摘　　要：基于QuickBird卫星影像,采用阴影长度法对城市居住建筑面积进行测算,结合社会经济统计数据对沈阳城市潜在人口分布特征进行分析.结果表明:2015年,沈阳市三环内各行政区潜在人口分布不均;三环内潜在人口空间分布呈现典型的圈层结构特征;各行政区潜在人口数量为铁西区>沈河区>皇姑区>于洪区>和平区>大东区>东陵区;各行政区潜在人口密度为铁西区>和平区>沈河区>皇姑区>于洪区>大东区>东陵区;城市西部潜在人口密度高于东部,南部高于北部.居住建筑及人口的空间分布与区域的自然条件、经济状况以及基础设施建设等因素紧密相关.在未来城市规划建设中,应考虑加强铁西区以及中心城区的基础设施建设,适当增加公园绿地数量,合理开发城市南部的居住用地,适当控制居住人口数量,避免造成较大的环境压力.The urban residential building area was measured by shadow length method based on information extracted from the QuickBird remote sensing images,and the spatial distribution characteristics of the city population were analyzed according to the social and economic statistics.The distribution of the population in different districts within the Third-Ring Road of Shenyang was uneven in 2015,and the spatial distribution of potential population within the area presented a typical circle structure.The district＇s potential population decreased in sequence of Tiexi,Shenhe,Huanggu,Yuhong,Heping,Dadong,and Dongling,and the district＇s potential population density decreased in sequence of Tiexi,Heping,Shenhe,Huanggu,Yuhong,Dadong,and Dongling.The potential population density was higher in the west than in the east,and higher in the south than in the north.The spatial distribution of residential buildings and population were closely related to the natural condition,economy and infrastructure.The construction of infrastructure in both Tiexi District and city center should be strengthened in the future urban plan,and increase the green space appropriately.Furthermore,the residential land in the south should be increased,and the residential population should be regulated to avoid greater environmental pressure.
