摘要
云南松林区发生的森林火灾是多种自然因素和人为活动综合作用的结果。通过对四川省云南松分布区不同区域与林火有关的主要气候因子分析及综合值的比较,结合地形地貌、植被状况和人为活动等多种因素,将我省云南松分布区划分成5个不同等级的火险区,并提出了相应的护林防火对策。
The forest fires in Yunnan pine forest areas resulted from many kinds of natural factors and human activities. This paper analyses main climatic factors related to forest fires in various Yunnan pine forest areas and compares their comprehensive values. And according to varied factors such as topography , landforms, vegetation and human activities, the Yunnan pine forest areas in Sichuan are categorized into five divisions with different fire danger rating, and some relevant countermeasures are suggested for forest and fire protection.
