摘要：

A spatial autocorrelation analysis was conducted to examine the distribution of wildfires in the Idyllwild quadrangle of the San Jacinto Mountains, San Bernardino National Forest, California. Moran's I coefficients of past fire activity were generated based on different spatial weighting functions. Comparisons among spatial weighting functions indicate that the contiguity weight can be used to define the spatial term of neighborhood effects. Data overlays of multiple GIS layers derive the explanatory variables for modeling the distribution of wildfires from logistic regressions. Without incorporating the spatial term, fire rotation is the leading factor of fire occurrence. The model is improved significantly when the spatial term is included. The result suggests that neighborhood effects are a primary factor in the distribution of wildfires.
