摘　　要：乡村聚落的变化表现在数量、规模和空间分布三个方面,且是一个相互关联的统一过程。基于动态模型的设计和G IS方法,对陇中黄土丘陵区秦安县1838～2004年乡村聚落的时空演变过程进行了模拟分析。结果表明,近170年来,秦安县域的村落经历了数量增长,规模扩张、等级增多和空间分布上由疏到密的演变过程。科学规划村镇、优化乡村聚落空间结构不仅是节约土地资源和保护生态环境的需要,也是建设社会主义新农村和促进城乡一体化发展的必然选择。Variability of rural settlements is an united process that shows in quantity, scale and spatial distribution associated each other. Based on design of dynamic model and GIS method, this paper analyses the spatio-temporal variability of rural settlements in Qinan county of loess hilly area during 1838 to 2004. Results indicate that the village quantity increased sharply, the scale of rural settlements enlarged continuously and the spatial distribution of them was from sparse to dense in Qin＇an county in the recent more than 160 years, planning villages and towns scientifically, optimizing spatial structure of rural settlements are not only the demand of land saving and ecological protection, but also the necessity choose of socialism new rural construction and improve urban and rural integrative.
