Abstract: Shenyang Arboretum, Chinese Academy of Sciences was established 1955, and located in the business and cultural center of Shenyang. It has introduced 546 woody plant species in Northeastern China, which belong to 118 genus and 51 families. With natural regeneration, it has become a multi-generation and multi-stratum near natural-forest community. Based on plant community ecology, this paper studied the species composition and floristic characteristics, life type and stratum structure, vertical structure and stratification, horizontal structure and mosaic, natural regeneration and development, and the habitation and conservation of wild lives. The forest community in this Arboretum is a typical near natural urban forest in Northeastern China.
