Abstract:Sandy desertification disaster is one of the most serious disasters which endanger sustainable development in arid, semi-arid, and semi-humid zones in China. Now, the area of sandy deserti-fied land in China is 201 thousand km2, its annual direct loss is 1. 74 - 2. 04 billion yuan, the total annual loss is 78. 3 - 91. 8 billion yuan. Among 212 counties affected by sandy desertification disaster there are 123 slight degree counties. 54 middle degree counties and 24 severe degree counties. With the development of sandy desertification disaster in the future, it is predicted that the area of sandy desertified land will reach 233 thousand km2 in '2000, the sandy desertification disaster degrees of 107 counties will go up. the sandy desertification disaster degrees in China will become 46 slight degree counties. 123 middle degree counties and 43 severe degree counties.
Keywords:Sandy desertification disaster Status Development trend
