热惯量填图与冻土研究

Thermal inertia mapping and permafrost study

详细地介绍了热惯量填图技术在多年冻土研究中的应用。研究中利用MODIS卫星图像的数据,借助热惯量方法对青藏高原东北部的多年冻土进行了分析。其结果表明,由热惯量图像所圈定的冻土范围与常规野外调查方法的结果极为吻合。

This paper introduces the application of the thermal inertia mapping technique in permafrost study. In the study, the authors used the MODIS satellite image data and the thermal inertia method to analyze the permafrost on the northeastern Qinghai-Tibet Plateau. The results show that the areal extent of the permafrost distribution delineated by the thermal inertia images is very coincident with the results of conventional field investigation.
