SOIL EROSION ZONE ESTIMATION METHOD AND SOIL EROSION ZONE ESTIMATION APPARATUS
PROBLEM TO BE SOLVED: To provide a soil erosion zone estimation method and a soil erosion zone estimation apparatus that can estimate a risk of soil erosion while considering influences derived from animals.SOLUTION: The soil erosion zone estimation method forecasts a vegetation recovery level indicating an extent of recovery of forest floor vegetation for each area of a predetermined size on the basis of vegetation data including forest floor vegetation data of plants, topographic data and weather data. The soil erosion zone estimation method forecasts habitat distribution of animals for each area on the basis of vegetation data, topographic data, weather data and ecological data indicating the ecology of animals that harness plants. The soil erosion zone estimation method forecasts a risk of shallow landslide indicting a risk that shallow landslide of soil occurs for each area on the basis of vegetation data, topographic data and weather data. The soil erosion zone estimation method determines a risk of soil erosion for each area on the basis of the forecasted vegetation recovery level, the forecasted habitat distribution and the forecasted risk of shallow landslide.SELECTED DRAWING: Figure 1
【課題】動物由来の影響を加味した土壌侵食リスクを推定できる土壌侵食地域推定方法および土壌侵食地域推定装置を提供する。【解決手段】土壌侵食地域推定方法は、植物の林床植生データを含む植生データと、地形データと、気象データとに基づいて、所定の大きさのエリアごとに林床植生の回復の度合いを示す植生回復度を予測する。土壌侵食地域推定方法は、植生データと、地形データと、気象データと、植物を利用する動物の生態を示す生態データとに基づいて、エリアごとに動物の生息分布を予測する。土壌侵食地域推定方法は、植生データと、地形データと、気象データとに基づいて、エリアごとに土壌の表層崩壊が発生するリスクを示す表層崩壊リスクを予測する。土壌侵食地域推定方法は、予測した植生回復度と、生息分布と、表層崩壊リスクとに基づいて、エリアごとに土壌侵食リスクを判定する。【選択図】図１
