| 摘 要： | “热岛效应”现象是现代城市气候的主要特征之一。利用TM卫星遥感数据的分析结果,根据地理相似准则,提出以相对亮温来表示热岛强度,并将此无量纲因子应用于比较不同城市同一的不同小区;或同一小区不同时期中的热岛强度的差异,以此探讨利用遥感技术监测城市热岛强度的可能性。并提出将城市热岛强度作为城市生态环境状况的监测指标之一。

| Abstract: | Urban Heat Island" effect is one of features in the modern city. In this paper, it is studied to monitor the intensity of urban heat island with LANDSAT data. Based on the geographic similitude rule, the comparative light temperature was taken as the intensity of heat island. Comparing the differences among intensities of heat island in five cities at the same season and one city at the different seasons with this dimensionless factor,it is feasible to monitor the intensity of heat island effect by using remote sensing data. Therefore, it is reasonable taking the intensity of heat island effect as a monitoring indicator of urban ecosystem. |
