Abstract: The largest area of subtropical evergreen broad - leaved forests distributed naturally in southern and southwestern China play an important role in biological diversity and natural environment conservation.However, human - induced disturbances in the last several decades have destroyed most of the valued vege-tation. Diversity loss and environmental degradation have been a serious problem. It has been pressing and difficult work to restore and rehabilitate the evergreen broad - leaved forests. In China, although numerous studies dealing with the artificial rehabilitation have been carried out, the effect on conservation and restora-tion of biological diversity has been found to be ineffective due to restricted tree selection. Few studies have undertaken natural regeneration and floristic diversity restoration.

摘要： 对瓦屋山的湿性常绿阔叶林破坏后自然恢复的次生群落 及其与原生湿性常绿阔叶林的比较研究表明，中山湿性常绿阔叶林砍伐破坏后在封山条件下 经过42年的自然恢复形成的植被，已经形成常绿阔叶外貌，其物种多样性丰富，区系组成已 经与破坏前相似；湿性常绿阔叶林的典型珍稀濒危和标志种已经随森林环境的恢复而迅速回 归或就地保存；虽然自然恢复的次生林乔木层尚存在较多落叶伴生种，但优势种已与破坏前 相似。有力地说明了中山湿性常绿阔叶林砍伐破坏后物种自然恢复迅速、恢复效果也较好， 暗示自然恢复是该区常绿阔叶林及其生物多样性恢复和重建的有效途径之一，而物种多样性 的恢复可作为生态恢复效果评价的有效指标之一。
