and ecology space accounted for 34.36％,19.55％and 46.09％of the land area,respectively.It was obviously different from the spatial situation of production-living-ecology space,highlighting the key areas of ecological protection.The research area was at a relative coordination level.High coordination,basic coordination,critical imbalance and imbalance areas accounted for 56.29％,36.65％,6.91％and 0.16％of the land area,respectively.The spatial differentiation of the spatial suitability of production-living-ecology space was obvious,reflecting the different development contradictions of territorial space development,so targeted measures should be taken to promote the coordinated development of production-living-ecological space.[Conclusion]The spatial suitability of production-living-ecology space presented the characteristics of the disharmony between ecological space and production or living space,and the relativecoordination between production and living space.The incompatibility between ecological space and production space and between ecological space and living space is the main contradictions in the development of territorial space in Changsha-Zhuzhou-Xiangtan area.Topography is the fundamental factor affecting the coupling and coordination of the spatial suitability of the production-living-ecological space.关键词
