Potential of TM imagery for monitoring and assessment of desertified land

Forest Research 11(6): 599-606

Potential of TM imagery for monitoring and assessment of desertified land

A technical methodology of computer screen interpretation is introduced to produce satellite imagery classification map on an area of about 100 000 km2 of Kerqin Desert in eastern part of Inner Mongol with a mosaic of 6 TM scenes. The potential of remote sensing technique is assessed for change monitoring of desertified land and for environment development tendency estimation. The two problems of salinization and desertification should be treated in different order according to regional situation. The FAO classification and notation principle by land unit, land use and added characters was used in the procedure.

Ecosystem-specific regeneration rates are an important conside...

Human-induced desertification in the Horqin sandy land in the north-eastern part of China has been reversed since the mid-1970s through re-vegetation. This land cover change affects surface energy and water transfer processes. We employed the Bowe...
