中国林木生物质能源潜力测算及变化趋势

基于各省份林业统计数据，文中利用自下而上分析方法测算了中国林木生物质能源的资源潜力，并对变化趋势进行分析。结果表明:1993—2013年中国林木生物质能源资源潜力由0.78亿t标准煤增长到1.05亿t标准煤，20年间增长了34.62%；从资源构成来看，灌木平茬剩余物和采伐剩余物是林木生物质能源的主要供给来源；从区域变化来看，不同省份资源潜力呈现明显差异，但全国平均水平的逐步提高并非个别省份资源潜力大幅度提高使然，而是绝大部分省份资源潜力的共同增长促成了平均水平的连年提高。

A Study of the Potential Estimation and Changing Trends of Woody Biomass Energy Resources in China

Based on the provincial forestry statistical data, this paper calculated the woody biomass energy resource potential in China by using the bottom-up method and analyzed the changing trend. The results showed that the woody biomass energy resource potential increased from 0.078 billion tons by standard coal in 1993 to 0.105 billion tons by standard coal in 2013, 34.62% up during the 20 years. Moreover, the shrub stubble residues and forest harvesting residues were the main sources of woody biomass energy resources. Although the total resource potential of various provinces in China presented an obvious difference, the gradual increase of national average woody biomass energy potential was not the result of the large increase in a few provinces but the common increase in most provinces.
