Simulating evapotranspiration of Phragmites communis in Panjin Wetland

YU Wenying~1 ZHOU Guangsheng~(2,3) ZHOU Li~3(1.College of Water Conservancy,Shenyang Agriculture University,Shenyang 110161;2.Institute of Atmospheric Environment,China Meteorological Administration,Shenyang 110016;3.Laboratory of Quantitative Vegetation Ecology,Institute of Botany,the Chinese Academy of Sciences,Beijing 100093)  
Based on the microclimate gradient observation,eddy covariance observation and ecophysiological observation in Panjin wetland ecosystem research station in 2005,the evapotranspiration of Phragmites communis was simulated by Bowen ratio energy balance method and Penman-Monteith model.The simulated values were validated by the observed data from eddy covariance system.The results showed that Penman-Monteith model was the better one to simulate the evapotranspiration of Phragmites communis.This research would provide the evaluation method for the evapotranspiration of Phragmites communis.
