摘要: 探究国土空间生产-生活-生态功能(即"三生"功能)的耦合协同关系和时空演化特征是优化乡村地域功能、推进乡村振兴的关键举措。在明确"三生"功能逻辑内涵的基础上,以县域为评价单元,利用耦合协调度模型、局部自相关分析、Dagum基尼系数及子群分布方法,测算2002、2007、2012和2017年江苏省生产功能、生活功能、生态功能以及"三生"功能综合评价值,揭示"三生"功能多维尺度的时空演变和耦合协调规律。结果表明,研究期内江苏省乡村"三生"功能高值集聚特征凸显,生产功能时空异质性明显,苏北地区及其与苏中地区交界处生产功能优势突出,生态功能优势地域单元呈现扩张趋势。江苏省乡村"三生"功能多处于磨合阶段和高水平耦合阶段,极弱耦合地域单元占比最低。苏北地区中等耦合地域组团集聚,苏中、苏南地区主要为高水平耦合单元。"三生"功能一般协调地域单元占比最高,耦合协调发展水平整体呈减弱态势。江苏省乡村地域生产-生活-生态功能两两之间低水平耦合协调发展情况持续恶化,多处于失衡协调区和过渡协调区,并未实现空间良性共振。江苏省乡村"三生"功能非均衡性经历上升-降低-上升的演化过程,苏南地区组间差距始终较小。生活功能非均衡程度波动起伏趋势与"三生"综合功能和生产功能相一致,研究期内生态功能的地域非均衡性逐渐减弱。卫生医疗水平和生态环境情况对于提升江苏省乡村"三生"功能具有关键作用。

Abstract: Exploring the coupling coordination and spatio-temporal evolution characteristics of "production-living-ecological" functions is of great significance. It is a key measure to optimize the regional function and promote revitalization of rural areas. The coupling coordination model, local auto-correlation analysis, Dagum Gini coefficient and subgroup distribution method were employed in this study. Based on clarifying the connotation of "production-living-ecological" functions, and taking "county" as the evaluation unit, the evaluation value of the production function, living function and ecological function as well the comprehensive function of Jiangsu Province in 2002, 2007, 2012 and 2017 were calculated. Furthermore, the spatial-temporal evolution and coupling coordination law of "production-living-ecological" functions with multi-dimensional scale were revealed. It shows that during the study period, the high value agglomeration of rural "production-living-ecological" functions in Jiangsu province was prominent, and the spatial and temporal heterogeneity of production function was obvious. Northern Jiangsu and its border area with Central Jiangsu Province had prominent advantages in production functions, and the regional units of ecological function superiority showed an expanding trend. The "production-living-ecological" functions in rural areas of Jiangsu Province are mostly in the running-in stage and the high-level coupling stage, and the proportion of extremely weakly coupled regional units was the lowest. The middle and southern regions of Jiangsu Province were mainly high coupling units. The proportion of general coordinated regional units of "production-living-ecological" was the highest, and the level of coupling coordinated development showed a weakening trend. Moreover, the low level coupling and coordinated development of production-living-ecological functions in rural areas in Jiangsu Province had been deteriorating continuously, and most of them were in the unbalanced coordination zone and the transition coordination zone, without realizing the benign spatial resonance. The imbalance of rural "production-living-ecological" functions in Jiangsu Province experienced an evolutionary process of rising, decreasing and rising, and the gap between groups in southern Jiangsu Province was always small. The fluctuation trend of disequilibrium degree of life function was consistent with the comprehensive function of "production-living-ecological" and the regional disequilibrium of ecological function gradually weakened during the study period. The level of health care and ecological environment play vital roles in promoting the "production-living-ecological" function in rural areas of Jiangsu Province.
