黑龙江省东部山区森林植物多样性结构与动态的研究

Structure and dynamics of forest plant diversity in Eastern mountain area of Heilongjiang province

将森林植物多样性的组成用物种数、集中优势度、物种多样性指数和物种均匀度指数表征,森林植物多样性的结构分为水平结构和垂直结构,水平结构由格局多样性指数表征,垂直结构由垂直结构多样性指数和盖度加权叶层多样性指数表征。结合量化的群落动态,研究了森林植物多样性结构与动态的相关关系。结果表明:群落动态与多样性关系紧密,各植物群落多样性的组成与结构在演替的各个阶段均表现出较大的差异。

The composition of forest plant diversity was represented by total number of species, richness, species diversity index and evenness, meanwhile, the structure of forest plant diversity was divided into horizontal diversity and vertical diversity. The horizontal structure was described by pattern diversity, and the vertical structure was described by vertical structure diversity and coverage weighted foliage - height diversity. The relationship between structure and dynamics of forest plant diversity composing with quantitative community dynamics are researched The conclusion was that there was closed correlation between community dynamics and diversity, and it showed significant difference in every stage of climax about composition and structure of all forest community diversity.
