Selection cutting management of Castanopsis fargfesii community in Maobu of Fujian Province

This paper deals with age structure , growth process and dendrometrical analysis of dominant species with importance value more than 10 in Castanopsis fargesii community in Maobu , Fujian .The results showed that Castanopsis fargesii , Machilus pauhoi , Castanopsis nigrescence , Cinnamomum micranthum ,Daphniphyllum oldhamii , Cyclobalanoposis glauca , Castanopsis juncunda , Phoebe bournei belonged to stable populations , and Cunninghamia lanceolata and Pinus massoniana belonged to decline populations .Castanopsis fargesii had the highest increments in height and diamenter at the age of 30 ～ 36 years and 36 ～ 40 years respectively .The volume growth of Castanopsis fargesii speeded up at age of 26 years , but didnt reach the highest increment before 40-year-old .The volume of trees with the DBH more than 42 cm in this forest occupied the greatest production .The species with the greatest number was Castanopsis fargesii .Pinus massoniana ranked first in volume in spite of fewer number .Selection cutting made little effect on diversity .The rotation period was about 18 years if by selection cutting , and it would be 42 years if by clear cutting .
