为了研究中国地区生物质燃烧不同阶段释放的各种痕量气体排放比与排放因子，建立了动态与静态燃烧室以及ＣＨ４、ＣＯＳ、ＣＯ、及ＣＯ２的采样、富集、分析方法；然后对典型乔木、灌木与草的地上部分生物质进行规模不同的燃烧实验，测得痕量气体的排放比和排放因子．根据全国森林生态系统碳贮量的估计及火灾统计资料，初步测算了中国地区生物质向大气中释放含碳痕量气体量．
In order to study the emission and emission factors of various trace gases released in different stages of biomass combustion in China, the methods of sampling, enrichment and analysis of dynamic and static combustion chambers and CH4, COS, CO and CO2 were established. Then, Trees, shrubs and grass aboveground biomass were subjected to various scale combustion experiments and the emission and emission factors of trace gases were measured. Based on the national estimates of carbon storage in forest ecosystems and fire statistics, preliminary estimates of the amount of carbon-bearing trace gases released into the atmosphere from biomass in China were made.
