Abstract

研究利用2000、2005和2010年逐月的MODIS/Terra和MODIS/Aqua卫星的地表温度数据产品,通过等间距法进行分析,得出成都市建成区2000~2010年间昼夜热岛的时空变化以及相互间差异。研究结果表明:成都市昼夜热岛存在显著差异,日间热岛主要呈散点分布,夜间热岛集中在城市中心区域。日夜间热岛变化趋势有显著不同,日间热岛继续分散而夜间热岛范围则有所扩大。日间热岛分布与植被覆盖存在一定的负相关性,但道路也在一定程度上促使了地面温度的增加,夜间城市热岛范围及变化则与其下垫面组成存在关系。

Other Abstract

Using the monthly MODISTerra and MODISAqua Land Surface Temperature data in the year of 2000, 2005 and 2010, we obtained the temporal and spatial variations of urban heat island during the daytime and nighttime in Chengdu built-up area, and evaluated their differences using the Equal Interval Method. The results showed that: There was significant difference of heat island between daytime and nighttime. Heat island presented a scatter distribution during the daytime and a concentrated distribution in the urban center area during the nighttime. Daytime heat island continued to spread and nighttime heat island scope had widened in the past 10 years. There is a negative correlation between the distribution of heat island and vegetation cover, and the roads also increased the land surface temperature. Nighttime heat island was correlated with underlying surface composition.
