摘要: 基于36株碳密度测定样木和5期黑龙江省森林资清查数据(1986~2005),利用非线性度量误差模型来估计黑龙江省落叶松人工林的碳储量动态变化。结果表明:黑龙江省人工落叶松不同器官碳密度在456.7~479.0 mg·g-1之间,不同器官碳密度差异显著,各器官碳密度由高到低为:树叶>树枝>树干>树根。不同林龄落叶松人工林树干、树根树枝和树叶的碳储量分配比例分别稳定在:66.75%~68.92%、21.59%~22.62%、5.99%~8.16%和2.47%~3.50%。其中,树根和树枝含碳量比重随林分年龄增加而增加,树干和树叶含碳量比重随林分年龄增大而减小。1986~2005年黑龙江省落叶松人工林碳储量总体呈增长趋势,2000年时达最大,为30.38 t·hm-2,在此期间,平均每年以1.21 t·hm-2的速度增加。2005年黑龙江省不同区域落叶松人工林碳储量在25.43~34.35 t·hm-2之间,各区域碳储量由高到低依次为:小兴安岭南坡>完达山地区>张广才岭东坡>张广才岭西坡>小兴安岭北坡。

Abstract: Based on the 36 sample trees of carbon storage and data of forest resources continues inventory of 5 periods in Heilongjiang province from 1986-2005, the dynamic change of carbon storage for Larch plantation was estimated by using non-linear error-in-variable model. The results showed that the carbon densities of different organs were 456.7-479.0 mg·g-1 for Larch plantation in Heilongjiang province. The differences in carbon density of different organs were significant. The carbon densities of different organs varied in the following order: leaf>branch>stem>root. The carbon storage ratios of different ages in various organs were 66.75%-68.92% for stems, 21.59%-22.62% for roots, 5.99%-8.16% for branches and 2.47%-3.50% for leaves, respectively. The proportions of carbon storage of roots and branches increased with growing, while those of stems and leaves presented opposite result. On the whole, the carbon storage of Larch plantation in Heilongjiang province has a tendency of increase from 1986 to 2005 and up to the highest of 30.38 t·hm-2 in 2000. The carbon storage increased at 1.21 t·hm-2 during 1986 and 2005 per year. The ranges of carbon storage for Larch plantation in different areas of Heilongjiang province were 25.43-34.35 t·hm-2 in 2005. The carbon storages of different areas varied in the order: Southern part of Lesser Xing’an Mountains>Wandashan Mountains>Eastern part of Zhang Guangcai Mountains>Western part of Zhang Guangcai Mountains>Northern part of Lesser Xing’an Mountains.
