[目的]研究山西黑茶山青毛杨群落物种多样性。[方法]采用样方法进行样地调查,依据重要值指标,应用丰富度指数（N0）、Simpson指数（λ）、Shannon-Weiner指数（H＇）和均匀度指数（E1和E5）进行分析研究。[结果]青毛杨群落物种多样性指数不仅取决于群落的种类组成,而且与种间的重要值配置有密切关系。青毛杨群落内各层物种丰富度指数和多样性指数的大小为草本层〉灌木层〉乔木层;丰富度指数与多样性指数呈正相关关系,而群落均匀度指数的变化与丰富度指数和多样性指数的变化趋势有所不同,且均匀度与优势度呈负相关关系。[结论]进一步了解和认识了青毛杨的生长现状及生长环境,从而为保护这一濒危物种奠定一定的理论基础,同时也为今后濒危物种及相关学科的研究提供基础资料。

[Objective] This study aimed at researching the species diversity of Populus shanxiensis community in Heichashan Mountain. [Method] Based on sampling methods, investigation in sampling spots was carried out according to the important indicator, the abundance index （N0）, Simpson index （λ）, Shannon-Weiner index （H＇） and homogeneity index （E1 and E5） were used for analysis. [Results] Species diversity index of Populus shanxiensis community was not only depended on the species compositions of communities, but also closely related to the important value of species. The order of abundance index and diversity index in each layer of Populus shanxiensis community was herb layershrub layertree layer, and the abundance index was positively related to the diversity index; while the variation trend of community homogeneity index was different from that of abundance index and diversity index, and the homogeneity had shown negative correlation with the dominance. [Conclusion] In this study, the growth status and conditions of Populus shanxiensis were further understood and researched, which had laid theoretical foundation for protecting the endangered species and provided basic information for the future studies of endangered species and related disciplines.
