基于热红外遥感的热环境区划研究

Study on Thermal Environment Partition on the Basis of Infrared Remote Sensing

青藏高原的热环境的变化,不仅对我国,对亚洲乃至北半球的大气环流均具有极为重要的作用,直接影响着东亚季风气候的形成和演变。用亚东-格尔木-锡铁山走廊域的地学剖面实测温度数据和青藏高原MODIS遥感影像数据,研究分析了该走廊域的热环境特征。研究表明,在研究区域内热环境分布具有明显的南北条带性:西北部的温度偏低,东南部次之,中东部温度最高。

The changes of thermal environment in Qinghai-Tibet Plateau are very important not only for China, but also Asia and the northern hemisphere atmospheric circulation, which have a direct impact on the formation and evolution of the East Asia monsoon climate. In the paper the thermal environment characteristic of Yadong-Golmud-Xitie Mountain corridor was studied and analysed. The results of study show that the distribution of the thermal environment has obvious north and south strip in the studied area： the northwestern temperature is somewhat low, the southeast is next, and the middle eastern is highest.
