| 摘 要： | 通过对银杉(Cathaya argyrophylla)生长规律的研究，发现银杉早期生长需要一定的荫蔽，但过分荫蔽导致植株生长缓慢而逐渐死亡。银杉的整个生长过程可分为4个时期，在30～40a内具有明显的胸径生长盛期。银杉单株地上部分生物量的60％分布在1/2树高以下，树干材重量占全部地上部分生物量的比重超过2／3。银杉种群地上部分生物量在不同群落类型间差别很大，介于33000～117000 kg·hm-2。 |

| Abstract: | Young trees of Cathaya argyrophylla grew well in terms of height growth in partial shade condition while less height growth under overshade condition, leading to death finally. The growth process of C. argyrophylla can be devided into 4 stages. The flouring DBH growth was obvious between the age of 30 to 80 years. 60 percent of the aboveground biomass of a sample Cathaya tree was allocated to the portion of below the half tree height. The trunk weighted over 2/3 of the total aboveground biomass. The aboveground biomass of C. argyrophylla population greatly differed among community types and varied from 33000 to 117000 kg·hm-2. |
