陇中黄土丘陵区乡村聚落发展及其空间扩展特征研究——以甘肃省秦安县为例

Research on Rural Settlement Development and Spatial Expansion Characters in Loess Hilly Area——Taking Qin'an County of Gansu Province for Example

乡村聚落是乡村人口居住和生产生活的场所,是乡村地域空间的人口聚居点,其形成和发展受自然条件和乡村社会、经济、文化等因素的深刻影响。本文基于历史文献资料和统计数据,对历史时期和新中国成立后秦安县域乡村聚落的数量增长与发展演变进行了分析研究,并对乡村聚落的分裂演变进行了理论假设与分析;运用GIS方法,对乡村聚落的区位演变和空间扩展过程进行了分析研究,在此基础上总结分析了黄土丘陵区乡村聚落发展及空间扩展的基本特征与规律。

Rural settlement is the place of habitation, production and the living for rural people, which is the settlements of rural regional horizon and whose formation and development evolution were effected profoundly by nature condition, rural society, economy and culture. According to historical literature and statistical data, scalar increase and evolution of rural settlement of Qin ＇an County during the two periods of the historical and after New China Founded were analyzed. Besides, the theory supposition and the analysis were carried on to the village set- tlement fission evolution. Using the method of GIS, the evolution of settlement location and the rural settlement spatial expansion process were discussed. Based on these, the basic characters and rules of rural settlement development and spatial expansion characteristics in Loess Hilly Area were summarized.
