生物产量的研究,是研究森林生态系统的核心。六十年代以来,欧美、日本、苏联对森林生物产量的研究,达到了相当活跃的程度,我国从七十年代末开始研究。但仅限于杉木、黄山松、油松、樟子松、红松等人工幼中林。天然林的研究较少,如长白山阔叶红松林、内蒙古的白杄、青海云杉和油松林等研究也只是近几年才开始的。1982年我们在根河林业局研究了大兴安岭林区兴安落叶松原始林中分布最广的三种林型成熟林的生物产量。
The study of biomass production is the core of studying forest ecosystem. Since the 1960s, Europe, the United States, Japan and the Soviet Union have reached quite active levels in the study of forest biological production. Since the late 1970s China began to study it. But only in Chinese fir, Pinus taiwanensis, Pinus tabulaeformis, Pinus sylvestris, Pinus koraiensis and other artificial young trees. There are few researches on natural forests, such as the broad-leaved Korean pine forest in Changbai Mountain, the Betula platyphylla in Inner Mongolia, the Picea crassifolia and Pinus tabulaeformis in Inner Mongolia. In 1982, we studied the biological yield of the three mature forest types of Larix gmelinii forest in Daxing’an Mountains.
