Abstract: From 2013 to 2015, China Aero Geophysical Survey and Remote Sensing Center for Land and Resources leaded the geological survey project “Comprehensive Survey of Land and Resources Using Remote Sensing Technologies in the Northwest Border Area”. As alpine high-altitude and extremely cold area, cryosphere investigation and monitoring using remote sensing techniques in the Northwest Border Area is an important part of the survey works. The research achievements of cryosphere survey are as follows: based on the integrated information such as topography and geomorphology, ground surface temperature, slope and aspect, the permafrost regions have been interpreted in the Northwest Border area; using GF-1 broad width data and Landsat data, remote sensing monitoring about 19 times from Jan, 2013 to Dec, 2014,for the snow cover area, nearly 10 000 km², has been carried out in the west of Ngari Region; lake-ice cover for 6 months in the cold seasons in the Bangonghu Lake and Sipanguerhu Lake area has been monitored using the Landsat image data from 1999 to 2013.
