摘要
1990年在凉水自然保护区对31年生黄波罗红松人工混交林的生长量、林分状况及生物量等进行了调查研究。结果表明:31年生黄波罗林生长仍处于旺盛时期;黄波罗在混交林中的生长状况比在纯林中要好,黄波罗在混交林中病腐率为25％,而在纯林中达40％。黄波罗红松人工混交林群落总生物量为73.53t/ha,其净初级生产力为3.12t/ha·a,与其它林型相比,黄波罗红松混交林净初级生产力处于较低水平。
The stand growth,stand state and biomass of Phellodron amurens and Pinus koraiensismixed stand of 31 years old were investigated and analyzed. It showed that the stand was also in the stage of vigorous growth for 31 years old. The stand state of Phellodendron amurense is better in mixed stand than that in pure stand. The branching and damage percentage of Phellodendron amurense in pure stand is 40％.But it is only 25％ in mixed stand. The total biomass of Phellodendron amurense and Piuns koraiensis mixed stand is 73.53 T/ha. The net primary productivity is 3.12T/ha.a. Compared with other plant communities,the mixed stand possessed relatively lower productivity.
