上海市高层建筑的城市热力景观效应研究

以上海市外环线以内为研究区域,运用遥感与地理信息系统技术,建立高层建筑热力景观效应研究的指标体系,分析上海市高层建筑的高度、数量、密度、空间布局形态等对城市亮温的影响,发现高层建筑高度与亮温呈负相关,高度越高,周围的亮温越低;高层建筑集中分布的区域,一般属于亮温的中低温分布区;而高层建筑的数量或密度对热场的影响不大。可见,高层建筑合理布局将有利于减弱城市热场效应。

Study on the Effect of High Buildings on Urban Thermal Landscape in Shanghai

Based on the GIS and remote sensing,this paper analyses the influence of urban high buildings on thermal landscape inside outer ring road of Shanghai.Thermal temperature is influenced by several indices of high buildings such as their distribution,density,spatial form etc.Several conclusions are drawn as follows: 1)The height of high buildings and thermal temperature is negative correlation.2)The region which urban high buildings distributed concentratedly,is the area that the thermal temperature is middle and lower.3)The number and distribution density of high buildings has less influence on thermal temperature.4)Rational distribution of high buildings will weaken thermal effect apparently.
