摘　　要：回顾总结了芒萁种群特性、芒萁单优层片的发育及其生态效应的研究成果,并探讨亚热带低山丘陵区森林植被恢复的关键问题和生态对策。基于该地区芒萁层片与森林群落乔木层片的生态关系,分析了芒萁层片发育的条件、生态后果和对阔叶树种子发芽、幼苗生长两个关键环节的抑制作用,认为芒萁的化感效应也是1个值得研究的重要问题,指出健康森林生态系统各级层片具有生态依赖性而不是排斥性。对今后有关植被退化与恢复尚待研究的问题进行了探讨,如芒萁层片发育与森林群落结构的关系、芒萁化感作用机理、芒萁的繁殖对策。The research results on the characteristics of Dicranopteris dichotoma population,D.dichotoma monodominant synusium and its ecological effects are reviewed,and the key question and ecological strategies for forest vegetation restoration are probed into in the hilly area of Subtropical region,Zhejiang province.According to the ecological relationships between D.dichotoma synusium and arbor synusium of forest community,the development conditions of D.dichotoma synusium,its ecological effects including the inhibition on the seed germination,seedling growth of broadleaf trees are analyzed.It is very important to study the allelopathy effects of D.dichotoma in the future.The synusiums should have ecological interdependent rather than repel each other for healthy forest ecosywtem.Some problems of the vegetation degradation and restoration should be settled in the future study,such as the relationship between the development of D.dichotoma synusium and the structure of the forest community,allelopathy mechanisms and reproductive strategies of D.dichotoma.
