| 摘 要： | 探究乡村三生空间功能间的互动关系,是当前乡村空间优化过程中亟待解决的关键问题。结合国土空间规划“三生”空间理论与耦合协调模型,定量测算2005年、2010年、2015年重庆市37个区县的乡村三生空间功能及其两两间的耦合度和耦合协调度并进行空间比较和时序分析。结果表明：耦合度呈现低耦合、拮抗、磨合、协调耦合四种类型,耦合协调度呈现中度失调、基本协调、中度协调三种类型;乡村三生空间功能耦合协调的时空格局差异显著,空间上呈现出“西高东低”的格局特征,时间上呈现由低水平耦合向协调耦合发展的波浪式演进特征;乡村三生空间功能两两之间耦合协调状态差异明显,“生活—生态”功能耦合协调情况较差,是未来优化乡村空间的重点方向。

| Abstract: | The production space function, living space function and ecological space function promote and restrict each other; the complex relationship among the three functions is the major cause of the development and evolution of production-living-ecological space in rural areas. The coordinated and mutual development of the rural production-living-ecological space function is one of the most crucial issues in the current process of spatial restructuring in rural China. In this study, we established an index system for rural production-living-ecological space function with the production-living-ecological space theory in territorial space planning, based on the fact that a coupling coordination model was built. Therefore, after quantitatively calculating the coupling degree and coupling coordinate degree (2005, 2010, and 2015) of 37 districts and counties in Chongqing, we conducted spatial comparison and temporal analysis, the results are shown as follows. There were four types of coupling degree (low level coupling type, moderate level coupling type, break-in coupling type and coordination coupling type) and three types of coupling coordination degree (moderate incongruous type, elementary coordination type and moderate coordination type) appeared in rural production-living-ecological space function, which offered implications for calculating the mutual relationship among the three functions. The coupling coordination degree of rural production-living-ecological space function exhibited significant difference spatially and temporally; to be specific, it presented a spatial pattern of "high in the west and low in the east". In the time dimension, it waved from low level to high level coupling. There were obvious differences of coupling coordination status among every two of the three rural space functions. The coupling coordination of "production-living space function" was higher than that of "production-ecological space function" and "living-ecological space function" in the same period, whilst the coupling coordination of "living-ecological space function" had the poorest condition. Thus, living-ecological space function should be the key point for spatial restructuring and it must be proposed firstly in rural areas. |
