林业剩余物资源量评估所用系数的定义和取值

Definition and assessment of coefficients for the calculation of forestry residues

摘要:

有机废弃物是重要的待开发利用的生物质资源，特别是发展生物炼制。文中针对林业剩余物第二级分类的全部10个类型，根据1993–2017年间报道的有关林业剩余物系数研究，首先在前人研究结果的基础上，完善了系数体系及其定义。然后，对以前的取值通过文献溯源甄别其合理性，对于没有明确依据的取值和迄今未取值的系数，通过相关研究获得数据并进行实地调研，确定了计算林木苗圃剩余物、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、废旧竹材和废旧木材、香蕉和菠萝残体所需系数的合理取值。

Abstract:

Organic waste is an important biomass resource. In this study the definition of coefficients for the calculation of all the secondary 10 forestry residue categories was improved and established according to literature reviewing of previous reports between 1982 and 2017. The rationality of value-taking for each coefficient in previous literature was examined by tracing to its citation sources. The irrational, or unstudied coefficients were assessed using the data in previous reports or questionnaire surveys. Lastly, values of the coefficient for the calculation of woody nursery residue, forest woody pruning residue, wood logging residue, firewood, wood bucking residue, wood handling residue, waste wood, banana and pineapple plant residue, bamboo processing residue and waste bamboo were reasonably assessed in this study.
