摘　　要：基于1995-2010年4个时相的遥感影像,通过分析县域尺度的Ripley K函数特征、景观指数变化和行政村尺度的农村居民点空间关联格局特征来研究如皋市农村居民点空间演化特征,并分析演化的驱动过程。结果表明:11995-2010年如皋市农村居民点连通度、聚合度和形状复杂度增加,却未形成有效集聚,呈均匀分布特征,但均匀程度增加不显著。其中2000-2005年,农村居民点空间格局演化特征最显著。2农村居民点局部自相关性强,热点区域由经济较为领先的西北片区逐渐转移到后发追赶的东南片区,在热点转移过程中处于高值簇的乡镇单元会影响附近的区域,热点比重整体上升。3区域工业化和城镇化进程的推进及其空间不均衡性,是驱使如皋市农村居民点空间格局时空演化的主要过程,农村居民收入水平及其完成市民化转变的成本是其主要影响因素。Based on four phases of raster data from 1995 to 2010, this paper studies the spatial evolution of rural residential area and its driving process in Rugao City by analyzing Ripley K function and the change of landscape index of county scale and spatial connection characteristics of village units in rural residential area. The results are： （1）Connectivity of rural residential area, degree of polymerization, and the complexity of shape increased from 1995 to 2010, but rural residential area failed to concentrate on one point and distribute evenly in space. Its uniform did not increase significantly. From 2000 to 2005, the evolution of spatial landscape pattern in the rural residential area was driven by tissue expansion. （2） Local autocorrelation of rural residential area is strong, hotspots gradually shifting from northwest area with better economy to the undeveloped southeast area. Township units in high value cluster will affect their vicinities in the hotspots transfer process. The proportion of high value areas increased as a whole. （3） Promotion of regional industrialization and urbanization as well as the spacial imbalance of Rugao City were the main driving process of spatial pattern evolution of rural residential area, with the income level of rural residents and the cost of completing the public transition as the main factors.
