摘要/Abstract

摘要： 采用先进的遥感手段,能够大面积同步和动态地监测地面热场的分布和变化情况。利用长春市地区的LANDSAT图象,对于热红外波段遥感图象灰度值和地面温度之间的关系进行了定量的解译,并且采用TM6图象增强和密度分割的方法得到了长春市地面热场等级图,取得了很好的模拟效果。结果显示了长春市热场的分布具有明显的规律性。城市能耗和下垫面性质对于区域温度有直接的影响,此外,还结合图象分析了热场分布的形成因素。

Abstract: With the rapid development of urbanization, problems caused by heated-island influence in big cities have become more and more serious and unneglectful than ever before. It is necessary and useful for city planner and managers to investigate rapidly and effectively the distribution, intension and effective factors of heated-island in these cities. By means of advanced remote sensing, the distribution and change of ground heat field can be monitored synchronously and continuously. In this paper, Changchun was investigated as an example. A correlation model was built between ground temperature and image brightness of LANDSAT TM Band 6,and a map of ground heat field was made by image enhance method and the density partitions. Results show that the heat field of Changchun presents regular distribution. It is also found that the distribution of city energy-consuming and landcover affects directly the upper ground temperature. In the end of the paper, several factors influencing the heat field of Changchun City are also analysed.
