- Abstract:
- Based on the physical geographic and social economic situation, field survey and literatures, followed the principles of the PSR (pressure-state-response) model, the natural (physical geographic situation) and non natural (including location, economic, social and political factors) factors determining rural settlements distribution was analyed and the rule of its distribution and evolution was explained. The results are shown as follows: (1) in spatial distribution pattern, the rural settlements in Chongqing three gorges reservoir area are characterized by evident spatial variability, which can be divided into seven types, such as high-accessibility & dense-clump pattern of shallow hilly and flatland region in paralleled ridge-valley, normal-accessibility & loose-clump pattern in Karst low mountain and middle mountain trough valley area, normal-accessibility & loose-aggregate pattern in paralleled ridge-valley hilly and low mountain area, high-accessibility & loose-clump pattern in low and middle mountain ridge and basin area, normal-accessibility & loose-aggregate pattern in low and middle mountain area, blocked loose-isolation pattern in low and middle mountain ridge area, blocked loose-isolation pattern in low and middle mountain slope area; (2) the evolution of rural settlements is characterized by simultaneous occurrences of agglomeration and diffusion pattern, such as clustered and net pattern, conglomerate and belt pattern, isolation and beads pattern; (3) the natural factors (physical geographic situation) significantly affect the spatial distribution pattern and evolution of rural settlements in Chongqing Three Gorges Reservoir although the non natural factors are important driving force.
