摘　　要：以福建省安溪丰田国有林场的福建柏马尾松混交林为研究对象,探究了基于7种不同强度抚育间伐的福建柏人工林生长效果,为抚育间伐后的林分经营提供管理策略。结果表明:基于抚育间伐的7种福建柏林分中福建柏胸径、树高、冠幅、枝下高和单株材积差异性达到极显著水平。试验林5的福建柏胸径、树高、单株材积均在不同福建柏林分中最大,而试验林1和试验林2的福建柏胸径、树高、冠幅、单株材积均在不同福建柏林分中较小,所有林分中福建柏冠幅均在2.10~2.86 m。试验林1~6经过抚育间伐后,福建柏胸径、树高、单株材积生长量都很大程度提高了,其中,间伐强度35%处理后的福建柏胸径、树高、单株材积生长最快。一元材积公式计算的试验林1~7单株材积均大于二元材积公式计算的单株材积。利用主成分分析,得出基于不同强度抚育间伐的7种福建柏试验林中,试验林4、试验林5的福建柏生长效果最好。Taking Fokienia hodginsii-Pinus massoniana mixed forest in Anxi Toyota State-Owned Forest Farm in Fujian Province as the research objects,this paper explores the growth effect of Fokienia hodginsii plantation based on cultivate thinning of different intensities,and provides management strategies for forest stand management after tending and thinning.The results showed that the differences in diameter at breast height,tree height,crown width,under-branch height and volume of per plant of Fokienia hodginsii among the seven species of Fokienia hodginsii based on tending thinning reached a very significant level.The DBH,tree height,and volume per plant of test forest 5 were all the largest in different Fokienia hodginsii plantation,while the DBH,tree height,crown width,and volume of per plant of test forest 1 and 2 were all in different Fokienia hodginsii plantation.The forest is relatively small,and the crown width of Fokienia hodginsii in all stands is 2.10~2.86m.After tending and thinning of test forests 1 to 6,the DBH,tree height,and volume growth per plant of Fokienia hodginsii were greatly improved.Among them,the DBH,tree height and single plant wood accumulation of the test forests 1 had grown the fastest after thinning intensity of 35%.The volume of test forests 1 to 7 per plant calculated by the one-element volume formula was calculated by the two-element volume formula.Using principal component analysis,it was concluded that among the 7 test stands based on tending and thinning,test forest 4 and test forest 5 has the best growth effect.
