青藏高原札达地区多年冻土遥感技术圈定方法与应用
Remote sensing technology delineation method and its application to permafrost of Zhada area in the Tibetan Plateau
摘要
Abstract
In order to obtain a better understanding of the spatial distribution of permafrost in Zhada area of the Tibetan Plateau,the authors used different remote sensing models to delineate the depth of permafrost and employed elevation model and temperature model to compare the results.According to the result,the study area covers 17 148.93 km2.The authors summarized the interpretation signs for the depth of permafrost in this area.A comparative study of the 3 models can improve the mapping accuracy for the large scale permafrost,greatly reduce related project preceding work and improve efficiency.It is concluded that the application value of the remote sensing technology delineation method is high.Therefore,the remote sensing technology delineation method is very useful in such fields as regional hydrogeology,engineering geology and climate change in the Tibetan Plateau.关键词
