摘要
利用1987年9月26日,1994年8月28日和2001年8月31日3期TM图像对北京市的热岛状况进行了研究,发现从1987到1994年和从1994到2001年,北京的热岛比例一直在增加,但第二阶段与第一阶段比,增加速度有所减缓。
The urban heat island changes of Beijing were studied based on the 3 scenes of Landsat TM data acquired on September 26^th 1987, August 28^th 1994 and August 31^st 2001 separately. It is found that from 1987 to 1994 and from 1994 to 2001 the percentage of the urban heat island of Beijing city was increasing in both periods. But in the second period it did not increase as fast as that of the first period.
