分析了桥山林区“5．5”特大森林火灾的成因和主要火行为特征及对林下植被的影响，指出该火灾为中强度地表火、高强度树冠火类型。林火发生发展过程可概括为4个时段。火烧过地上一些早生植物大量繁殖或入侵并趋于简单化，原有林分将被以辽东栎为主的阔叶次生林替代。提出开展以生物工程防火为主体的综合防火措施是该林区今后林火管理的主要方向。
The causes of the “5.5” superficial forest fire in Qiaoshan Forest Area and the main fire behavior characteristics and its impact on the undergrowth vegetation were analyzed. The fire was considered as medium-intensity surface fire and high-intensity canopy fire. Forest fire development process can be summarized as 4 periods. Some early burned plants on the ground flourish or invade and tend to be simplistic. The original stands will be replaced by broad-leaved secondary forests dominated by Quercus liaotungensis. Proposed to carry out biological engineering fire as the main integrated fire prevention measures is the main direction of forest fire management in this area.
