Consolidation partition and mode design of rural construction land based on residential field and power theory

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.
