Studying the spatial differences of land use degree evolution is of significance for mountainous areas to make polices according to local conditions. In this study, ArcGIS and GeoDa software were used for processing data resources, and we used the spatial autocorrelation method to analyze global spatial differences and local spatial disparities of cultivation coefficient, proportion of construction land and integrated index of land use degree in Guizhou-Guangxi karst mountainous areas from 1990 to 2010. The results are as follows. (1) During 1990—2010, the global spatial phenomenon of cultivation coefficient, proportion of construction land and integrated index of land use degree changes had a significant cluster in Guizhou-Guangxi karst mountainous areas. The agglomeration of integrated index of land use degree change had increased, on the contrary, the agglomeration of cultivation coefficient and proportion of construction land had declined. (2) During 1990—2010, the global spatial phenomenon of cultivation coefficient was agglomerated on the whole, but its local difference enhanced. Local spatial regions with ‘high—high’ correlation were mainly located in the north area, however, other regions with ‘low—low’ correlation distributed in the middle area. The local temporal changes of cultivation coefficient kept relatively stable. (3) From 1990 to 2010, the global spatial agglomerated phenomenon on the whole of proportion of construction land reduced, on the contrary, its local difference increased. Local spatial regions with ‘high—high’ correlation mainly were located in the south area, however, other regions with ‘low—low’ correlation distributed in the middle area. The local difference which was significant distributed in the north area, middle area and south area on the temporal change of proportion of construction land. (4) From 1990 to 2010, the global spatial phenomenon of integrated index of land use degree was agglomerated on the whole and slowly strengthened. Local spatial regions with ‘high—high’ correlation were mainly located in the south area and north area, however, other regions with ‘low—low’ correlation distributed in the middle area. The local difference on the temporal change of integrated index of land use degree was significant, which distributed in the north, middle and south area.
