Abstract: China is in a critical period for the ownership reform of state-owned and collectively owned forests, which desiderates theoretical support and practical experience. However, the researches on the management modes of these forests and their ecological effects are scarce. In Europe and America, manifold ownership forest management has a long history, and relevant experts have made many researches on the ownership management contents and modes, as well as their effects on forest timber productivity, biodiversity, and landscape feature. To summarize and refer to these research harvests is definitely necessary and imminence for our forest ownership reform. This paper reviewed the management aims, modes, and ecological effects of state-owned and privately owned (industrial private and non-industrial private) forests, the parcelization and divestiture of forest ownership, and the associated protection policies of different ownership forests in the representative countries and regions in Europe and North America. The research prospect was also put forward.
