Evolution and Coupling Optimization of Structures and Functions of Rural Regional System in Wuhan Metropolitan Area
The purpose of this study is to construct an index system from the perspectives of"man-land-domain"and"production-living-ecological"spaces,to analyze the spatial-temporal evolution characteristics of structures and functions of rural regional system in Wuhan metropolitan area from 2010 to 2020 and propose the optimization paths based on the coupling relationship between structures and functions.The research methods include index evaluation and elastic coefficient model.The results show that 1)the spatial distribution pattern of structural and functional indexes of rural regional system in Wuhan metropolitan area is relatively stable,and the overall structural and functional indexes show a fluctuating upward trend from 2010 to 2020.2)Wuhan metropolitan area is divided into six types according to the combination characteristics of the changing value of structures and functions with their elastic coefficient.3)The coordinated growth area should identify the main axis of characteristic development and upgrade the structural functional level.Double reduction areas should change passive siphon into active undertaking,relying on local characteristics to lead the industrial development.The structural lag growth areas and structure decrease-function increase reverse areas should build brands based on the location advantages to realize transformation and development.The function lag growth areas and structure increase-function decrease reverse areas should implement modernization of the agriculture and villages to improve the rural living environment.In conclusion,the structures and functions of rural regional system have obvious coupling characteristics of stages and differences.By formulating targeted zoning optimization strategies,the coordinated development of structures and functions of rural regional system can be promoted.
