Summary:This paper discusses the distribution properties of pan evaporation that is an index of the evapotranspiration in a small wetland. The evapotranspiration is very important to a small wetland. It is to influence the wet condition of the surface very much. Kawaminami wetland in Miyazaki Prefecture is the studied site. In this wetland, the values of pan evaporation at many locations were recorded. Furthermore, groundwater levels and meteorological elements were observed. As a result, distribution of pan evaporation has been related to distribution of surface solar radiation and surface moisture condition in wetland. Therefore relations of pan evaporation and evapotranspiration were considered and arranged a complementary relationship. The complementary relationship has accorded with distribution of pan evaporation in wetland. Finally evapotranspiration of the wetland was able to be estimated.
