对我国的有机废弃物（包括作物秸秆、林业剩余物、畜禽粪便、林业采伐及加工剩余物、育林剩余物、工业有机废弃物和城市有机垃圾）及可用于生物质原料植物生产的边际性土地（包括宜垦和宜林的荒地、现有的能源林地与农地）的相关资料进行了系统收集、整理与分析，分别提出了它们的资源量及可经济收集量。按2007年生物质产出现状与潜力，中国生物质资源的年产能为9.32亿tce，其中有机废弃物和边际性土地分别占41.1 %和58.9 %；预测2030年生物质原料资源的年产能为11.71亿tce，其中有机废弃物与边际性土地分别占48.3 %和51.7 %。

The data of organic wastes (including residues of crops and forests, animal excretion, agricultural and forestry processing, industrial wastes and municipal organic wastes) and marginal land (including suitable forestland, reclaimable wasteland, existed woodland and arable land) that suited to produce plants were systematically collected, sorted out and analyzed. The corresponding resource volume and available volume for economical harvesting were also put forward. According to the situation and potentiality of biomass products in 2007, it was concluded that the total productivity of China's biomass feedstock in a year equals to 932 million tce, with organic wastes and marginal land accounting for 41.1 % and 58.9 %, respectively. It was projected that to 2030, the annual potentials of biomass feedstock will be increased to 1 171 million tce, and the share of organic wastes and marginal land will be 48.3 % and 51.7 %,respectively.
