Through standard plot investigation and method of trunk analysis, systematic research is conducted on storage and productivity of the planted forest and their relationship with site condition. As shown in the research, productivity of planted forest of Larix kaempferi in low latitude area is higher than that in high latitude area while stand productivity is higher in slight acid soil. Contents of potassium element in the soil have Considerable influence on productivity of the Larix kaempferi forest.展开更多

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
