Influence of geographical and environmental factors on human-caused fires in Tahe area

In this paper,we used the spatial analysis tools in ArcGIS10.0and Logistic regression model imbedded in SPSS 19.0to 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∶1and 1∶3conditions,respectively.It was also found that the rate of random sample selection affects the parameter estimation of the model.
