Abstract:: Based on the data of land use change, the temporal evolution and spatial difference of land use structure was analyzed with information entropy theory in mountain area of Longnan from 1996 to 2008. The results showed that the information entropy of land use structure in study area had gone through three development stages: slow growth phase, significant decline phase and rapid recovery phase, the overal entropy presented decline trend, and its land use system tended to become low level ordered state. The regional entropy was significantly different, also their changing trends were varied. Except Wudu District and Liangdang county, whose land-use systems tend to stabilization, others are still remaining in a significant change states.
