摘要
应用IB算法反演厦门市地表温度,整合1996—2013年Landsat-5和Landsat-8卫星影像数据,定量分析厦门市城市热岛的时空变化。结果表明,近20年来厦门市建成区空间分布发生了巨大的变化,热岛的时空演变和建成区的密集度分布基本吻合。
Using the IB algorithm to invert the surface temperature of Xiamen City, the Landsat 5 and Landsat 8 satellite image data from 1996 to 2013 were analyzed, and the spatial and temporal changes of urban heat island in Xiamen were quantitatively analyzed. The results show that the spatial distribution of the built area in Xiamen City has changed greatly over the past 20 years, and the spa- tial and temporal evolution of the heat island and the density distribution of the built area are basically consistent.
