[Objective]To investigate the community biomass and understory plant species diversity in four different restoration models in karst region of Southwest Guangxi in order to accumulate information for biodiversity conservation and the restoration of ecological function in the region. [Method]Four different restoration models were selected as the research object, and the understory plant species diversity were studied by samples, the ground and underground biomass of shrub layer and herb layer was studied by the harvest method; the arbor layer biomass were studied by using allometic models and the ratio of root and stem recommended by IPCC. [Result]85 species belonging to 81 genera of 47 families were recorded, among of which, 50 species belonging to 46 genera of 25 families were shrubs and 35 species belonging to 35 genera of 22 families were herbs. The biomass of different vegetation restoration models showed that the highest was the natural restoration forests (166.66 t·hm-2) followed by Zenia insignis fores
