Abstract:

In order to clarify each factor influencing China’s forest health condition, the author firstly analyzed the connotation of forest health and concluded that the ideal healthy forests were those that had certain resistance and could normally grow without being threatened by factors such as forest fire, harmful organisms (plants, pestilence, insect pests, and so on), meteorological disasters, air pollution and deforestation. Meanwhile, the function or value of forest including underground water, recreation location, wild animal protection, wood supply and self-updating would not be affected. It then analyzed all factors influencing China’s forest health and illustrated all the urgent problems confronting research on forest health risks. Finally it envisioned the research on China’s forest health from the aspects of forest health risk indicator system establishment, evaluation of each forest health risk indicator’s influence on forest damage or losses, regulation of insurance rate of each forest health risk indicator, forest category, forest structure, forest industry structure adjustment and forest health management policy. It was believed that this research was significant for the sustainable development of forest health and could provide efficient methods for management of future forest resources.
