【 摘 要 】

The Poyang lake basin has been affected seriously by drought and flood. The monthly precipitation data from 1951 to 2013 were used to analyze the variation law of drought and flood in Poyang lake basin based on standardized precipitation index in different time scales. Results indicated that the Poyang lake basin is suffered with frequent droughts and floods and the standardized precipitation index is suitable to analyze the law of drought and flood for the Poyang lake basin.
