Population is the most active factor affecting city development. To understand the distribution characteristics of urban population is of significance for making city policy decisions and for optimizing the layout of various urban infrastructures. In this paper, the information of the residential buildings in Shenyang urban area was extracted from the QuickBird remote sensing images, and the spatial distribution characteristics of the population within the Third-Ring Road of the City were analyzed, according to the social and economic statistics data. In 2010, the population density in different types of residential buildings within the Third-Ring Road of the City decreased in the order of high-storey block, mixed block, mixed garden, old multi-storey building, high-storey garden, multi-storey block, multi-storey garden, villa block, shanty, and villa garden. The vacancy rate of the buildings within the Third-Ring Road was more than 30%, meaning that the real estate market was seriously overstocked. Among the five Districts of Shenyang City, Shenhe District had the highest potential population density, while Tiexi District and Dadong District had a lower one. The gravity center of the City and its five Districts was also analyzed, which could provide basic information for locating commercial facilities and planning city infrastructure.
人口是影响城市发展最活跃的因素。了解城市人口分布特征对于制定城市政策决策以及优化各类城市基础设施布局具有重要意义。本文从快鸟遥感影像中提取了沈阳城区住宅建筑信息，并依据社会经济统计数据，分析了城市三环内人口的空间分布特征。2010年，城市三环内不同类型住宅建筑的人口密度由高到低依次为高层街区、混合街区、混合花园、旧多层建筑、高层花园、多层街区、多层花园、别墅街区、棚户区、别墅花园。三环内建筑物空置率超过30%，这意味着房地产市场严重积压。在沈阳市的五个区中，沈河区潜在人口密度最高，而铁西区和大东区较低。还分析了城市及其五个区的重心，可为商业设施选址和城市基础设施规划提供基础信息。
