GRASSLAND TYPE AND OVER GRAZED AREA ESTIMATION USING REMOTE SENSING AND GROUND DATA IN MONGOLIA

摘要

The Unvsnuur Hollow is located in westing part of Mongolia and occupies some 30.000 sq(centre dot) km area with specific features covering all the Natural zones of the wold such as desert Gobi, step, forest steppe, lake, glacier and taiga where all biosphere's processes can be reflected.
