The purpose of this study is to obtain rare knowledge of countermeasures against disasters utilizing ecosystems by clarifying the characteristics of trees that are expected to have sediment discharge buffer effects based on universal environmental field conditions such as tree spacing, area, average tree age, average tree height, and slope inclination. Based on numerical geographic information and aerial photography using a UAV, the sediment production buffer effect was verified by focusing on the environmental conditions such as the distance between trees. As a result, cases of sediment buffering were extracted in areas where sediment production was concentrated. The possibility that environmental factors that form a forest zone, such as the distance between trees, contribute to the sediment buffer was also identified. The environmental factors of forest formation change over time, and the need for maintenance and management of forests becomes important.
