| This research focused on the investigation into the vegetations of coal mine subsided areas of Shenfu-Dongsheng Coal Mine Region in different years and landforms. Based on the data obtained from the field survey, importance values of the plant species and plant diversity indexes were calculated. The findings showed that plant species in the region were relatively poor because of the fragile ecological environment. There were 114 species found in the investigated areas belonging to 82 genera, 30 families. The plant species in Shangwan, Daliuta and Huojitu mines were richer than those in Bulianta and Ulan-mulun mines. After subsiding disturbance, the main components and the constructive species of the plant communities did not changed in the short term. Species diversities in all mining areas, except Ulan-mulun mine where the ecological environment is much more fragile, showed no significant differences. Numbers of plant species in subsided plots were more than those in the undisturbed areas. Numbers of plant species in the plots subsided within 1 year were more than those in the plots of subsided for 1 year, which indicated that the ground subsidence caused by coal mining slightly influenced the community composition within short period. The plant communities was to stabilize after 2 years in the plots subsided...
