【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.
[Abstract]:Based on the QuickBird satellite image, the shadow length method is used to measure the urban residential building area, and the characteristics of the potential population distribution in Shenyang city are analyzed in combination with the social and economic statistics. The results show that in 2015, the potential population distribution in the three rings of Shenyang is uneven, and the spatial distribution of the potential population in the third ring presents the typical structure of the circle. The potential population of each administrative region is Dongling District of Dadong District, Huanggu District, Shenghe District, Tiexi District, Dongling District of Dadong District, and the potential population density of each administrative region is Dongling District of Dadong District, Shenghe District, Heping District, Tiexi District. The potential population density in the west of the city is higher than that in the east and in the south is higher than in the The spatial distribution of residential buildings and population is closely related to regional natural conditions, economic conditions and infrastructure construction. In the future urban planning and construction, we should strengthen the infrastructure construction of Tiexi district and central city, increase the number of park green space, rationally develop the residential land in the southern part of the city, and properly control the number of resident population. Avoid causing greater environmental pressure.
