【摘要】 乡村人居环境是一复杂巨系统,其可持续发展力是各子系统间物质、信息与能量相互流通与交换的结果,本文从经济发展、生产生活、生态环境3个子系统入手构建乡村人居环境可持续发展力的评价指标体系,以1997—2015年重庆市37个区县的面板数据为数据源,运用发展水平(衡量乡村人居环境可持续发展态势)、发展效率(反映乡村人居环境发展趋向可持续的快慢程度)和协调指数(反映各子系统发展水平均衡程度)构建乡村人居环境可持续发展力测度模型,分析了乡村人居环境可持续力并探究其时空分异特征,为因地制宜践行《农村人居环境整治三年行动方案》提供策略支持。结果表明:1997—2015年,乡村人居环境可持续发展力时序上总体态势向好,其中发展水平逐步上升,发展效率波动剧烈,协调性稳步提高,各子系统间可持续发展力差异性较大;乡村人居环境可持续发展力在空间上总体呈现西高东低、"中心-边缘"的分异格局,区县间差异性明显,其中经济发展子系统呈"多级核心-外围"辐射圈层式差异化增长格局、生产生活子系统呈自西向东扩散式增长格局,生态环境子系统总体上先降后升,呈波浪式不均衡增长格局;从政府"制导引导"、城乡"双轮"联动、"点-极-核"整治模式等方面提出了相关整治策略。更多还原

【Abstract】 As a complex system, the sustainable development ability of rural human settlements is the result of the exchange of materials, information, and energy among its subsystems. This study established an evaluation index system of sustainable development ability of rural human settlements based on the three subsystems of economic development, living-production, and ecological environment, and used panel data from 37 districts and counties in Chongqing Municipality from 1997 to 2015 as the data sources. By using development level that measures the sustainable development situation of rural human settlements, development efficiency that reflects the pace of sustainable development, and coordination index that reflects the coordination degree among subsystems, this study analyzed the sustainable development ability of the rural human settlements and examined its spatiotemporal differentiation characteristics, in order to provide some strategies for the practice of the threeyear action plan of rural human settlements improvement in Chongqing Municipality. The results show that,from 1997 to 2015, the overall sustainable development ability of rural human settlements of Chongqing was reasonably high. Among the three subsystems, development level gradually improved, development efficiency fluctuated significantly, coordination degree enhanced stably, and the development level showed great differences among the subsystems. The sustainable development ability of rural human settlements presents a spatial pattern of "low in the east, high in the west" and center-periphery differentiation, as well as wide variations among the districts and counties as a whole. The development level of the economic development subsystem showed a spatial pattern of multilevel core-surrounding zonal differentiated growth. The development level of the living-production subsystem showed a spatial pattern of diffusion growth from the west to the east.The development level of the ecological environment subsystem declined first and then increased and showed a spatially unevenly growth. On these bases, this study put forward some strategies for improvement from the aspects of planning and guidance by the government, urban and rural coordination, and the"point-pole-core"development model.更多还原
