Abstract

Desertification is one of the most serious environment and socioeconomic problems in the world and China today. Land of sandy desertification almost covers everywhere in Ejin Banner (County), Inner Mongolia. Using remote sensing method can expediently acquire some information such as desertification’s status, and effect of harnessing desertification. In this paper, ecological change situation from 1986 to 2000 in Ejina Oasis is researched. The result is followed: (1) Area of water body of Lakes in Northeastern Ejin Banner are distinctly reduced. (2) Area of the oasis is rapidly shrunk. From 1986 to 2000, the area is reduced 61.48%, average 4.39% annually. (3) Condition of oasis growing is declined. The oasis’s ecological environment trends to bad. Its main reason is what human activities exceeded the load capacity of natural resources such as water and land. By means of self-restorative ability of natural vegetation and human’s scientific conservation, that the oasis’s ecosystem maintains dynamical balance and the environment recovers is possible.
