基于热红外遥感的热环境区划研究

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。

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

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.
