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 .]
