摘    要:在对花曲柳、蒙古栎、核桃楸等天然次生林和落叶松人工林的天然更新状况、林下枯落物状况和土壤种子库状况进行调查的基础上,对4种林型枯落物与天然更新的相关性进行分析的结果表明,枯落物对次生林的天然更新有一定的障碍作用,枯落物过多,有效更新幼苗数量就会减少,有效更新状况与枯落物的数量呈负相关性.

关 键 词:枯落物  天然更新  相关性

Abstract:According to the investigation of natural regeneration,litter and soil seeds bank the of natural secondary forest formed by broad-leaves trees(Fraxinus rhynchophulla Hance,Quercus mongolica and Juglans mandshurica) and larch plantation in Dasuhe forest farm in Qingyuan county of Liaoning Province.The correlation between the litter and natural regeneration of secondary forest which was composed of Fraxinus rhynchophulla Hance,Quercus mongolica,Juglans mandshurica and larix olgensis separately was analyzed in this paper.The statistical analyses showed that the litter acted a barrier effect on the natural regeneration of secondary forest.The thicker of the litter was the fewer of the regeneration seedlings.There was a negative relationship between the forest litter and the natural regeneration.
Keywords:Litter  Natural regeneration  Correlation
