| 摘 要： | 在分析当前森林防火等级评定现状的基础上，阐述有序分割类的属性识别方法在林火等级评定中的应用。在已有的火险等级分类矩阵的基础上，给出火险因子属性测度的一般方法，分析不同置信度值入对等级评定的影响，并结合具体实例加以分析，证实该方法使用简单，也科学合理，可推广应用到林业领域有关“强弱”、“程度”、“等级”、“适宜性”等定性问题的定量化评定工作去。

| Abstract: | On the basis of analysis of current situation of fire danger grade assessment, the application of attribute identification method of ordered partition sort in fire danger grade assessment was explained. According to existing matrix of fire danger grade system, conventional methods of fire danger factor were shown in this paper. Different confidence level λ which effected grade assessment was analyzed. At last, it was confirmed that this method was simple and reasonable, and it could be applied in forestry works to quantify some qualitative problems about strong and weak, degree, grade, and suitable characteristic and so on. |
