Abstract: In order to structure a multi-object and stable forest ecosystem, improve the biodiversity of local ecosystem, maximize the potential of biological resources, and provide technical support for forest development,this paper discussed the effects of economic plant compound management modes on community species diversity of low quality and low efficiency secondary forest in Mudanjiang. Based on the survey data, species richness index, evenness index and diversity index were used to analyze the status of community species under different complex management modes. The study found that:（1） 71 species of higher plants were investigate under the secondary forest, belonging to 21 genera and 37 families;（2） The species diversity index of the compound management modes were lower than that of the control;（3） The species richness and Simpson index of different life forms in the compound management mode were higher in the herb layer than in the shrub layer than in tree layer.（4） There were no significant differences in the effects of different compound manage modes on the species diversity index. These results indicated that the above ground community structure would be changed by the compound management mode, and the initial performance was disturbance, which would gradually improve the species richness and resource utilization efficiency, and restore the ecosystem function.
