摘　　要：CWD是特别重要的扎根介质,可以作为种子萌发、幼苗生长和发育的生长基质,能起到保育苗木的作用,且森林中树木倒伏形成的CWD及林窗对种子的传播具有重要作用.本文结合对CWD的基本功能研究,概括了新近有关CWD对森林植物种群更新方面的功能研究进展.同时,指出了未来CWD研究的重点方向应该是加强CWD生态功能的机理性以及更新幼苗存活的持续性研究,并从多维度开展CWD作用的系统性研究.CWDis a particularly important rooting medium,which can be used as a growth substrate for seed germination,seedling growth and development,and can play a role in protecting seedlings.CWD and gap formed by lodging trees in the forest play an important role in seed spread.In this paper,based on the basic function research of CWD,the recent research progress on the function of CWD in forest plant population regeneration is summarized.At the same time,it is pointed out that the key direction of CWD research in the future should be to strengthen the mechanism of CWD ecological function and renew the sustainability of seedling survival,and to carry out systematic research on CWD function from multiple dimensions.
