乡镇规划调控下的农村居民点空间布局优化.

The spatial layout optimization of rural settlements is the main content of new rural construction, and also one of the key contents of the overall land use planning. The rational spatial layout optimization of rural settlements can not only promote the intensive use of land resources and improve rural production and living environment, but also accelerate the transfer of rural labor force and further narrow the gap between urban and rural development. In order to determine the type of spatial layout optimization of rural settlements scientifically and guide the optimization of spatial distribution of rural settlements and the practice of new rural construction effectively, this paper put forward a spatial distribution optimization method of rural residential areas based on town planning regulation, which was applied to Kekeyiligeng Town in Wuchuan County, Inner Mongolia Autonomous Region. Under the regulation of land use planning at town level, the following steps were in process: First of all, the rural residential areas were divided into 2 different evolution directions based on the location within or outside the boundaries of urban construction land expansion: urbanization and non-urbanization. Specifically, the rural residential areas located within the boundaries of urban construction land extension were identified as urbanization type; conversely the rural residential areas outside the extended boundary range were defined as non-urbanization type. Secondly, the spatial layout optimization type of the urbanization type residential areas was determined as the community-based management mode due to that the rural residential areas as urbanization type were likely to be included in urban construction in their future development. Thirdly, for non-urbanization rural settlements, the evaluation index system for the comprehensive influence of rural residential patches was constructed from 3 aspects: the coordination of town planning, the convenience of production and living, and the activeness of residential areas. Based on comprehensive evaluation scores, the spatial layout optimization types of non-urbanization type were accordingly divided into 3 categories: comprehensive development, in-situ renovation, and combined migration. Finally, the rural settlements optimal layout scheme with 4 optimization types was formulated. The results showed that there were 6 rural residential areas identified as community-based management areas in the study area, with an area of 15.29 hm2, accounting for 2.92% of the total area of the town; 46 comprehensive development areas, with an area of 178.28 hm2, accounting for 35.04% of the non-urbanized rual residential area; 53 in-situ renovation areas, with an area of 189.20 hm2, accounting for 37.20%; 40 combined migration areas, with an area of 141.22 hm2, accounting for 27.76%; the paper also put forward a more specific optimization plan for the 4 optimization types of rural residential spatial layout. Under the framework of town planning regulation, and given full consideration to the space-time arrangement of the rural settlements layout optimization in the town planning period, the optimal layout scheme obtained by the method constructed in this paper is more accordant with practical circumstances in China, and the spatial distribution optimization method of rural residential areas based on town planning regulation can provide a new idea for spatial optimization and renovation of rural residential areas and also provide reference for related research.
