摘要：选择西双版纳勐腊县境内典型的季节性雨林和山地雨林两个植被类型进行林分直径结构研究.结果表明:热带雨林不划分林层时直径分布为左偏,偏度和峰度值均较大;划分林层后,各层直径分布都遵从三参数的Weibull分布函数,C层同时遵从迈耶负指数分布函数,偏度和峰度系数均与林分直径成反比.
The typical ravine rainforest and the mountainous rainforest in Xishuangbanna Nature Reserve in Mengla County were selected as objectives for diameter structure research. The results showed that the diameter distribution of the tropical rainforests was left bias before the stories were divided, and both the skew and kurtosis values were large. While the diameter distribution in each storey well followed the three-parameter Weibull distribution function, and the C storey also followed the negative index distribution function proposed by Meyer after the stories were divided, and both the skew and kurtosis coefficients were inversely proportioned to stand diameters.
