摘　　要：研究了福建省邵武市江南油杉人工林的生长规律和生物量。结果表明,12年生江南油杉人工林树高前期生长较快,随后变慢,在第1年左右达到生长高峰期,10年后树高生长缓慢,胸径生长逐渐加快;乔木层生物量达119.41t·hm-2。The growth of the height, diameter at breast height （DBH） and biomass in 12 years Keteleeria cyclolepis plantation were measured in this paper. The results indicated that the height grew fast in the early years while grew slowly in the late years, and the growth peaks of height was at 1 years age. After ten years the DBH grew fast. There was high productivity level for K. cyclolepis plantation with an annual biomass of 119.41t·hm^-2.
