摘　　要：根据2006年Landsat TM影像,利用Erdas和ArcGIS软件,结合区划理论和聚落地理学,对辽宁省中部城市群的居民地分布格局进行了研究。结果表明:1)辽宁省中部城市群居民地在斑块数量上主要以小型斑块为主,斑块面积<1km2的斑块数量达斑块总数的96.38%,在斑块面积上以沈阳等几个大型城市的居民地占主要地位。2)依据居民地面积的空间比重将辽宁省中部城市群居民地划分为东部地区、沈阳地区和西部地区3个特征区域,其中沈阳地区平均斑块面积最大,城市化程度最高;西部地区斑块密度最大,居民地最为密集;东部地区平均斑块面积和斑块密度均最小,居民地发育程度低于另2个区域。3)尽管居民地在3个区域内都呈随机分布,但其指示参数——最邻近点指数还是体现出明显的区划差异。4)居民地分布受中心城市的影响显著,各中心城市的辐射范围不同,大小依次为沈阳>鞍山>铁岭>营口>辽阳>本溪>抚顺。Based on the Landsat TM image in 2006 and by using Erdas and ArcGIS software, in combining with the theories of regionalization and settlement geography, the spatial patterns of the habitation areas in the conurbations of central Liaoning Province were studied. In the test habitation areas, small patches occupied a large proportion, with the patches smaller than 1 km^2 accounted for 96.38% of all patches. Shenyang and some other conurbations took up the main position in the habitation areas. The habitation areas could be regionalized into east region, Shenyang region, and west region. Shenyang region had the largest average patch area and the highest urbanization; west region had the highest patch density and the densest habitation area; while east region had the smallest average patch area and the lowest patch density, with the development of habitation area being slower than the other two regions. The habitation areas in the three regions were in stochastic distribution, but the reference index （the nearest index） differed ohviously among the regions. Centric cities had great effects on the distribution of habitation areas, with the radiation range in the sequence of Shenyang 〉 Anshan 〉 Tieling 〉 Yingkou 〉 Liaoyang 〉 Benxi 〉 Fushun.
