The changes in forest resources have a direct bearing on environmental quality. The paper gives a detailed account of the dynamic change in forest resources in China, including the overall process of forest evolution, the status quo and features of the existing forest resources and the development and use of major forest resources. In addition, it analyses the current situation of China's environment and explores the main contributing factors based on the overall environmental situation. In order to achieve sustainable management of forest resources and improve the environment in China, the Chinese government attaches great importance to the protection and development of forest resources as well as environmental development and improvement. The paper gives an overview of the thinking for sustainable forest resource and environmental development in the future and current focus of efforts.展开更多

Results indicated that the 6 environmental factors underinvestigation had effects, to various extents, on growth of the young trees. Based on the findings, suitablegrowing conditions for regenerated young tree of Pinus Koraiensis under forest were identified andcorresponding silvicultural measures were proposed for operational practice.展开更多
