摘 要:
草地空斑（gap）为种苗建植提供了适合的微生境，对种苗建植起着重要作用。介绍了种苗建植和空斑的概念及空斑的功能分类，从空斑对种子萌发、种苗出苗和存活的影响等方面，概述了草地空斑对种苗建植的影响，提出了今后研究的建议，为开展草地空斑和种苗建植研究提供参考。[著者文摘]

Abstract:
Grassland gaps provide ＂safe sites＂ for seedling establishment. Many plant species need gaps for successful germination, emergence and establishment. Grassland gaps play an important role in promoting seedling recruitment. This paper reviewed the concept of seedling establishment and gap, the response of different species to different types of gap and given some suggestions on further research work. It may help to conduct the research work in this field.[著者文摘]
