| Abstract: |
| Using remote sensing imagery data of 1990， 2000 and 2005, and taking the typical oasis in alluvial-dilu-
vial fan/ alluvial-plain type in Bohe and Jinghe Watershed as the study area, the process and trend of oasis LUCC are an-alyzed by applying the methods of remote sensing (RS)，geographic information (GIS) and statistics since 1990. The main results of oasis LUCC in Bohe and Jinghe Watershed from 1990~2005 were as follows:①The change extent of oasis LUCC was that the farmlands increased steadily and the unused lands decreased quickly. Meanwhile, the woodlands decreased in first ten years but increased in the next five years. ②The type conversion of oasis LUCC showed obvious transitional process in bi -direction. But the state of oasis LUCC was quasi balanced in transitional speed.③The deqree of land use had improved . But the trend of that became slow.④The oasis stability became strong but the speed got slow in Bohe and Jinghe Watershed based on the theoretic analysis of the relation that land use affects oasis stability. |
