摘　　要：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。The paper described the annual occurrence of forest fires in China from 2000 to 2012, and analyzed the spatial and temporal distribution of summer forest fires. The number of forest fires inter-annually remained stable between 2000 and 2012, stayed high in 2003 - 2005, and reached the highest peak in 2008, while the number went downward in recent years. The number of summer forest fires remained at a high level between 2003 and 2007, especially high in 2003 and 2006, while dropping down in recent five years. More frequent forest fires occurred in summer in Central and Southwestern China, while major and extra large forest fires erupted the most in northeast area of China. The summer forest fires occurred in China is characterized with high level, heavy destruction, large fire area and large affected forest area.
