ZHANG Wei-dong,TAI Shan-shan,WANG Xue-feng(College of Life Sciences,Liaoning Normal University,Dalian 116029,China)  
Taken the watershed in the upper reaches of Raoyang River as a study area,the annual water equilibrium was calculated by using a modified model of stand evapotranspiration,which was a combined method of water equilibrium and estimation.The results showed that the evapotranspiration was the main form of water output in the upper reaches of Raoyang River Watershed.The plant cover in this region was seriously affected by drought due to strong evaporation.
