摘要
Ⅱ类地17年生人促米槠林分乔木层地上部分生物量218.2t/hm2,年均净生长量12.835t/(hm2·a);林分平均胸径12.3cm,平均树高16.1m,蓄积量357.8m3/hm2,蓄积平均生长量达21.0m3/(hm2·a);林分叶面积指数8.938m2/m2,叶对树干净同化率117.7g/(m2·a).
The productivity of the 17-year Castanopsis carlesii stand by
artitificial measures promoting regeneration is high.The tree layer biomass on site type II is
218.2t/hm2(above ground).The tree layer net productivity is 12.835thm-2a-1 the mean DBH,height
and volume are respectively 12.3cm,16.1m and 357.8m3/hm2.
