云南省森林火源特点分析

Analysis on the Characteristics of Forest Fire Sources in Yunnan Province

[目的]探讨云南省森林火源特点。[方法]对2004—2014年云南省产生的森林火灾次数及火源特点进行了研究。[结果]云南省生产性火源和非生产性火源都是森林火灾的主要原因,但非生产性火源所占比重更大。生产性火源中烧荒烧炭影响最大;非生产性火源中,野外吸烟、小孩玩火、上坟烧纸、取暖做饭和智障弄火是主要火源。其中,非生产性火源具有明显的季节性特点和时段性特点,季节主要集中在3—5月,时段主要集中在09:00—13:00和15:00—20:00。[结论]该研究可为云南省森林防火的火源管理提供参考。

[Objective]To analyze the characteristics of forest fire sources in Yunnan Province.[Method]The fire times situation of forest fire source and the characteristics of fire source were studied in Yunnan Province during 2004-2014. [Result]The results showed that the production fire and non-productive fire were the main reason of forest fire. And the proportion of non-productive fire sources was bigger than production fire. In production fire sources burning charcoal was the most affected. In non-productive fire sources,wild smoking,children playing with fire,grave burning paper,heating cooking and dementia fire were the main sources of fire. The non-productive fire source has obvious seasonal characteristics and period characteristics. The season was mainly concentrated between March and May,and the time was mainly concentrated at 9∶ 00-13∶ 00 and 15∶ 00-20 ∶ 00. [Conclusion]The study can provide reference for fire management of forest fire prevention in Yunnan Province.
