摘 要:通过对2000~2004年黑龙江省夏季森林火灾进行研究分析发现,该地区夏季林火呈现明显的空间、时间分布特点。(1)黑龙江省夏季林火只在121°12’~130°16’E和46°53’~53°25’N之间发生过。(2)大兴安岭和黑河地区是黑龙江省夏季林火的主要发生地区,大兴安岭地区的夏季林火火因基本都是雷击火,黑河地区的夏季林火火因主要是烧荒。(3)大兴安岭及黑河地区各个县区夏季林火状况有很大不同。(4)6月是大兴安岭雷击火发生最多的时期.6月15~25日是烧荒引发夏季林火的重点时期。黑龙江省6月15~20日间发生的夏季林火次数最多,明显高于其他时间段,过火面积也最大。7月1~5日及8月20日以后均没有夏季林火发生。(5)黑龙江省夏季林火日变化规律较为明显地分为三个阶段。It is found that summer forest fire in Heilongjiang Province has obvious characteristics by studying those fires happened from 2000 to 2004. (1) Summer forest fire in Heilongjiang Province only happened between east longitude 121°12'-130°16' and north latitude 46°53'-53°25'. (2) Summer forest fire in Heilongjiang Province mainly happens in Daxinganling and Heihe areas. Lightening fire is the main reason for Daxinganling area while burning the grass on waste land for Heihe area. (3) Summer forest fires in Daxinganling and different counties in Heihe areas have different features. (4) Lightening fire mostly happened in Daxinganling area in June. Those forest fires caused by burning the grass on waste land mainly happened from June 15th to June 25th. The most time slices of summer forest fire in Heilongjiang Province are June 15th-June 20th and the area of through fire is the biggest. No forest fire happened from July 1st to 5th and after August 20th. (5) The changing rules of summer fore;t fire in Heilongjiang Province can be clearly divided into 3 stages.
