摘要
林分水平的计量数表是开展森林资源二类调查必不可少的度量衡。利用黑龙江省国家森林资源清查的53个人工落叶松(Larix spp.)样地实测数据,结合已经颁布实施的《落叶松立木生物量模型及碳计量参数》行业标准,建立了林分水平的基于断面积和平均高的蓄积量、生物量和碳储量模型。结果表明:所建模型的确定系数(R2)在0.91以上,平均预估误差(MPE)在4%左右,可以满足森林资源二类调查的精度要求;提出的建模方法,也适用于建立其它地区或其它树种的林分蓄积量、生物量和碳储量模型。
The stand level tables and models are indispensable tools for implementing forest management inventory.Using the mensuration data of53larch(Larix spp.)plantation plots of national forest inventory in Heilongjiang province,and combining with the published ministerial standard Tree Biomass Models and Related Parameters to Carbon Accounting for Larix,stand level models of stock volume,total biomass and carbon storage based on basal area and mean height were developed in this paper.The results showed that determination coefficients(R2)of the developed models were more than0.91and mean prediction errors(MPE)were less than5%,which could meet the precision requirement for forest management inventory.The presented approach is suitable for developing stand level models of stock volume,total biomass and carbon storage for other tree species in any regions.
