摘　　要：沙地樟子松是我国北方地区广泛引种的主要固沙造林树种,但在引种地只有少数地区能够完成自然更新过程。本文从沙地樟子松落种特征、土壤种子库、种子扩散、种子萌发、更新苗特征、天然更新类型以及影响天然更新因素等方面综述了沙地樟子松天然更新研究现状,并探讨其天然更新的关键影响因素,同时提出了研究展望。As a main sand-fixing tree species widely introduced in northern China,Pinus sylvestris var. mongolica can complete the natural regeneration process in a minor part of introducing region. In this paper,research status of natural regeneration of Pinus sylvestris var. mongolica in sandy land has been summarized on these aspects,such as character of falling seed,soil seed bank,seed diffusion,seed germination,character of seedling,natural regeneration types and the factors affecting natural regeneration. Meanwhile,the key factors influencing natural regeneration have been discussed,and the research prospects have been put forward.
