Biomass and Net Primary Productivity of Larix olgensis Plantation in Bingla Mountains, Northeast China
摘要
Abstract
There is a close relationship between forest biomass and fixed carbon of forest ecosystems. In this paper, a group of allometric growth equations were established to estimate the allocation patterns of biomass and net primary productivity at 4 different ages in Larix olgensis plantations located in Bingla Mountains (Northeast of China). The main results are as follows: (1) Total biomass of community at different vegetative stages were 154.0t-hm"2, 179.3t-hm-2, 229.4t-hm-2 and 254.8 t-hm-2 for juvenile, middle-aged, near-mature and mature stand respectively. And the proportions of arbor were more than 94%. The net primary productivity of arbor were decreased with stand age, it could up to 16.71t-hm-2·a-2 for juvenile which was higher than the productivity of mature forest near 1 times. The average proportions of different organs of the total productivity in all stand ages were in sequence of leaf (46%)> stem (39%)> root (10%)> branches (5%).关键词
