Abstract

It is thought that a salt marsh located at coastal urban area absorbs and emits large amounts of carbon dioxide (CO₂). In this study, a field investigation on CO₂ budget was conducted at Osaka-Nanko bird sanctuary, and CO₂ fluxes were measured at tidal flat, sea surface and reed field by using chamber methods in order to estimate CO₂ budgets of the salt marsh. The results of this study were as follows: (1) CO₂ fluxes of tidal flat and reed field were one order larger than that of sea surface. (2) It was estimated that CO₂ flux emitted from tidal flat was 3.26 g/m²/day and CO₂ flux absorbed by reed grass field was 1.53 g/m²/day in October 2013. (3) It was suggested from the result of seasonal change of fluxes that the absorbed amount of CO₂ becomes larger on summer than on autumn.
