摘要:

从森林可燃物载量调查工作的复杂性、专业性等角度出发,选用植被区域、树种(组)、森林起源、龄组、郁闭度等级等5项指标,设计了全国和省域尺度森林可燃物载量样地调查的分层抽样技术体系。在每个样地内,对乔木层可燃物载量,采用每木调查数据结合异速生物量模型或生物量扩展因子方法进行估计,并通过样方调查和样品含水率对灌木层、草本层、枯落物层和腐殖质层进行联合估计。该方法对科学指导全国或区域尺度森林可燃物载量调查与估算具有重要指导和借鉴意义。

Abstract:

From the viewpoint of tediousness and professionalism of forest fuel load investigation,a stratified sampling system for the plot survey of forest fuel loads at national and provincial scale were developed based on five commonly used indicators,namely vegetation area,tree species,stand origin,age group and canopy density.Within each specific plot,the fuel loads of tree-layer can be estimated by using the data of individual tree survey combined with the algometric biomass model or the biomass expansion factor,while fuel loads of shrub-,herb-,litter- and humus-layer should be jointly estimated by the quadrat survey and the data of sample moisture content.This method has important guidance and reference significance for the survey and estimation of forest fuel loads at national or regional scale.

Key words: forest fuel, plot survey, estimation model, stratified sampling, fuel load
