Abstract—The issue of spatial characterization in the context of illegal garbage dumping issues in mountainous regions has emerged as a pressing concern in recent years. The methodology involves analyzing the environmental factors that lead to illegal dumping of garbage problems by studying case examples of trash waterfalls in mountain areas and conducting a literature review. Geographic information systems supplement this analysis to determine the spatial distribution of illegal dumping of garbage problems and the potential spatial factors that lead to their occurrence. The expected results include the establishment of a multiple-ring buffer of the spatial factor maps and then converting vector data into raster data of 20 m in length and width using a Geographic Information System. The Geographic Information System “raster calculation” function is then used, to sum up the scores of the illegal dumping of garbage potential classification layers to create the raw scores of the possible map of illegal garbage dumping. Finally, the box-and-whisker plot percentile method is used to identify statistically significant outliers, considered the threshold score for recognizing high-potential areas. This study provides a more systematic concept and methodology to help people solve the problem of dumping in the study site in the mountainous areas of Taiwan.
