林地潜在人为火发生模型的研究

Study on the Model of Potential Human Caused Forest Fire Occurence

林地潜在人为火的发生次数多少,反映森林火灾的危险程度.据对进入林地身带火种的人数,单位人一天内用火次数、细小可燃物湿度和林地潜在火险系数的分析研究并建模,最后建立一个综合反映林地潜在人为火发生频次的数学模型,可直接计算当时天气条件下某林地可能发生的人为火次数.

The occurence frequencies of human caused fire in forest land reflect the dangerous degree of forest fire. We made analyses and models based on the following data;the numbers of peoples who went into the forest land and carried fire sources frequencies of fire use per person per day ,humidity of fine flamable materials and potential fire occurence indeces. A mathematical model was constructed, which comprehensivly reflect the frequencies of potential human caused fire in forest land ,and the frequency of human caused fire in a given forest land and given weather conditions can be calculated directly from the model.
