安徽省县域乡村“三生”功能及耦合协调时空格局分析

THE SPATIO-TEMPORAL PATTERN OF RURAL“PRODUCTION-LIVING-ECOLOGICAL”FUNCTION AND COUPLING COORDINATION AT COUNTY LEVEL OF ANHUI PROVINCE

[目的]通过探索乡村地域生产、生活、生态“三生”功能的交互关系和演化规律,为安徽省乡村空间功能优化、乡村发展活力提升、乡村生态环境改善建设提供参考。[方法]文章基于乡村“三生”功能测度指标体系和耦合协调度模型,测算1997—2017年安徽省县域乡村“三生”功能的发展水平和耦合协调度,并利用空间自相关分析揭示了乡村“三生”功能耦合协调的时空格局演化特征。[结果](1)研究期间,安徽省乡村“三生”功能发展水平空间差异缩小,乡村发展水平趋向均衡,其中生活功能对乡村发展起到主导作用。(2)安徽省乡村“三生”功能耦合度整体较高,以高耦合和良性共振耦合为主,空间上呈现西高东低的特征。(3)安徽省乡村“三生”功能耦合协调水平主要表现为基本协调,呈北低南高和片状分布的特征,区域间差异逐渐缩小,且空间正相关关系增强,低值聚集区由皖中向皖北地区转移。[结论]目前安徽省乡村“三生”功能整体水平较低,耦合协调度有待提高,未来需进一步提高乡村“三生”功能以支撑乡村转型和振兴发展。

By exploring the interactive relationship and evolution law of rural“production-living-ecological”function,this research aims to provide references for optimizing the rural spatial function,enhancing the rural development vitality and improving the rural ecological environment in Anhui province.Based on the measurement index system of rural“production-living-ecological”function and the coupling coordination model,the development degree and coupling coordination degree of rural“production-living-ecological”function at county level of Anhui province from 1997 to 2017 were measured,and the spatio-temporal pattern of coupling coordination degree of rural“production-living-ecological”function was further analyzed by spatial autocorrelation analysis.The results were listed as follows.(1)The spatial disparity of the development level of rural“production-livingecological”function in Anhui province had narrowed during the period of 1997—2017,and the rural development level tended to be balanced,in which the living function played a leading role.(2)The overall degree of coupling degree of rural“production-living-ecological”function in Anhui province was relatively high,with high coupling and benign resonance coupling as the main features in most counties,and the spatial pattern revealed the characteristics of high in the west and low in the east.(3)The level of coupling coordination degree of rural“production-living-ecological”function in Anhui province was mainly characterized by basic coordination,which was low in the north and high in the south and flaky distributed.The regional disparity had narrowed and the positive spatial autocorrelation had enhanced with the low value cluster areas transferring from central Anhui to northern Anhui.In summary,the overall level of rural“production-living-ecological”function in Anhui province is not high,and the degree of coupling coordination needs to be improved.In the future,the function of rural“production-living-ecological”function needs to be further improved to support rural transformation development and rural revitalization.
