摘　　要：以江西井冈山国家级自然保护区内的罗浮栲为研究对象，利用典型样地选择、每木检尺及树干解析等方法，对罗浮栲的生长过程及各器官生物量分配情况进行了初步研究。结果表明：罗浮栲胸径连年生长量为0～10、30～40 a，胸径生长迅速，连年生长量高峰达0．585 cm，60 a 胸径达到27．2 cm；罗浮栲高生长量在30 a 达到9．80 m，成为优势木；罗浮栲材积生长量在0～20 a 生长缓慢，20～60 a 一直处于快速生长阶段，连年生长量60 a 达到0．0226 m3；罗浮栲平均生长量与连年生长量曲线没有相交，说明罗浮栲到60 a 还未达到数量成熟龄。罗浮栲的生长发育分3个时期，0～20 a 为幼龄期，20～50 a 为速生期，50～60 a 为壮龄期。This article took the Jiangxi Jinggangshan National Nature Reserve of Castanopsis fabric as the re-search object,through the use of typical sampling,each wooden foot and trunk analysis and other methods,to under-take preliminary study of Castanopsis fabri growth and biomass allocation pattern.The results showed that,at two Castanopsis fabri growth periods：0 -10 a,30 -40 a,DBH growth in successive years was rapid,the peak of 0.585 cm.DBH of 60 a reached 27.2 cm.Castanopsis fabri tree height growth in 30 a to 9.80 m,become the dominant tree;Castanopsis fabri volume in 0 -20 a was slow growth,yet 20 -60 a has been a rapid growth phase,annual growth volumeof 60 a to 0.022 6 m3 .Castanopsis fabri average growth rate and the annual growth volume curves did not intersect,indicating that Castanopsis fabri of 60 a also did not reach maturity age.The growth of Castanopsis fabri was divided into 3 periods：0 -20 a for the juvenile stage,20 -50 a for a fast-growing period,50 -60 a for strong age.
