Abstract: The Sanjiang Plain is situated in northeast China. It is one of the areas where marshes are distributed concentratedly and widely in China. Carex lasiocarpa marsh and the marsh with Carex lasiocarpa as dominative species are distributed widely. We chose Carex lasiocarpa marsh as observation object in 1990 and 1991. Marsh evapotranspiration includes transpiration of marsh plants and evaporation of water surface. We used evaporimeters to observe the water level, and calculated the water level amplitude. The evapotranspiration of the marsh is one or two timeS more than the evaporation of water surface in growing season. The larger the vegetation coverage, the greater the daily evapotranspiration. When the vegetation coverage of marsh is less than 10%, the daily evapotranspiranspiration of marsh is dose to the evaporation of water surface. The difference between the evapotranspiration marsh and the evaporation of water surface in sunny days is more than that in cloudy days.
