Abstract: In this study, based on the land-use change data of representative desert oasis in Jintai county of Gansu province from 2006 to 2008 and by using methods of quantitative analysis on indices of landscape ecology, i.e., the diversity index, the evenness index and the dominance index, analysis on the differentiation of land use structure in the study area and analysis on the oasis stability in combination with field survey of planting structure adjustment on land productivity and economy were conducted. The result showed that the landscape heterogeneity decreased, the landscape components tended to be heterogeneous distribution, the dominant patch's control role on landscape strengthened, and the stability of oasis enhanced from 2006 to 2008.
