摘　　要：分析了三峡工程蓄水后影响枯水位变化的主要因素,采用1982—2002年水文资料对荆江河段设计水位进行计算,参照水沙数学模型所得预测值,并利用蓄水以来的荆江河段枯水位对其进行复核,得到的设计水位偏于安全,既体现了蓄水后的影响,又反映了设计水位的变化趋势。This paper analyzes main factors influencing the low water level after the impoundment of the Three Gorges project, calculates the designed stage of Jingjiang reach according to the hydrological data during year 1982 and 2002, and checks the stage referencing the predicted value obtained from the water-sand mathematical model and according to the low stage of Jingjiang reach after the impoundment, we get the designed stage which is relatively safe and which reflects not only the impact of the impoundment , but also the variation trend of the designed stage.
