Abstract:

Under the background of land space planning reform, the land space of county is divided into three types: Urban space, agricultural space and ecological space. Among them, the planning of rural residential area system is the key to the agricultural space reconstruction. The implementation of Rural Revitalization Strategy requires the construction of rural community system according to the law of rural population migration. The characteristics of rural settlement spatial pattern and the optimized reconstruction mode are the foundation of rural community reconstruction. Based on the land GIS data and the statistical data of villages and towns, the cluster analysis and fractal method are used to explore the form types and spatial system characteristics of rural settlements in the Jianghan Plain. The research shows that the Jianghan Plain has formed ‘two category and four types’ of rural settlement space forms due to the difference of its internal natural environment matrix: One is the balanced mosaic settlement form in the low-hilly and mound areas, which can be divided into two subtypes: high-density & low-hilly point form and medium-density & mound crumb form, this rural settlement present a ‘star point’ spatial structure. Another is shaft-dependent settlement form in the river and ditch network areas, which can be divided into two subtypes: low-density & lake-arc form and medium-low density & river-ditch linear form, this rural settlement presents a ‘point-axis’ spatial structure. The characteristics of ‘two category and four types’ rural settlement form and spatial system in the Jianghan Plain are typical in the middle reaches of the Yangtze River Plain. It can provide theoretical basis and practical guidance for the spatial reconstruction of such rural settlements and the optimization of rural residential area system.
