摘要:

连续7 ~8a 的固定标准地调查结果表明:利用人工促进天然更新可成功培育短伐期闽粤栲林、短伐期米槠林及短伐期丝栗栲林,轮伐期分别为10 、14 及16a ,达轮伐期时的蓄积平均生长量分别高达20-52 、15-99及12-17m3/(hm2·a) :短伐期林分密度大、自然稀疏强烈,高生长异常迅速,高径比大、树枝树叶比例较小,生产力高;短伐期林分均为多树种(12 ~17 种) 混交的单优群落,灌木层中的乔木幼树多样性高、密度大。

Abstract:

A continuous inventory by permanent sample plots for 7~8 years showed:Castanopsis fissa stand of short-rotation, Castanopsis carlesii stand of short-rotation and Castanopsis fargesii stand of short-rotation had been successfully cultivated by natural regeneration with artificial promotion.Their rotations were 10,14 and 16 years,respectively.Their mean annual increments of growing stock at rotation age were 20.52,15.99 and 12.17m3/(hm2·a),respectively.High density,strong natural thinning,rapid height increment,high ratio of height to DBH,low percentage of tree branch and leave and high productivity were the features of the short-rotation stands.

Key words: Short-rotation, Broad-leaved forests, Castanopsis fissa, C.carlesii, C.fargesii
