苏南地区乡村聚落空间格局及其驱动机制

Spatial Pattern and Its Driving Mechanism of Rural Settlements in Southern Jiangsu

基于苏南地区土地变更调查数据,通过空间分析方法,对苏南地区乡村聚落空间格局特征进行深入分析,并从市域和县域两个层面探讨了乡村聚落空间格局形成的驱动力,初步构建了驱动力机制。结果表明:苏南地区乡村聚落分布整体较为集聚,苏锡常地区村庄密度较高,宁镇地区呈稀疏化分布,村庄整体分布与地貌类型具有较高的相关性。规模面积整体呈现出明显的区域差异,各县域单元乡村聚落用地总体较低。在此基础上提炼总结了乡村聚落空间格局形成的影响因子,包括政府调控、城镇化、工业化和交通发展等,并基于社会发展角度构建了驱动力机制。

Based on the land change survey data of Southern Jiangsu in 2010, by using the related spatial analy- sis method, the rural settlement spatial pattern characteristics of Southern Jiangsu were analyzed, and on the basis of the district and county aspects the rural settlement spatial pattern was discussed, the driving mecha- nism of driving force mechanism was constructed. Some conclusions are drawn as follows： The overall distri- bution of rural settlement is concentrate, Su-Xi-Chang area has a higher density, Ningzhen area is sparse distri- bution, the overall distribution of rural and landform types has higher correlation. The main factors of rural set- tlement spatial pattern were summarized. The dynamic mechanism of rural settlement spatial pattern in south- ern Jiangsu is the formation of many factors. Country renewal development and external factors lead to recon- struction of rural settlement space. In the different stage of transformation development, action condition and function efficiency that influence the rural settlement spatial pattern are different. The quantitative analysis to rural settlement space reconstruction driving force in the regional level and county level indicates that the driv- ing force of influencing rural settlement space reconstruction is mainly economic conditions, urbanization, and industrialization and transportation development. On that basis, the article has constructed dynamic mechanism of the rural settlement space reconstruction, and cleared the dominant force in various stages, as well as the ru- ral settlement spatial morphological characteristics. At last, the main power and the rural settlement spatial mechanism were analyzed.
