| 摘 要： | 据对福建境内30处山地森林样地调查数据,采用 Shannon-Wiener 多样性指数、Simpson 生态优势度与群落均匀度指标,定量测度森林群落的乔木构成水平为物种多样性指数约3～4,生态优势度为0.10～0.25,群落均匀度为0.75～0.90,作者据此探讨了群落的乔木构成特征及其对福建亚热带森林研究与林业实践的意义。

| Abstract: | The paper studies on the quantitative characters of tree organization of forest communities in Fujian,China. The diversity, ecological dominance and community evenness of 30 forest communities in Fujian are measured on the basis of Simpson ecological dominance index, Shannon-Wiener Diversity index and evenness formuta.The results show that species diversity index of subtropical evergreen broadleaved forest is about 3- 4.the ecological dominance is about 0.10- 0.25. the community evenness is about 0.75- 0.90. and the three indexes havean effect on the survey of relative, stability of subtropical forest community. |
