矢作川流域を対象とした水・物質フラックス網の構築と生態系サービス評価モデルヘの適用

Estimation of ecosystem services is an extremely effective method for the sustainable watershed management. It should be understood that ecosystem services have to be analyzed by using physical environment, which have been influenced by hydrological behavior and material load such as sediment flux. Main purpose of this research was set to design of hydrological behavior and sediment flux model on Yahagi river basin, and to suggest the estimation method for ecosystem services. As a result, it was found that hydrological behavior and sediment flux model is a powerful tool for estimating spatial-temporal water quantity/quality. In future study, based on this methodology, effects of various policies implementation would be evaluated.
