Evaluating location and layout of a Forest Belt based on The Effect of Wind Protection in Shonai Coastal Sand Dunes

Abstract

In this study, the authors examined the location and layout of a forest belt mainly consisting of Japanese black pine in Shonai Coastal Sand Dunes based on their effect of protection against wind erosion. Firstly, we collected data on topography, components and structures of the forest belt, and wind velocity in the area including shifting sand prevention forest, windbreak for cropland, and top of sand dunes where wind erosion is significant. We then organized the data based on their effect of wind protection and determined suitable location and layout of the forest belt. As a result, necessary conditions for the forest belt with adequate wind protection in this area were selected. Furthermore, we were able to confirm that tree height could be used as an indicator when deciding the width of a forest belt.
