摘要
由于非再生能源资源量有限,生物质能的开发和利用就具有越来越重要的意义.该文通过对中国能源林树种的单位面积生物量与产单位标煤热值生物量所需土地的面积及生产木质燃料所需成本三者之间的关系进行分析,在三者之间建立数学模型;并通过时间序列方法预测未来煤炭的价格,将各能源林树种生产木质燃料的成本与煤炭价格进行比较分析,最终确定目前可以利用哪些能源树种生产成型木质燃料来替代煤炭,从数量上提供可行的依据.
As the amount of energy is becoming scarce, it is more important to exploit and use bio-energy. In this article, some models had been built through analyzing the inter-relationship among biomass per m^2, area of biomass having standard coal equivalent（SCE） and cost of producing woody fuel. Then, by the time series analysis method, we estimated the coal future price and compared it with woody fuel cost of partial energy trees. In conclusion, some kinds of trees were ascertained to replace the coal as fuel presently and the feasible bases were provided quantitatively.
