Abstract
Quantification method for regulation service-related scores was developed to evaluate the current status and near-future status of four tidal flats in Tokyo Bay. We modified the methodology of the Ocean Health Index and applied to shallow coastal ecosystems in Japan. The data of benthos biomass, sedimentary organic matter, and other environmental variables were collected to quantify three functions (suspended particle removal, organic matter decomposition, and carbon storage). The scores of suspended particle removal and organic matter decomposition were high in the tidal flats where benthos are abundant. The function of carbon storage was related to the sediment quality. Our estimation indicates that the regulating services would be high in high biological-productivity areas.
