Research progress on forest gaps and regeneration of natural forest.
The forest gaps play an important role in the process of natural regeneration of the forest. In addition, it also have a vital part in community composition, functional structure, material circulation, energy flow and biodiversity conservation, which is the driving force of community succession. In this paper, we summarized the hot topics of forest gap regeneration and seed germination, species diversity and biological invasion. In order to provide reference for understanding forest natural regeneration and sustainable management, this paper focused on the systematic connection between natural renewal and habitat elements, the large-scale forest disturbance, the diversity of the forest ecosystem and the social service functions, the response mechanism of the biological invasion, the initiation and renewal of the forest plant community, and the influence of interlayer plants on the forest gaps.
