摘　　要：异龄林生长动态是林分生长和收获预估模型体系的主要组成部分,更是树种组成优化、择伐周期优化、林分直径分布优化及最优蓄积生长量等经营决策中一个不可缺少的部分。综述了国内外近年来异龄林生长动态研究,主要包括直径分布、生长模型和经营方式等方面进展,讨论了异龄林生长研究的发展趋势。The growth model of uneven-aged forest is a main component of stand growth and yield prediction model system. Meanwhile, uneven-aged forest growth dynamic model is an indispensable part of manage- ment decision which is the optimization of species composition, cutting cycle, diameter distribution and volume growth. In recent years, the diameter distribution, growth model, management mode were the main research contents of the growth dynamics of uneven-aged forest. Studies of those aspects all over the world were summarized. The developing trends for the future in the studies of the effects on uneven-aged forest growth were presented.
