本文简要介绍利用 ＴＭ ６波段能反映地物辐射温度差异这一特点为基础，通过 ＩＨＳ彩色变换 等处理，快速而全面地展示出南京市夏季热量的空间分布状况，为研究城市热岛效应、评估城市 环境质量提供了一种有广泛应用前景的新方法。
In this paper, based on the feature that TM 6 band can reflect the difference of ground object radiation temperature, the spatial distribution of summer heat in Nanjing city is quickly and comprehensively demonstrated by IHS color transformation. In order to study the urban heat island effect, Environmental quality provides a new approach with broad application prospects.
