【摘要】：城乡结合部是城乡争夺土地资源的核心区域,深入开展郊区农村居民点布局优化研究对于统筹城乡发展具有现实意义。本研究以重庆市渝北区古路镇为例,运用转移矩阵法剖析低山丘陵地区城乡结合部土地利用变化特征,从地形条件、生态环境、居民点规模、区位条件4个方面建立评价指标体系对古路镇农村居民点布局适宜性进行评价,结合规划政策导向归纳出5种农村居民点布局优化类型,并根据居民点空间扩展限制分区,制定差异化布局优化策略。主要结论为:(1)2009—2013年5年间古路镇城镇建设用地处于高速扩展之中,导致耕地面积缩减明显,表现出人类活动在城乡发展过程的不均衡性。(2)古路镇农村居民点布局适宜性与居民点平均规模呈现正相关关系;在空间分布上,适宜性等级沿主要交通线两侧逐渐降低。(3)基于规划政策导向、农村居民点空间扩展限制分区,制定差异化的优化策略,城镇转化型居民点逐步转变为城镇建设用地;村庄重点扩展类型居民点建设成为中心社区,承担对周围村落的服务职责;村庄挖潜型居民点集约利用土地,积极发展休闲农业产业;村庄合并型居民点整合零散用地,共享公共服务资源;迁移型居民点迁出新建,优化农村"三生"空间,以实现低山丘陵地区城乡结合部农村居民点的城镇化和集约化。
[Abstract]:Urban and rural areas are the core regions of urban and rural competition for land resources. It is of practical significance to carry out in-depth research on the layout optimization of rural residential areas in suburban areas. This study takes Gulu Town, Yubei District, Chongqing as an example. Using the transfer matrix method to analyze the characteristics of the land use change in the urban and rural areas in the low mountain and hilly areas, from the terrain conditions, the ecological environment, the residential area scale, The evaluation index system was established in four aspects of location conditions to evaluate the suitability of rural residential land distribution in Gulu Town, and five types of rural residential land layout optimization types were concluded in combination with planning policy guidance, and the zoning was restricted according to the expansion of residential space. The main conclusion is that the land used for urban construction in Gulu Town is expanding at a high speed during the five years from 2009-2013 to 2013, resulting in the reduction of cultivated land area. It shows that the unbalance of human activities in the process of urban and rural development. (2) the suitability of rural residential areas in Gulu Town is positively related to the average scale of residential areas, and the spatial distribution, On the basis of planning policy orientation, rural residential space expansion and restriction zoning, the optimization strategy of differentiation is formulated, and the urban transformed residential areas are gradually transformed into urban construction land. The suitability grade is gradually reduced along the two sides of the main traffic lines. The construction of the village key expansion type residential area becomes the central community, undertakes the service responsibility to the surrounding village; the village excavates the latent type residential area intensively uses the land, develops the leisure agriculture industry actively; the village merges the settlement place to integrate the scattered land, Share the public service resources, move out of the new residential areas, optimize the rural "Sansheng" space, so as to realize the urbanization and intensification of the rural residential areas in the combination of urban and rural areas in the low mountain and hilly areas.
