徐州市城市热岛效应的时空演变分析
nalysis on Spatial and Temporal Variation of the Urban Heat Island Effect in Xuzhou City
本文利用徐州市2000、2003和2007年的Landsat TM/ETM+遥感影像,并基于求出的归一化植被指数(NDVI)结果进行比辐射率纠正,采用基于影像的反演算法,进行地表温度反演,详尽地分析了徐州市城市热岛的时空发展变化特征。结果表明,2000年到2003年徐州市热岛效应逐渐增强,而2003年到2007年间热岛效应呈现减缓趋势;并且从热岛比例指数来看,2003年的热岛效应最为严重。
his paper takes TM/ETM images in 2000, 2003, and 2007 in Xuzhou as main information source, particularly analyzed the space-time change characteristics of urban heat island. Thereinto, we did emissivity correction based on the vegetation index (NDVI) worked out, and surface temperature were inversed by using the inversion algorithm based on image. The results show that, The results showed that the heat island effect gradually increased from 2000 to 2003 in Xuzhou City, while declined from 2003 to 2007; and the heat island effect in 2003 was the most serious from viewpoint of the urban-heat -island ratio index.
