| 摘 要： | 采用哈尔滨市1989,2001,2007年Landsat TM遥感影像资料,利用单窗算法对地面温度进行反演,分析哈尔滨市热场的分布情况,并与20世纪90年代地形图结合来分析道路系统间的温度情况及其与城市热岛的关系。结果表明:铁路和公路温度差异显著且处于不同温度区的铁路温度也有显著的差异;铁路沿线地区热岛效应比较显著,铁路能使周围一定区域温度升高;公路系统作为一种特殊的廊道系统,对城市热岛有一定的阻隔、减缓作用;哈尔滨市铁路对热岛的影响范围不超过300 m,公路对城市热岛的降温作用最大值不超过0.4℃,在120 m以外降低作用很小或没有;绿化率的不同也影响道路对城市热岛的作用效果。

| Abstract: | This paper retrieves the land surface temperature by using Mono-window Algorithm from 1989,2001 and 2007 Landsat TM remote sensing images in Harbin,analyzes the distribution of land surface temperature,the relationship between road system temperature and urban heat island with the topographic map in 1990s.Some research results are as followed: the temperature difference between railway and highway is significant,the temperature in different zones of the railway is also significant different.The heat island effect is evident along the railway and the railway can make temperature rise in a certain region.As a special corridor system,highway can separate and slow down the urban heat island.The effect of the railway in Harbin is no more than 300m range;the maximum cooling effect of highway on urban heat island is no more than 0.4℃,this effect is little or not after 120m.The effect of high way with different greening rate on urban heat island is different. |
