摘要: 探讨了不同发育阶段香椿人工林生物量和碳储量的变化规律。对四川省香椿人工林生物量和碳储量进行了调查。研究表明:3 a~24 a生香椿乔木层生物量的变异范围为1.38 t·hm^-2~130.89 t·hm^-2,碳储量的变异范围为0.68 t·hm^-2~64.62 t·hm^-2,1 a~20 a生香椿生物量和碳储量动态变化波动较大,20 a之后呈快速增长趋势,香椿生物量和碳储量均在香椿成熟期达到最大;模拟构建了香椿的树高、胸径和单株立木生物量模型(X表示年龄):H=-0.26X²+1.4338X+0.80936,D=0.01057X²+1.5977X-0.06318,W=0.00315X²-0.03525X+0.09871,其拟合相关系数分别为0.8313、0.9788、0.9971。香椿生物量和碳储量动态变化过程划分了3个阶段,1 a~10 a为香椿幼龄林生物量和碳储量缓慢上升期,11 a~20 a为香椿中龄林生物量和碳储量中速上升期,21 a~30 a为为香椿成熟林生物量和碳储量快速上升期;本文还为香椿人工林碳汇功能提出了合理的林分密度,香椿幼龄期按照初植密度1 666株·hm^-2种植,香椿速生期抚育间伐密度保存在405株·hm^-2,香椿成熟期抚育间伐密度保存在240株·hm^-2为宜。该研究为香椿人工林群落碳汇功能与林分经营管理提供基础资料。

Abstract: To know the changes of different developmental stages of plantation biomass and carbon storage of Toona sinensis in Sichuan Province,investigations were made on the biomass and carbon stock of artificial toona forest.The results showed that 3 years ~24 years old Chinese toona tree layer biomass variation range varied from 1.38 per hectare to 130.89 per hectare,the variation range of carbon storage was from 0.68 per hectare to 64.62 per hectare,the biological amount and carbon storage dynamics change fluctuations of 1 year ~20 years old toona trees were larger,20 years old toona trees had a trend of rapid growth,the biomass and carbon storage reached the maximum in the mature period of Toona sinensis;Simulation was done to build Chinese toona tree height,DBH and individual tree biomass model (X as age):H=-0.26X²+1.4338X+0.80936,D=0.01057X²+1.5977X-0.06318,W=0.00315X²+0.03525X+0.09871,and their fitting correlation coefficients respectively 0.8313,0.9788 and 0.9971.Toona sinensis biomass and carbon storage dynamics change process were divided into three stages.At the age of 1 to 10 Toona sinensis juvenile forest' biomass and carbon stock slowly rose,at the age of 11 to 20 forest biological amount and carbon storage was in a medium speed rise,at the age of 21 to 30,mature forest biomass and carbon storage was in the period of rapid rise.Therefore,this paper put forward reasonable stand density carbon sink function of Toona sinensis plantation,Toona sinensis in the juvenile stage in accordance with the initial planting density of 1 666 trees per hectare should be cultivated,at the toona fast-growing stage the thinning density should concerved at 405 trees per hectare,in Toona sinensis mature period,the thinning density preservation at 240 trees per hectare was appropriate,aiming to provide the basis for the data analysis of the research for the function of carbon sequestration and forest plantations community management.
