摘要:
能源林主要是生产热能，树（草）种燃烧值的高低，是评选能源林树（草）种的重要指标。通过对黄土高原29种树（草）种燃烧值的测定表明，木本植物的燃烧值大于草本植物，这种能量差异主要是草本植物含有较多的灰分，结构物质纤维素含量较高，木本植物灰分含量较低，脂类物质相对较多。同时发现10种树种的热值随着年龄的变化多以5年生时的热值为最高，这对确定树种的平茬期，在生产上具有重要意义。
Abstract:
A energy forest is principally used as producing heat energy, and a tree species’s caloric value (grass included) is a significant index to choose energy-forest species (grass included) through appraisal. By the determination of caloric value for twenty-nine tree species (grass included) in the loess plateau, it showed that a woody plant’s caloric valne was higher than a grassland plant’s, the energy difference between woody and grassland plants was chiefly due to more ash content and higher cellulose content of a grassland plant, while lower ash content and more fatty substance of a woody plants. Meanwhile it was found that the caloric values of ten tree species varied with its age, with the highest caloric value of a tree species at the age of five, this finding is significant for determining mowing stage of a tree species in the production.
