摘要: 次生林是中国森林的主体,在结构组成、林木生长、生产力、林分环境等诸多方面与原始林和人工林有着显著的不同.因此,经营好次生林对中国天然林保护等林业工程实施及国家生态安全建设具有重大意义.本文在广泛收集国内外有关次生林研究结果的基础上,探讨了次生林经营领域中基础研究所涉内容,揭示出次生林经营研究中所关注的基础问题,提出了次生林经营基础研究的主要内容与方向,对今后次生林经营研究和中国天然林保护等林业工程建设具有参考价值.

Abstract: Secondary forest is also called as natural secondary forest,which regenerates on native forest that has been disturbed by severe natural or anthropogenic disturbances.The structural and dynamic organizations,growth,productivity and stand environment of secondary forests are significantly different from those of natural and artificial forests. Such significant differences make secondary forests have their own special characteristics in forestry. Secondary forests are the main body of forests in China. Therefore,their management plays a very important role in the projects of natural forest conservation and the construction of ecological environment in China or in the world. Based on a wide range of literature collection on secondary forest research,the fundamental studies of secondary forest management were discussed. The major topics are as follows: 1) basic characteristics of secondary forest,2) principles of secondary forest management,3) types of secondary forest,4) community structure and succession dynamics of secondary forest,including niches,biodiversity,succession and so on,5) main ecological processes of secondary forest,including regeneration,forest soil and forest environment. Additionally,the research needs and tendency related to secondary forest in the future were also given,based on the analyses of the main results and the problems in current management of secondary forest. The review may be helpful to the research of secondary forest management,and to the projects of natural forest conservation in China.
