摘　　要：蒸散发在很大程度上影响湿地的水热平衡,宏观掌握湿地区域的蒸散发量对于进一步研究湿地生态系统水文———大气———土壤、植被界面能量转化等过程变得尤为重要。本文在遥感技术基础上,基于地表平衡原理的SEBAL模型,对北京野鸭湖湿地区域蒸散发情况进行模型构建,利用1998年和2004年Landsat TM/ETM卫星数据获取相关地面特征参数及该地区的日蒸散发量,并结合水资源和植被盖度分析研究野鸭湖湿地区域日蒸散发量的动态变化情况。Evaportranspiration has a great extent influence on the balance of wetland water and energy. It is very important to grasp macroscopically the wetland regional evaportranspiration for the sake of farther researching the wetland ecosystem of hydrology-atmosphere-soil and vegetation interface. Based on the remote sensing technology, the paper established SEBAL model on the foundation of the earth surface balance for Beijing Yeyahu wetland regional evaportranspiration, and used Landsat TM/ETM satellite data to gain the related ground characteristic parameters and the daily evaporation, eventually combined with water resources and vegetation fraction to analyze and research the dynamic change of Yeyahu wetland regional daily evap- oration.
