目标树抚育对亚热带天然次生灌丛群落结构和多样性的影响
Effects of target tree tending on community structure and diversity in subtropical natural secondary shrubs
摘要
Abstract
The typical natural secondary shrub community was chosen in Lin'an of Zhejiang Province to discover its possibility of restoration to arbor forest with three kinds of forest management models being taken,i.e.,no care as control,closed forest management and target tree tending.Over four years growth,compared with control,closed forest management significantly increased average DBH and height by 130％ and 50％,respectively,while 260％ and 110％ for target tree tending.In target tree tending plots,larger trees had been emerging with 4.5-8.5 cm diameter class and 4.5-8.5 m height class and formed a new storey of 4 m compared with control.The species biodiversity indexes at shrub layer were significantly increased in closed management plots,and did not decrease in target tree tending plots.Closed forest management did not change the tree species composition,following its previous succession direction.However,target tree tending increased the importance value of target species with the high potential succession direction of mixed coniferousbroadleaved forest.The results revealed that the secondary shrub community with target tree tending achieved more desired goals on DBH and height growth of dominant trees and species composition improvement compared with closed management.If the secondary shrub community could be managed when the operational conditions existed,target tree tending model should be selected to accelerate the restoration of shrub toward arbor forest.关键词
