亚热带常绿阔叶林植被恢复研究进展

Review of reserches in restoration of subtropical evergreen broad-leaved forests

回顾了在具有影响的几种演替理论指导下的亚热带常绿阔叶林恢复研究的主要内容 ,包括群落结构研究 :群落的发育、波动、更新和演替 ;种群的特征、结构和竞争压力以及物种的生理生态学特征在群落进展演替中的变化。土壤动态变化研究 :土壤的理化性质、肥力、有机质含量在与群落协同发展过程中的变化。植被恢复研究方法 :数学模型在时间序列和生态序列研究方法中的应用。建议在以后的研究中应增设固定样地 ,加强定位研究以及加强群落演替过程中树种遗传机理方面的探索 ,优化次生演替数学模型等。参

The zoned vegetation in subtropics is evergreen broadleaved forest.Because of human disturbance,most areas are now covered with secondary forest.The study of the theories,communities,and soil were reviewed in this paper,including ①physiological change of the species during succession,②the change of population characteristic,structure and pressure and effects of competition on dynamic process,③the formation,fluctuation,regeneration and succession of the community,④the development of the soil quality,fertility,and organic matter during succession,⑤the use of the secondary succession model.Some new ideas for vegetation restoration studies are suggested,such as increase the study of the permanent sample plots,further explore for the hereditary character of the species,optimizing the succession models
