[目的]以多功能评价为基础开展农村居民点布局优化,能够有效满足农村居民点的精细化、差异化治理需求。[方法]以西南丘陵区典型代表性的重庆市荣昌区为例,利用分层抽样选择12个样点村域,结合内部用地形态和外部环境适宜性构建指标体系,评价不同类型农村居民点生产功能、生活功能和生态功能的优势度差异,划定农村居民点功能优化分区并制定相应优化策略。[结果]农村居民点内部结构及承载功能表现出显著地域分异规律,其农业生产功能随着与城镇距离缩短而显著衰弱; 非农生产功能和生活功能优势度的分布特征均表现为由城镇中心向较远区域递减趋势; 生态功能优势度表现为远郊型>中心型>近郊型。荣昌区农村居民点的分区优化策略可划分为I类产业重构式、Ⅱ类社区营造式、Ⅲ类生态涵养式和Ⅳ类移民搬迁式4种。[结论]综合内部用地特征和外部环境适宜性对农村居民点“三生”功能优势度进行评价,可为西南丘陵区农村居民点布局优化提供新的思路。 |

Abstract: |
The layout optimization of rural settlements based on multifunction evaluation can effectively meet the demands of refined and differentiated governance. In order to analyze the characteristics of rural settlements in southwest hilly area, the data were collected from 12 sample villages by stratified sampling in Rongchang district of Chongqing. On the basis of the internal land use classification and factors of external environmental suitability of rural settlements, this research evaluated the dominance difference of production living ecology function between different types of rural settlements, and delineated the function optimizing zone of rural settlements with targeted optimizing strategies formulated in accordance with the results of function difference. The results showed that spatial differentiation characteristics of internal structure and carrying capacity took on distinct differences between rural settlements. The agricultural production function was significantly weakened along with the shortening of the distance from towns. The distribution characteristics of the non agricultural production function and living function kept consistent, showing a decreasing trend from the urban center to the far area. The dominance of ecological function of rural settlements appeared as outer suburban type>central type>suburban type. According to the findings, the optimizing strategies of rural settlements in study area were divided into 4 modes, including rural industrial restructuring mode, rural community empowerment mode, ecological conservation mode and immigrant relocation mode. This research attempts to evaluate the difference of rural settlements′ dominant function, by integrating the characteristics of the internal land use and the external environment suitability into consideration, which could provide a new idea for optimization and renovation of rural settlements in hilly areas. |
