人类对周围环境影响的急剧增长,促进了生态系统学科的迅速发展。做为研究不同生态系统能量和物质交换的基础,生物量的研究也得到高度重视。从50年代开始,特别是国际“人与生物圈”研究计划的执行,世界上许多国家对森林生物量开展了广泛的研究。近年来,我国的林业科学工作者也相继在黑龙江、吉林、贵州等林区进行了研究。这些研究促使森林生物量的测定方法不断进步,并取得了各地区主要树种森 The dramatic increase of human impact on the surrounding environment has promoted the rapid development of ecosystem disciplines. As a basis for studying energy and material exchange in different ecosystems, the study of biomass has also received great attention. Since the 1950s, and especially the implementation of the international “Man and the Biosphere” research program, many countries in the world have conducted extensive research on forest biomass. In recent years, China’s forestry scientists have also conducted research in Heilongjiang, Jilin, Guizhou and other forest areas. These studies led to the determination of forest biomass methods continue to progress, and has made the main species of forest in various regions
