摘要:

作者设计和实现了基于树木年轮信息动态估算树木材积生长量模型TGTRing。利用该 模型动态估算了中国红壤丘陵典型区千烟洲三种人工林乔木层的生物量和碳蓄积量。结果表明: 马尾松的年生物量和碳蓄积量的增长曲线分别在林分年龄17 年和18 年左右开始出现拐点, 湿地松、杉木的年生物量和碳蓄积量则均在林分年龄15 年左右开始出现拐点; 20 年的 单位面积生物量和碳蓄积量杉木林最高, 分别为171.697 t/hm2 和92.29 tc/hm2, 其次为湿地松 林, 分别为147.639 t/hm2 (未割脂) 和135.743 t/hm2 (割脂)、80.18 tc/hm2 (未割脂) 和73.72 tc/hm2 (割脂), 马尾松林最低, 为133.84 t/hm2 和73.92 tc/hm2; 平均年生物量和碳蓄积量杉木 林最高, 分别为8.58 t/hm2/yr 和4.61 tc/hm2/yr; 湿地松林次之, 未割脂和割脂湿地松林生物 量分别为7.38 和6.76 t/hm2/yr、碳蓄积分别为4.01 和3.69 tc/hm2/yr; 马尾松林最低, 分别为 6.69 t/hm2/yr 和3.70 tc/hm2/yr; 到2006 年为止, 千烟洲马尾松林乔木层总生物量和碳蓄积量 分别为3324.43 t、14156.64 tc, 杉木林分别1326.97 t、713.27 tc; 湿地松林按未割脂算分别 为14156.64 t 和7688.21 tc, 按割脂算分别为13015.97 t 和7068.78 tc; 千烟洲湿地松人工林 因为割脂原因, 乔木层总生物量损失1140.67 t, 总碳蓄积量损失619.43 tc。

Abstract:

The authors developed a model to estimate annual tree growth based on tree-ring data (Abbr. TGTRing model) derived from the trunk at 0.5 m, 1.3 m and 2.5 m height. This model was applied to estimate the annual biomass and carbon accumulation of a plantation in Qianyanzhou Red-Soil Hill Comprehensive Development Experimental Station of CAS in Taihe County, Jiangxi Province (Abbr. Qianyanzhou). The results showed that the inflexion points of the biomass and carbon accumulation curves occur at 17 and 18 years of age, respectively, in Masson pine, whilst both inflexion points occurred at 15 years in slash pine and Chinese fir. The biomass and carbon accumulation in Chinese fir proved to be greater in the last 20 years than in the other species, with 171.697 t/hm2 and 92.29 tc/hm2, respectively. Masson pine, with a biomass of 133.84 t/hm2 and a carbon accumulation of 73.92 tc/hm2, was the lowest whilst slash pine was intermediate with a biomass of 147.639 t/hm2 (unturpentined) and 135.743 t/hm2 (turpentined), and a carbon accumulation of 80.18 tc/hm2 (unturpentined) and 73.72 tc/hm2 (turpentined). In 2006, the total biomass and carbon storage of the tree stratum of Masson pine in Qianyanzhou was 3324.43 t and 14156.64 tc, respectively, whilst the values for Chinese fir were 1326.97 t and 713.27 tc. For slash pine was the total biomass was 14156.64 t (unturpentined) and 13015.97 t (turpentined), and the total carbon storage was 7688.21 tc (unturpentined) and 7068.78 tc (turpentined). Following the shaving of slash pine for resin, the total biomass was reduced by 1140.67 t and the total carbon storage fell by 619.43 tc.
