| Abstract: | In order to study the plant composition and diversity characteristics of Gleditsia microphylla community in Daqing Mountain area of Jingxing County, the study took G. microphylla community in the low mountainous area of Jingxing County in the middle of Taihang Mountain as the research object, used the sampling method to analyze the plant composition and diversity characteristics of the community, which provided a theoretical basis for the ecological restoration, development and utilization of G. microphylla shrub. The results showed that there were 30 species of G. microphylla community in Daqing Mountain area of Jingxing County, belonging to 19 families and 28 genera. In terms of plant composition, Poaceae, Gramineae, Leguminosae and Asteraceae, the dominant species were Carpinus turczaninowii, Gleditsiamicrophylla, Vitex negundo, Carex and Selaginella sinensis. In terms of diversity index, the diversity index and richness of shrub layer and herb layer were higher than those of tree layer. The evenness and dominance of tree layer were higher than those of shrub layer and herb layer. |
