摘　　要：探讨吉林省的城乡居民地的空间格局对于城镇建设和相关基础设施建设无疑具有很大的参考价值。本文以TM为数据源提取了吉林省居民地空间分布信息。在GIS技术支撑下,结合区划理论和聚落地理学说,分析了吉林省城乡居民地的空间格局。结果表明,吉林省城乡居民地空间分布区划为三个区,分别是东部区、中部区和西部区。中部区城镇居民地和农村居民地密集,且城镇化程度最高;东、西部区城镇居民地景观指数无明显差别,但农村居民地的景观指数明显有差别。从居民地分布类型来看,城镇居民地与农村居民地在各区内都呈随机分布,但其指示参数最近邻点指数还是体现出明显的区划差异。The study on spatial pattern of urban and rural residential landuse in Jilin is important for the construction of the cities and towns. The study source data is TM image in 2000. Supported by GIS, together with the theory of regionalization and settlement geography, the spatial pattern of urban and rural residential landuse in Jilin was analyzed. The result shows that the regionalization of urban and rural residential landuse in Jilin is composed by three subrgions. The central subregion is one part of Jilin that has the highest intensity of urban and rural residents. The landscape indices of urban residential area between east subregion and west subregion have no marked difference. But the landscape indices of rural residential area between east subregion and west subregion have marked difference. According to the theory of settlement geography, the distribution type of urban residential land and rural residential land in all subregions is stochastic type, but the reference index, the nearest index is still different in all subrgions.
