福建武平帽布米槠林择伐经营策略初探　Ⅱ.林分测树因子、物种多样性指数和择伐策略

A Preliminary Analysis on Selection Cutting of Castanopsis carlesii Forest in Maobu, Wuping

通过林分测树因子分析，该林分胸径大于42cm以上的材积比例最大；米槠株数最多、材积百分比也最大，马尾松株数虽少，但材积百分比居第二位．择伐对林分多样性指数的影响不大，伐前、代后近相等.采用皆伐，轮伐期为42年以上，而采用择伐，轮伐期为18年.

Dendrometrical analysis showed that the volume of trees which DBH are over 42cm in this forest occupied the greatest proportion, the species with the greatest number and volume was Castanopsis carlesii, Pinus massoniana ranked second in volume in spit of fewer number. Selection cutting made little effect on diversity. The rotation period was about 18 years if by selection cutting, and it would be 42 years if by clear cutting.
