摘要
2006年鄱阳湖出现了历史上罕见的长时间水位异常偏低的枯水位过程,本文根据实测资料对其特征进行分析;利用水文学方法,分别计算了长江来水偏少和江西五河来水偏少及三峡水库运行对鄱阳湖水位的影响量,作为判断枯水成因的依据,表明鄱阳湖2006年长时间水位异常偏低,主要是由长江上游夏、秋季来水偏少和江西五河秋季来水偏少造成的,三峡水库9～10月蓄水也产生了一定影响。
A process of the lowest water level that was infrequent in the Poyang Lake appeared in 2006. This paper analyzed its characteristics according to observed data, calculated influencing quantity due to the decrease of the inflow from the Yangtze River, operation of the Sanxia Reservior and the decrease of the inflow from the five rivers in Jiangxi. The results show that the low water level of the Poyang Lake for a long time in 2006 was caused by the decrease of inflow from the upstream of the Yangtze River in summer and autumn, and the decrease of inflow from the five rivers in autumn. The other reason is the storage of the Sanxia Reservior from September to October.
