摘　　要：对27年生保留密度分别为425、725和825株·hm^-2的福建柏人工林生长量及其经济效益进行分析,初步筛选出经营利润最高的保留密度。结果表明:福建柏人工林的平均胸径、平均树高、平均单株材积和大径木的数量随保留密度的增加而降低,平均蓄积量先增后降;福建柏主伐规格材和非规格材的出材量、总出材量、总产值以及经营利润随保留密度的增加先提高后减少。保留密度为725株·hm-2的林分蓄积量、总出材量及经营利润均最高。The growth and economical benefit of 27-year-old Fokienia hodginsii plantation with the density being 425,725&825 trees·hm-2 were studied to be selected the density with the optimal of operating profit.Result shows that average DBH,average height,average individual volume&number of big DBH wood of Fokienia hodginsii plantation were reduced with the increasing of density as well as the average stand volume increase first and then reduce.The output of final felling dimension stock and anti-dimension stock,total output,total output value&operating profit of Fokienia hodginsii plantation increase first and then reduced.The forest stand with the density of 725 trees·hm-2 have the optimal stand volume,total merchantable volume&operating profit.
