文中介绍了我国2000—2012年森林火灾发生的整体情况,分析了我国夏季森林火灾的时空分布规律。2000一2012年我国森林火灾发生次数年际间大体保持平稳,2003—2005年达到一个较高的峰值,2008年达到最高峰,近几年来则呈下降趋势。夏季森林火灾的发生次数在2000—2007年处于较高水平,尤其是2003年和2006年火灾发生次数最多,而近5年来则处于较低水平并有下降的趋势。我国华中地区和西南地区发生夏季森林火灾次数最多,而东北地区重、特大森林火灾发生最多。我国夏季森林火灾具有等级高、破坏性大、火场面积和受害森林面积较大等特点。
This paper describes the overall situation of forest fires in China from 2000 to 2012, and analyzes the spatial and temporal distribution of summer forest fires in China. Between 2000 and 2012, the number of forest fires in our country remained generally stable from year to year, reaching a relatively high peak in 2003-2005, reaching a peak in 2008 and declining in recent years. The number of summer forest fires was at a high level from 2000 to 2007, especially in 2003 and 2006, with the highest number of fires in recent years and the lowest level in recent 5 years with a declining trend. China has the highest number of summer forest fires in Central China and Southwest China, while heavy and super-large forest fires in Northeast China have the most occurrences. China’s summer forest fire has the characteristics of high grade, destructiveness, large fire area and large area of affected forest.
