摘　　要：以海南中部山区的草地、灌丛、次生林和原始林为演替系列,研究植被演替过程中群落结构多样性与物种多样性的变化规律。结果表明,群落演替过程中植物科属种数、总体Shannon-Wiener指数和Margalef指数、乔灌木层的Shannon-Wiener指数和Margalef指数及垂直结构多样性指数都显著增大;群落结构多样性指数分别与群落植物科属种数、总体alpha物种多样性指数、灌木层和乔木层物种alpha多样性指数都显著正相关。通过恢复演替,植被复杂性和质量都呈增大趋势。The patterns of community structure, species diversity, and the correlations between them were explored based on tropical vegetation succession series including grassland, shrub, secondary forest and primary forest in central regions of Hainan Island. Results showed that number of plant family, number of genus, number of species, overall Shannon-Wiener index, overall Margalef＇s index, Shannon-Wiener index and Margalef＇s index of shrub layers and tree layers, as well as vertical structure diversity index, increased from grassland stage to primary forest stage. Community structure diversity was significantly correlated with the number of family, number of genus, number of species, overall alpha species diversity, alpha species diversity of shrub layers and tree layers. These results suggest that vegetation restoration can enhance the complexity and quality of vegetation.
