Abstract

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
