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 three-year 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.
