摘要： 冷杉林每年凋落物量(干重)0.5—4.0吨／公顷，枯枝落叶层(Ao层)干重总量每公顷40吨左右。本文通过观测和实验，探讨了冷杉林Ao层物质循环格式及其在生态系统中的养分和水分循环的特殊重要作用，以及对群落中的植物分布、生长发育的影响。

Abstract: It is found that the annual fall of fir forest in dry weight ranged from 0.5 to 4.0 ton/ha and total mass of forest floor in dry weight averaged about 40 ton/ha. After observation and various experiments, the pattern of mineral cycle of forest floor, the role of forest floor in ecosystems mineral and water transformation, and the effects of floor layer on distribution, growth and development of forest plants are discussed.
