摘要：

A relationship was sought between species distribution and seasonal change in the redox property of peat in a floating mat in Mizorogaike Pond, central Japan. The mat surface experienced an annual submergence-emergence cycle due to its sinking-rising movement. Redox potential (Eh) of the surface peat showed little difference between communities in the mat in the submergence season (January-June) and early emergence season (July-August). However variation in Eh among communities was dear in the late emergence season (September-December). Among seven communities in the floating mat, the Menyanthes trifoliata-Rhynchospora fauriei, M. trifoliata-Eriocaulon sikokianum-E. hondoense f. pilosum, Sphagnum cuspidatum and M. trifoliata-Carex thunbergii communities had high Eh (400-600 mV) in the late emergence season, while the Menyanthes trifoliata and Phragmites australis-M. trifoliata communities had lower Eh (200-400 mV). The M. trifoliata-Isachne globosa community was intermediate (300-500 mV). The earlier the emergence of the peat surface began, the higher the Eh became in the late emergence season.
