Measurement of the Species Diversity of Forest Communities in the North Fujian

  • 摘要: 采用8个物种多样性指数对闽北地区的8个森林群落类型物种多样性进行测定,并选用4个种-多度关系模型(对数正态分布、Weibull分布、对数级数分布、生态位优先占领模型)分析其物种-多度关系,把多样性指数与对数正态分布、Weibull分布和生态位优先占领模型的有关参数进行线性回归,以分析多度模型参数描述物种多样性的可行性。结果表明:(1)多数物种多样性指数对群落的测度是一致的;(2)对数正态分布、Weibull分布和生态位优先占领模型对8个群落的物种多度拟合效果很好;(3)对数正态分布、Weibull分布和生态位优先占领模型有关模型参数与部分物种多样性指数的线性关系达显著或极显著水平。通过闽北地区8个类型森林群落物种多样性指数测定,使生物多样性较准确地数量化,同时还说明采用改进单纯形法进行非线性分布函数的拟合是简单有效的,可推广应用。
    Abstract: Eight types of forest communities in the north Fujian were studied with 8 species diversity indices and 4 species-abundance relationship models, which are log normal, Weibull distribution, log series, niche preemption models, were used to analyze species-abundance relationship, and the regressions between diversity indices and the parameters about log normal, Weibull distribution and niche preemption models were also studied in order to analyze the probability of describing the species diversity by the parameters of abundance models. The results showed that most of the diversity indices reflected the community’s characteristics, and that eight communities could be fitted well with log normal, Weibull distribution and niche preemption models. The strong or very strong linear correlations exited between the parameters about some of the models and the diversity indices. The results also showed that the bio-diversity could be quantified by the measurement of the species diversity of 8 forest communities in the north Fujian and that modified simplex was a simple and effective method and could be popularized to apply.
