Abstract

The research on ice-snow gained the concerns of a lot of researchers in ecology, geography, meteorology and so on in the past years, and a series of achievements in scientific research has been gained. Especially, remarkable advances have been made in ice-snow science after the application of remote sensing techniques. A snow mountain area in Qinghai-Tibet Plateau was chosen as the study area. The DEM was constructed by use of the peculiar stereo data collection function of HRS on SPOT5. The three-dimensional (3D for short) monitoring model was set up, and the superficial area was computed based on the TIN model. At last, the authors synthetically estimated the ice-snow resources status combining to the results gained before. The aim of this study is to provide theory and scientific evidence for the efficient management of ice-snow resource, and furthermore provide scientific evidence for the macroscopical adjust and control of water resource and sustainable development in China.
