Abstract—The ownership of property of collective owned forest in eastern Liaoning Province, China, has been transformed from collectivity owned to farmers owned, and the transfer has brought many different woodland management methods. Planting ginseng is the main management method which was developed before the transfer and will be more popular in the future. Floristic surveys were performed in 4 different forests under different planting methods for ginseng in Fushun City which is the main ginseng planting area of eastern Liaoning Province, China, to assess the impact of planting ginseng on understory vegetation species diversity. This impact was evaluated through analyzing species richness, species evenness and species diversity. The purposes of this study were to test (1)have there been changes for understory vegetation species diversity in the areas with planting ginseng?(2)do different planting methods take different changes to understory vegetation species diversity, and (3) which method will be suitable for the development of forests in eastern Liaoning province? Our results showed that ginseng planting had greatly destroyed the shrubbery and reduced the species richness of herbage in all sites. In terms of species evenness, we only found a decreasing for index J in Larch forest with MM and increasing for all other sites. This study also expressed that the species diversity of understory herbaceous vegetation was changed differently among different sites. Our finding suggests that planting ginseng in broad-leaf mixed forest with the NG method which means the ginseng will be in natural growth without human management after seeding is the best choice for the development of forest and economical profit of farmers.
