Broad-leaved evergreen forest is a zonal vegetation type and an important part of land ecosystems in subtropics of the world. In the past decades, Chinese botanists and ecologists have made great progresses in study of flora, species composition, physiognomy, structure, dynamics and functions of broad-leaved evergreen forest. Abundant data has been collected and a great number of papers have been published. At the same time, some demonstrative regions of broad-leaved evergreen forests with their own special regional features were established in Junyunshan Mountain (Sichuan Province), Tiantongshan Mountain (Zhejiang Province), Dinghushan Mountain and Heshiding Mountain (Guangdong Province), Ailaoshan Mountain (Yunnan Province), Wuyishan Mountain (Fujian Province). In the studies of succession, research has been coverd successive processes, community composition, structure dynamics, and successive models, and further studies were gradually focusing on ecosystem functions. However, studies of main population dynamics and physi-ecology in broad-leaved evergreen forest were still poor. In the studies of regeneration dynamics of broad-leaved evergreen forest, Chinese ecologists have made big progresses in time and spatial dynamics of seed rain, seed band, seed sprouting, young tree growth, forest gap and its roles in forest dynamics. Further more, mechanisms of broad-leaved evergreen forest succession were explained by studying physi-ecological characteristics of dominant species. In the studies of restoration and reconstruction of the forest, characteristics and restoration processes of some degraded broad-leaved evergreen forest ecosystems were investigated, and these theory and technologies were used to direct the practices of the forest restoration and reconstruction. Based on the above results, the forest dynamics in succession, regeneration, degeneration and restoration of broad-leaved evergreen forest were summerized in this paper. An outlook has been given according to domestic and international research trends, including integration of remote sensing, geographical information system and global position system, studies of forest dynamics, and degraded physi-ecological mechanisms, origins and phylogeny, forest protection and restoration ecology, physi-ecology and population biology of critical species, functional eco-service, sustainable development and impacts of global change on broad-leaved evergreen forest ecosystems.
