摘要: 综合运用判断矩阵法、居住场势度量法和三维空间分类法, 依据居住场势理论, 探索一种集理论关联、功能指向、效用分析为一体的新型农村建设用地整治分区和模式设计方法, 以期为新一轮土地整治规划编制提供技术支撑, 为土地整治项目实施提供方法借鉴, 并以重庆市九龙坡区白市驿镇为例进行了农村建设用地整治分区与整治模式研究。研究结果显示, 研究区可划分为4种整治类型区, 其中Ⅰ类区适宜采用生态移民涵养式整治模式, Ⅱ类区采用新型农村产业化整治模式, Ⅲ类区采用新型农村社区化整治模式, Ⅳ类区采用生态压缩发展式整治模式。计算得到的白市驿镇各村居住场势分量呈现地域性特征: 生产分量地域特征最为明显, 由建制镇周围向较远区域递减, 近郊型行政村生产分量值(Nip)高于中心和远郊型行政村; 生活分量值(Nil)分布特征与其基本相同; 生态分量值(Nie)较高区域集中在远郊森林密集、生态环境良好的山区。通过与各行政村自然、社会经济本底情况的验证比对, 白市驿镇整治分区结果符合区域实际特征。因此, 本研究认为区域内居住场势差异是影响农户自主迁徙的客观推动力, 以居住场势理论为指导进行整治分区和模式设计, 可以体现农村建设用地整治的区域特征与功能指向, 为整治活动的科学开展提供参考。Abstract: The consolidation of rural construction lands is an important means of coordinating farmland protection and economic development. It is also an innovative platform for promoting urban-rural integration, rural reconstruction and urbanization. However, the traditional consolidation of rural construction land only emphasizes the consolidation of inefficient, unreasonably used and, unused lands and damaged lands, ignoring the influence of "humans" on land use. Humans easily subject land to utilization which do not adjust measures to local conditions as reflected in the spatiotemporal pertinence. The residential field and power theory includes both subjective and objective factors such as natural, productive and manpower resources. The theory analyzes the appropriateness and scientificity of rural construction land consolidation from multiple dimensions and perspectives, which to some degree, solves the problems of regional characteristics and special function orientations easily ignored in traditional research methods on sub-region consolidation. Thus according to residential field and power theory, this research explored a new method of consolidation partition and mode design of rural construction land, integrating the theory correlation, function pointing and utility analysis through comprehensive application of the methods of judgment matrix, living potential measurement and taxonomy in three dimensional space. This provides technical support for new rounds of consolidation and planning of lands and offers methods and references for implementing land consolidation projects. This paper studied the consolidation partition and model of rural construction lands using Baishiyi Town of Jiulongpo Region in Chongqing City as a case. The research results showed that the study areas could be divided into four kinds of terrains. Area Ⅰ mainly included Qinghe, Zhenwu and Sanduo Villages which adopted the consolidation mode of ecological migration self-restraint. Area Ⅱ mainly included Hailong, Moujia, Taici and Jiuli Villages which adopted the consolidation mode of a new type of rural industrialization. Area Ⅲ mainly included Gaofeng Village which adopted the consolidation mode of new rural community. Then Area Ⅳ included the other villages which adopted the consolidation mode of ecological compression development. Based on the calculations, the residential field and power component of villages in Bailongyi Town showed regional characteristics. Among the characteristics, production component was the most obvious and it decreased progressively from suburb villages around town to outer suburb village. The production component of suburb villages was higher than that in the core and outer suburb villages. The distribution characteristics of living component were similar to those of production component. High ecological component was distributed in mountainous areas with intensive forests and good ecological environment in suburban regions. Through verification and comparison of natural with socioeconomic situations of the administrative villages, the results of consolidation partition in Baishiyi Town practically conformed to the regional characteristics. It was therefore suggested that the difference in residential field and power of different regions was the objective driving force influencing the independent migration of farmers. The consolidation partition and mode design guided by the residential field and power theory, embodied regional characteristics and functional guidance of rural construction land consolidation and provided relevant reference for scientific research on land consolidation.
