摘　　要：以徐州地区SPOT与TM融合遥感影像为主要数据源,选用了自然、环境和社会人文3个方面的10个影响因子,借助ArcGIS软件的空间分析技术,采用取最小值法对乡村聚落空间分布的适宜性进行评价。在研究区的乡村聚落总面积中,高度适宜、中度适宜、低度适宜、临界适宜和不适宜的乡村聚落面积分别占10.94%,42.35%,21.52%,18.13%,7.06%,表明徐州地区的乡村聚落适宜性总体上较高。乡村聚落空间适宜性与其密度分布之间呈现出较强的正相关。最后,结合实际情况对不同适宜性的乡村聚落提出了相应的优化调控措施。Based on Xuzhou fused images of SPOT and TM as the major data sources, spatial information such as rural settlement patches, water system, terrain, et al , is picked up by interpreting the fused images. Using mini- mum of the factor-overlay method, spatial suitability of rural settlements and its distribution are thoroughly analyzed by selecting regionally representative factors according to environmental background in Xuzhou. The results indicate that： 10.94% of the rural settlements area is high suitability, 42.35% of the rural settlements area is middle suita- bility, 21.52% of the rural settlements area is low suitability, 18.13% of the rural settlements area is critical suit- ability, 7.06% of the rural settlements area is non-suitability, which shows that suitability of the rural settlements in Xuzhou is generally high. There is a strong positive correlation between the rural settlement spatial suitability and its density distribution. The concrete approaches and countermeasures with respect to rural settlements rearrange- ment in every suitability rank were put forward.
