摘　　要：根据2005年盘锦芦苇湿地监测站的小气候梯度监测数据和涡动通量观测数据,结合芦苇生理生态特性观测资料,采用波文比-能量平衡法、Penman-Monteith模型对盘锦湿地芦苇群落蒸发散进行模拟,并与涡动相关系统的实测资料进行比较。结果表明:Penman-Monteith模型更适合芦苇群落蒸发散的模拟,可为芦苇湿地蒸发散的计算提供依据。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.
