4) second generation
二代
1.
The community structure, tree species composition, biodiversity and diameter structure of Castanopsis carlesii forest (8-year old) by AMPR(artificial measures promoting regeneration) of first generation after clear-cutting are similar to the second generation(6-year old).
皆伐形成的一代(8a生)和二代(6a生)人促米槠林的群落结构、组成树种、物种多样性、直径结构等均相近;但一代人促米槠林以有性(实生)起源为主,二代人促米槠林以无性(萌芽)起源为主,二代林分生产力明显大于一代林分,充分体现萌芽更新的早期速生性。
2.
The community and measuration features comparison between 8-year old first and 6-year old second generation stands in the same plot showed: Two stands structure were similar.
同一地林块８年生一代和６年生二代人促闽粤栲林分群落学特征及测树学特征对比评价结果表明：两代林分群落结构相近；二代林分乔木层物种多样性指数、均匀度比一代林分略大；二代林分生产力较一代林分的低，但仍保持较高的生产力。
