摘要
分析了影响中国油松林碳密度的各因子的作用,结果显示,在油松林适生的温度范围内,低温、高降雨量更有利于其积累碳素;随着林龄的增大,气温和降雨量对碳密度的影响作用逐渐减小;天然林和人工林碳密度预测模型分别为:C=-5.107×T+0.079×R+1.263×A(R2=0.895);C=-3.319×T+0.010×R+2.220×A(R2=0.934).
Influence factors of carbon density of Pinus tabulaeformis forest were analyzed in this paper. The results showed that low temperature, high rainfall contributed positively the accumulation of carbon under suitable growth temperature of Pinus tabulaeformis forest and the effect of temperature and rainfall on carbon density decreased gradually in growth. Carbon density prediction models of natural forest and plantation forest were C = - 5. 107 × T ＋ 0. 079 x R ＋ 1. 263×A （ R2 = 0.895） andC=-3.319×T＋0.01×R＋2.220xA（R^2=0.934）.
