摘　　要：在人类活动对生态系统的影响十分强烈的当今 ,生态系统的非平衡性正引起越来越多生态学家的注意 ,已逐渐成为生态学研究中的重要观点之一。本文简要介绍了亚高山针叶林生态系统的基本概况。在此基础上 ,将目前生态学研究中的非平衡理论与亚高山退化针叶林生态系统相结合 ,探讨了亚高山针叶林生态系统中不同结构水平所存在的非平衡性问题 ,以及该领域的研究趋势 ,旨在推动我国退化森林生态系统非平衡性研究工作的深入开展。Non-equilibrium of ecological system is a very important view and refers to disturbance, heterogeneity, scale and dynamics. At recent, it had been considered as a scientific paradigm in ecology. In this paper, Subalpine conifer forest ecological system was brief introduced, and their non-equilibrium problems were discussed at the level of population, community and ecological system. Finally, ecological perspective of non-equilibrium of subalpine conifer forest was introduced and the author s opinions were g...
