单窗算法在武夷山市地表温度反演中的应用

Land Surface Temperature Retrieval of Wuyishan City by Mono-window Algorithm

基于2004、2009、2013年的Landsat系列遥感影像,应用单窗算法反演武夷山市相应时点的地表温度,采用均值-标准差法对地表温度反演结果进行分级.结果表明:武夷山市的地表温度分布呈现出由市区中心向四周逐渐降低的趋势,市区主要交通干线及其周围一定区域内地表温度较高,距离交通干线越远,地表温度越低;2004-2013年武夷山市高温区域面积扩大,热岛效应逐步增强.

Based on a series of Landsat remote sensing imagery of 2004, 2009 and 2013, LST（Land Surface Temperature ） of Wuyishan city during the 3 years was retrieved by Qin Zhi-hao ’ s Mono-window Algorithm and the result was classified by average-standard deviation .The results showed that the surface temperature of Wuyishan city reduced gradually from city center to the surrounding areas ; from the changing characteristics it could be seen that the LST in the main traffic arteries and its surroundings were higher than the other areas ;the farther the distance from the traffic route , the lower the temperature would be .Compared with the former two LST results, there was a wider area of high temperature in 2013.From the year 2004 to 2013, the high temperature area in Wuyishan city had expanded to a certain degree , and the urban heat island effect had become more serious than before .
