Applying Canadian Forest Fire Weather Index System in Tonghua City
摘要
Abstract
According to the characteristics of forest fires in Tonghua City,we introduced the Canadian forest fire weather index system.We studied the correlation of fire weather indexes and forest fire,and division of forest fire danger rating with the forest fire data and the meteorological data of 1996—2010 in Tonghua City.The results indicate that number of forest fires and other forest fire weather indexes are highly significant in addition to Drought Code;forest area burnt, area burnt and Fire Weather Index, Initial Spread Index are also highly significant;forest area burnt, area burnt and Fine Fuel Moisture Code aren't highly significant, but the significances are very close to 0.01,so Canadian forest fire weather index system is suitable for Tonghua City.We divided forest fire danger ratings on the premise that extreme days should be less than 3% of the total study period and the geometric method.Forest fire frequency,area burnt ratio and forest area burnt ratio are the largest under level 4 of fire weather.Forest fire is similar to normal distribution,so the hierarchy method is suitable for Tonghua City,but further examination and comparison are required to make the system for forest fire forecast in Tonghua City.关键词
