摘要: 对内蒙古大兴安岭成熟兴安落叶松纯林的3种不同采伐林分类型(原始林、渐伐林、皆伐林)的土壤种子 库储量、质量及其垂直分布(枯枝落叶层、土层0~5cm和5 ~10cm)进行了研究,结果表明:不同的采伐林分 生长状况,决定了不同的土壤种子储量,渐伐林种子储量最多,皆伐林种子储量最小;从种子库活力程度看, 种子整体质量非常差,完整种子中大部分为空粒种子,各林分均为70%左右;土壤种子库中种子集中分布在枯 枝落叶层中;各林分林下均有幼苗,表明兴安落叶松纯林土壤种子库种子具有一定的萌发能力。

Abstract: The density ,qualit and verica dstrbuin liter layer ,soil layer 0~5 cm and 5~10 cm)of soil seed bank of13 dfefe cuting type( virgin fores sucesisie cuting forest .dler-eutin foresls )on maturation of Larix gmelini pure forest in Da Hign Moumtains were inestigaued. The resuls showed that cuting forest growuh slatus detemines soil seed densties,scesse cuting forest had the largest seed reserves and clear-cuting forest was minimum; the seed qualities were low and almost 70% seeds were emply in each sland ;soil seeds concentrale distrbution in liter layer, and each stand both had undersory seedings which indicated that the soil seed bank of Larix gmelini pure forest had certain potential of germination.

Key words: Larix gmelini, soil seed bank, distribution pattern, seed vitality
