摘　　要：通过采用修枝强度30%、40%、50%和不修枝四种处理方式对福建柏(Fokienia hodginsii)人工林进行实验,分析不同修枝强度对福建柏生长指标的影响,旨在为福建柏人工林制定合理的经营管理措施提供依据。结果表明:随着修枝强度的增加,福建柏的胸径、树高、高径比、单株材积和生物量均有所增加,当修枝强度为50%时,各项指标值最大,分别为7.83 cm、6.84 m、87.40%、0.018 m3和27.80 kg。The effects of different pruning intensity on the growth index of Fokienia hodginsii plantation were analyzed by using 30%,40%,50%and no pruning.The purpose of this study was to provide a basis for the development of reasonable management measures for Fokienia hodginsii plantation.The results showed that the DBH,tree height,height-diameter ratio,individual volume and biomass of Fokienia hodginsii increased with the increase of pruning intensity.When the pruning intensity was 50%,the values of each index were the largest,which were 7.83 cm,6.84 m,87.40%,0.018 m3 and 27.80 kg,respectively.
