Analysis of the Vegetation Change of Black Pine Forest along Kujukuri coast by Aerial Photographs

Abstract

The area of coastal black pine forest along Kujukuri coast is decreasing. It is important to understand the change of the coastal black pine forest. In this study, we analyzed the change of pine forest by using multi level slice classifier with aerial photographs taken in 1974 and 2006. From the comparison of two classification results, we confirmed that the area of the black pine forest has decreased. In particular, the decrease of the black pine forest was shown along the road that passed the center of the forest. We also calculated the change ratio with which the black pine forest in 1974 changed to other vegetation in 2006. The change ratio differed largely depending on the place and was mostly around 20-60%.
