FEASIBILITY OF FUNCTIONAL USE OF REED-FIELD TO REMOVE EXCESS NUTRIENT AT COASTAL AREA

Abstract

The Common Reed (Phragmites communis) is observed commonly along the coastal area and the river mouth, and is known by its high capability of the nutrient uptake. For the feasibility study of the functional use of the reed-field with its ecosystem to remove the excess nutrient, field observation was conducted at the small tidal-marsh of the Tokyo Bay. This reed-field is found to play an important role for the nutrient cycle at the marsh, and shows high nutrient uptake rate under the natural condition.
