摘要: 通过对福建青冈Cyclobalanopsis chungii 天然林和人工林的系统调查, 进行福建青冈天然林及人工林生态系统群落特征及生长过程的比较研究。结果表明:福建青冈天然林及人工林群落特征存在明显差异。福建青冈人工林林相整齐, 林分结构简单, 为同龄林, 郁闭度较大, 林下凋落物具有明显的未分解层(L 层)、半分解层(F 层)和已分解层(Y 层)。而福建青冈天然林多为萌芽次生林, 林相不整齐, 为异龄林, 林冠具有成层性, 林下植被生物量大。福建青冈人工林与天然林的生长过程存在明显差异。福建青冈人工林胸径生长峰值出现25 年生时, 而天然林则在24 年生;10 年生前人工林与天然林的树高生长均比较缓慢, 但人工林树高生长进入速生期比天然林早;福建青冈天然林材积生长27 年生后明显增加, 48年生时材积平均生长量与连年生长量仍未相交。人工林15 年生时增长缓慢, 35 年生时材积年均生长量与连年生长量仍未相交。可见福建青冈人工林材积生长比天然林生长表现快, 营造福建青冈人工林是提高其林分生产力的有效途径。图3 参10

Abstract: Through investigation , a comparison between the natural forest and the plantation of Cyclobalanopsis chungii was made .The results showed that there were significant differences in both community characteristics and growth process .Its plantation was even-aged stand , with regular simple form and high canopy density .The litter of the plantation had 3 layers obviously including L , F , and Y .Its natural forest is uneven-aged and secondary stand with irregular form, large biomass of understorey .Besides , the highest diameter growth of the plantation was at the age of 25 , and that of the natural forest was at the age of 24 .The height growth of both increased slowly before 10 years old .The fast height growing period of the plantation was earlier than that of the natural forest .The volume growth of the natural forest increased remarkably after 27 years old .The curves of its annual and average volume growth still didnt meet at the age of 48 .And the volume growth of the plantation increased slowly at the age of 15 . The curves of its annual and average volume growth remained separated yet at the age of 35 .So the conclusion can be gotten that the stand productivity of Cyclobalanopsis chungii could be improved by building the plantation .[ Ch , 3 fig .10 ref .]
