摘　　要：总结了限制人工林林下植被恢复的包括种子归所(如动物取食、搬运,种子储藏环境,土壤病害,化感作用等)、土壤肥力、枯枝落叶层的厚度、林分密度等因素,并在分析各因素的基础上提出了一些如间伐、营造混交林、科学经营、去除地被物等行之有效的防治措施。Factors affecting understorey vegetation restoration were summarized including seed fate （ herbivore foraging and moving, seed storage environment, soil disease, allelopathy and so on）, soil fertility, thickness of litter and forest density. Based on analyzing of these factors, some effective restoration measures such as thinning, constructing mixed forest, scientific management, litter cleaning were put forward and hoped to be used in practice.
