2种杉木人工林密度与立木生物量的研究
The relationship between stand density and biomass of two rotation Chinese fir plantations
摘要
Abstract
Selecting sampling tree and taking samples from different layer of the sample plots, set on the basis of similar site condition in Chinese fir forest with stand density numbering from 1 300 to 1.500 plants·hm-2 and from2 200 to 2 400 plants· hm-2,located in State-owned forest farms of Baisha and Nanyu of Fuzhou City in Fujian Province, the article analyzes the relationship between stand density and biomass of the Chinese fir plantation. The result indicates that the gross stand biomass increase with the growth of density; the gross stand biomass of high density, at 251.33 t·hm-2, is higher than that of lower density. The biomass of the stem, taking up the 61.87％ of the total, is 154.46 t·hm-2 and outnumbers the stand of lower density by 26％; and the biomass of the root, taking up the 22.85％ of the all, is 57.52 t·hm-2 and outnumbers the stand of lower density by 22％; and occupying the 7.66％ of the all, the biomass of the leaf is only 19.55 t·hm-2 and outnumbers the stand of lower density by 38％. The biomass order of different organs is Wt ＞ Wr ＞Wb ＞ Wl.关键词
