The Relationship Between Tree Growth and the Decrease in Visible Islands in Archipelago

Abstract

Japan is a tourism-rich country with abundant water resources, and its archipelago landscapes are particularly important features. To capitalize on the trend of tourism recovery, the management and improvement of archipelago landscapes are crucial. However, in recent years due to fiscal constraints, many tourist areas have neglected green space management. The growth of trees and other vegetation has a significant impact on the landscape. This paper focuses on the Kujūku Islands as the main research subject. Additionally, this paper focuses on green space management, using the identifiable number of islands as an indicator to evaluate archipelago landscapes. Using mathematical models such poisson point process, we demonstrate that when the central field of view overlooking the landscape is obstructed, the number of visible islands decreases significantly. The influence of tree growth on the visible sea surface area and the visible islands is shown.
