Risk analysis of forest fires in China based on information diffusion theory

Abstract

Forest fire is an important influencing factor in the forest ecosystem, which has an important influence on the stability and balance of the ecosystem. It is of great significance to study the risk of forest fire to improve the management ability and countermeasures of forest resources risk as well as forest resources protection. The study collected data on the number of forest fires in China from 1990 to 2020 and analysed the risk of forest fires in China using the method of information diffusion theory, and the protection of forest resources is discussed. The study points out that the number of forest fires and the area of forest damage are generally decreasing, all these are closely related to the protection of resources and the construction of ecological civilization and the relatively perfect monitoring system of resources and environment etc. in China. The study results show that China has one general and large forest fire every 3.08 years, a major forest fire occurs in more than 10 years, a huge forest fire occurs in about 7 years, and a general and larger forest fire is in about 5 years. The study mainly provides reference for the forest risk management and resources protection and puts forward some policy suggestions for disaster prevention and control in China, especially in the protection of forest resources, there should be a clear technical and economic policy for forest disaster management and control, and a clear path for the formulation of technical and economic policy for it in China, so as to promote the development of environmental protection.
