| 摘 要： | 根据湖南碳汇项目林主要类型,充分利用"八五"-"十二五"期间课题组自有成果,同时开展补充调查,以项目林28个主要建群种为研究对象,依据立地条件、林分类型、群落结构、林龄等因素综合布设386个固定样地,按径阶组分不同的树高级选取目标径阶标准样木2 139株,实测标准木生物量,利用11种形式的生物量模型分别对各树种单株生物量进行拟合,得出拟合效果最优的单株生物量模型,通过评价与检验,各模型均具有较好的拟合精度和预估水平。

| Abstract: | Based on properties of forest community and species distribution of project forests of carbon sink,making full use of own achievements of the studying team between the Eighth Five-year and Twelfth Five-year Plan period,at the same time to carry out the supplemental investigation,386 typical sample plots were set up according to the climatic re-gion,site conditions,stand type,community structure,age composition of stand,and standard trees were surveyed for biomass in the area. 2 139 goal diameter-class standard trees were selected according to diameter-class groups of different tree-height grades,and their biomass were measured. The total of 1 1 kinds of biomass models were adopted to estimate average biomass,and the optimal fitting effect of average biomass models were concluded,with advantages of easy obtain of indicators and good fitting precision and estimation level. |
