Analysis of the Influence of Road Landscape Elements on the Occurrence of Illegal Dumping in and around Urban Areas
Akio SHIINO （Hokkaido Institute of Technology）
Abstract:
This study identifies the characteristics of illegal dumping sites in and around an urban area, and identifies the landscape elements of roads where illegal dumping occurs frequently in order to develop means to curb illegal dumping. In the study, GIS data was used to classify 6,248 illegal dumping sites. Special cluster analysis of the data was used to select 32 roads where there has been frequent illegal dumping. Comparing the landscape elements of these roads with other roads connecting to them, road landscape patterns were classified into three types based on their distinguishing traits. Type I was characterized by the influence of artificial materials, Type II by plant masking and Type III by complex factors. Several landscape elements that promote or restrain the occurrence of illegal dumping were identified for each type.
