| 摘 要： | 应用1974年—2009年间人为火的空间地理坐标,结合研究地的基础地理信息及矢量化林相图,应用ArcGIS10.0中的空间分析工具和SPSS19.0的逻辑斯蒂回归模型深入分析地形环境因素对人为火发生的影响。研究结果表明"到铁路距离"对人为火的影响显著,其次,在1∶1和1∶3选取随机点条件下人为火发生分别与"优势树种"和"林型"显著相关。本文研究显示在运用"随机点"方法进行相关性分析时,随机点选取数量对模型拟合结果有一定影响。

| Abstract: | In this paper, we used the spatial analysis tools in ArcGIS10.0 and Logistic regression model imbedded in SPSS 19.0 to identify the impact of human-activity and geographical factors on forest fires, based on the coordinates of human-caused fires during 1974-2009 and the basic geographical map. The results showed that "the distance to railway" has a significant impact on the human-caused fires. Moreover, "the dominant tree" and "the forest type" are significantly correlated with human-caused fires under 1:1 and 1:3 conditions, respectively. It was also found that the rate of random sample selection affects the parameter estimation of the model. |
