Cost-benefit Analysis Of The Forest Fire Early Warning Model

Since the eighteen of the Chinese Communist Party put forward the construction of ecological civilization, The ecological problem more and more get the attention of the society,So maintenance of forest resources become the most critical step in the construction of ecological civilization. Protection of forest resources is the rational utilization of forest resources,and Reduce or even prevent forest fires, and Deforestation and other acts of destruction of forest resources, thus exacerbating the deterioration of ecological environment. Due to forest fires uncertainty, great harm. So how to prevent forest fire becomes an urgent problem to be solved.Forest fire warning engineering is a complicated system engineering, is a scientific and technical work in the fight against natural disasters.In this system, the establishment of an efficient and robust forest fire early warning model has become an important basis for the prevention and control of forest fires. Each has been established and practical application of forest fire warning model has its own rationality, but each model construction need cost and can bring benefit as an important basis of our choice. The input and benefit analysis of the specific model has become the focus of the world. Although our country starts late in terms of construction of forest fire early warning model. However, the scholars have established the forest fire warning model in line with the characteristics of the forest region in China. Research also gradually transferred to the construction of forest fire warning model in the process of the research on the costs and benefits. Now the forest fire early warning model of how to choose a highly efficient still become the focus of each scholar research in China.From the point of view of optimizing the investment and to maximize the benefits, first of all, from the domestic and foreign background information analysis, this paper discusses the shortcomings of our country forest fire warning, and gives the research direction and the thinking direction. Secondly, from the aspects such as personnel, equipment and technology to measure the cost of forest fire warning work, and from the forest fire caused direct economic losses,indirect economic loss and ecological economic loss to divide the assessment breakdown, and expounds the corresponding detail calculation method. To evaluate the benefits of forest fire warning model laid the foundation. Finally, through the comparison of the data of Guangzhou city forest fire early warning model and comprehensive fire early warning model, and then puts forward the improvement suggestion to the early warning model. Provide decision support for the planning and construction of efficient and stable forest fire warning systems in our country. This paper focus on the use of cost benefit method combined with Guangzhou in 2005 and 2006 the forest fire data to analysis of Guangzhou City, the forest fire early warning model obtained benefit, it is concluded that the Guangzhou city with great benefits brought by multi-factorprediction model. At the same time, the integrated Fire Wire index model of high prediction accuracy of the effectiveness of combined with the data of the city of Guangzhou. Finally put forward perfect forest fire early warning model more in line with the needs of the construction of ecological civilization in China, worthy of the forestry sector to increase model of investment.After optimization model bring benefits far beyond the model construction of a one-time cost of inputs and later maintenance cost, the research for the forestry sector to further improve the forest fire early warning model provides an important reference.
