耦合视角下广西北部湾经济区"三生"功能协调度的时空演变与影响因素
Spatial-temporal evolution and influencing factors of the coordination degree of"production-living-ecological"functions in Guangxi Beibu Gulf Economic Zone from the coupling perspective
摘要
Abstract
In order to reveal the coupling coordination relationship of"production-living-ecological"functions and the spatial-temporal difference of its influencing factors in Guangxi Beibu Gulf Economic Zone,the study constructs the evaluation index system of the national space of"production-living-ecological"functions from 2010 to 2020,and analyzes the function relationship by using the coupling coordination degree model.The spatial-temporal heterogeneity of the factors influencing the functional coordination of"production-living-ecological"is then discussed by using the geographically and temporally weighted regression model.The results show that:1)The production and living functions of counties in the Beibu Gulf Economic Zone are gradually improved,and the spatial pattern of production and living functions is"high in the middle,east and south,low in the north and west".The ecological function is slightly decreased,and the spatial pattern is opposite to the production and living functions.The high-value areas of production and living functions in Nanning city have diffusion effect,and the high-value areas of production and living functions in Yulin and coastal city are at the polarization stage.2)The improvement of production and living functions promotes the coupling coordination degree of"production-living-ecological"functions to improve,from basic coordination to moderate coordination,and the functional conflict of"production-living-ecological"is gradually reduced.The basic coordination of the"production-living-ecological"functions in each district and county is the dominant type,the moderate coordination is the diffusion stage,and the high coordination is the initial polarization.3)Terrain is the basis for the formation of the spatial pattern of the coupling coordination relationship between"production-living-ecological"functions,and per capita GDP is the key factor.Population urbanization,land urbanization,duality of industrial structure,total investment in fixed assets,agricultural labor,total power of agricultural machinery,cultivated land protection intensity and ecological protection intensity have effects on the coupling coordination degree of"production-living-ecological"functions,which are not only related to the stage of regional social and economic development,but also have regional differences.In Guangxi Beibu Gulf Economic Zone,the coupling coordination relationship of"production-living-ecological"functions and its influencing factors are spatial-temporal,and the improvement of production and living functions is the key to functional coordination.The research results can provide reference for the efficient and sustainable utilization of territorial space aiming at the coordinated development of"production-living-ecological"functions.关键词
