Abstract


Protection of the forest is the personal responsibility of each of us to achieve the harmony of man and nature. Forest fire not only burned a lot of forest resources, destruction of the natural environment and ecological balance, and a direct impact on the industrial and agricultural production, and a serious threat to the safety of life and property of the people. How scientific methods of forest fire prevention resources the configuration tuning planning, give full play to the role of fire resources is an important component of forest areas for sustainable development. In this paper, the overview of domestic and international forest fires and forest fire prevention resources in the research situation at home and abroad, the use of the forest fire information system in Guangzhou types of information. In-depth research of Guangzhou City, socio-economic, physical geography and forest resources in the current situation, the use of geographic information systems, computer technology, and knowledge of graph theory and mathematical methods, the following aspects of the study of Guangzhou City, the forest floor fire resources. Forest fire space distribution with roads, rivers, settlements, species, age, elevation, slope and aspect, to draw forest fires spatial distribution of, and established on the basis of the forest fire danger index model to determine the fire risk zone level with the rules, the forest fire risk zone map forest fire risk zoning map, to provide data to support research for other fire prevention resources. The proposed Lookout mesh network site and implementations. Factor affecting the lookout net outlets location and weight, the impact of factors including: the viewshed area, traffic conditions, around the fire danger rating, water conditions, economic conditions. Using GIS software visual domain analysis and visualization area, combined with the the fuzzy mathematical knowledge of the impact factor nearness calculated to determine the lookout network settings. Lindau density of the study area were analyzed and the existing forest road network density can not meet the requirements of forest fire prevention. The study appears Biological Fuelbreak construction level below the State Forestry Administration to develop planning standards, and the the existing Biological Fuelbreak construction on the basis of a program for planning and design. Proposed a regulation to achieve method of fire suppression resources. Regulation, water and fire suppression team site analysis, study of forest area water water Lindau connectivity, while analysis of the relationship between fire suppression team sites, water sources and different forest fire danger rating area for different fire danger rating the area, based on traffic conditions, terrain conditions, setting the best fire suppression team site location, the shortest path to choose, calculated from the site of fire suppression team to reach the water Lindau eventually reach the time of each fire danger area meets the forest fire requirements.
