The best-fitted equations were adopted for estimating the biomass and its annual growth, and the below-ground biomass and its increment were estimated on the basis of its linear relationship with above-ground biomass. The results showed that the biomass of the branches and of the total above-ground tissues was best described by power-function models, and the best fitted independent variables were d2l and D2H, respectively. The tissue-specific biomass and total biomass of Q. fabri population were all greater in secondary forest than in Pinus elliottii plantation. The above-ground biomass and below-ground biomass of Q. fabri population in secondary forest were 3.592 and 1.723 t x hm(-2), respectively, in which, different tissue components were ranked in the order of stem > branch > leaf; while those in P. elliottii plantation were 0.666 and 0.462 t x hm(-2), respectively, in which, different tissue components were ranked in the order of stem > leaf > branch. From 2004 to 2006, the annual increments of above-ground, below-ground, and total biomass increased with time, and the increment of above-ground biomass had an ascent tendency, which was from 54.35% to 62.20% in P. elliottii plantation and from 67.27% to 68.94% in secondary forest. In comparing with that in secondary forest, the biomass increment of Q. fabri population in P. elliottii plantation was small, despite its relatively high growth rate. %K 白栎 %K 植被恢复 %K 生物量 %K 相对生长方程 %K 年增长量 %K 江西 %K 千烟洲 %K 恢复途径 %K 白栎 %K 种群生物量 %K subtropical %K China %K ecological %K restoration %K different %K population %K Quercus %K 增长速率 %K 趋势 %K 干生物量 %K 天然次生林 %K 湿地松林 %K 总生物量 %K 幂函数 %K 器官生物量 %K 模拟 %K 结果 %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=90BA3D13E7F3BC869AC96FB3DA594E3FE34FBF7B8BC0E591&jid=42FEDDFE54F8BCD9D5FD1926ABDD7722&aid=50136E092A3D2BAD7E31020C338A23AA&yid=67289AFF6305E306&vid=2A8D03AD8076A2E3&iid=38B194292C032A66&sid=3389C664025A98F9&eid=4D4C81DBA842B7BD&journal_id=1001-9332&journal_name=应用生态学报&referenced_num=0&reference_num=34
