摘要
在ArcGIS支持下,定量计算石河子市建筑密度,空间插值后与城市道路和绿地进行叠加分析,结果表明:石河子市建筑密度整体较低,呈现明显的中心分布特征,并向外随距离增加逐渐递减;低密度区面积较大;高建筑密度中心区道路密集而绿地较少;发展迅速的东部开发区将成为新的高建筑密度中心区,使石河子市建筑密度呈现由"单中心"向"多中心"模式发展的趋势,体现了石河子市发展重心的东移趋势。
Based on ArcGIS,the study quantitatively calculated the building density of Shihezi spatialy interpolated,and overlaid with urban roads and green space.The results showed that building density of Shihezi is low in general,with a typical centralized distribution character,decreasing at distance from center to suburbs.Low-density areas are large.The roads are dense and urban green space ratio is low in the centeral area with highest building density.The eastern development zone is expected to be a new high-ednsity centeral area due to its rapid development,making the spatial distribution of Shihezi＇s building density transformed from ＂one center＂ to ＂multiple nuclei＂,and the development center of Shihezi city presented an eastward shift trend.
