林业剩余物资源量评估方法

根据近十年来相关文献报道,分析了前人所建方法的合理性,结合中国林业生产实际,完善了林业剩余物资源潜力的计算方法。主要贡献包括:林业剩余物第二级分类的10个主要类型,即林木苗圃剩余物、林木修枝剩余物、木材采伐剩余物、木材造材剩余物、木材加工剩余物、竹材加工剩余物、薪材、废旧竹材、废旧木材、香蕉和菠萝残体;将经济林采伐和进口原木产生的剩余物计入相关木材剩余物计算范围;首次建立了包括木本水果在内的林木修枝剩余物的计算方法,以及多年生草本水果剩余物即香蕉和菠萝残体产量的计算方法;确定计算公式中参数所需要数据的来源;建议今后重点研究相关系数取值、林业剩余物资源量及其空间分布和相关行业标准等。

Methods for assessing resources of forestry residues

In this study, models for assessing resources of forestry residues were improved based on analysis of previous studies and current forest production in China. And novelties are highlighted: this study covered the models for the calculation of 10 secondary forestry residues from woody nursery, forest woody pruning, wood logging, firewood, wood bucking, wood handling, waste wood, banana and pineapple plants, bamboo processing and waste bamboo; the residues produced from fast-growing forest for logging and processing of imported wood were taken into consideration to calculate woody residue potential; the calculation of pruning residue included woody fruit trees, and herbaceous fruit plants from the management of orchard and other economic forest; the consistency of parameter terminology and definition which referred from their literature resources have been ensured; more studies focused on the coefficient values, industrial standard, forestry residue amount and spatial distribution are recommended for future researches.
