1998年大洪水后 ,为治理江河流域、根治水患、进行灾后重建 ,国务院及时提出了“封山植树 ,退耕还林 ;平垸行洪 ,退田还湖 ;以工贷赈 ,移民建镇 ;加固干堤 ,疏浚河湖”的方针 .根据 1998年冬至 1999年春鄱阳湖区“平垸行洪 ,退田还湖”实施情况以及 1999～ 2 0 0 3年“平垸行洪 ,退田还湖”的规划方案 ,初步分析了“平退”后长江再遇 195 4、1995、1998等年型洪水湖口水位的降低值 ,从而阐述“平垸行洪 ,退田还湖”的重要作用与意义 .

After the big flood in 1998, in order to harness rivers and bring floods under permanent control and carry out post-disaster reconstruction, the State Council promptly proclaimed the policy of 'close hillsides to plant trees, return grain plots to forestry; remove lakeside embankments for releasing floods, and return grain fields to lakes;relieve people in disaster area by giving them employment,relocate settlements and construct new towns;consolidate major embankments, and dredge rivers and lakes'. On the basis of actual practice from winter 1998 to spring 1999 of implementing the policy of 'removing lakeside embankments for releasing floods and return grain fields to lakes', and the 1999～2003 program of implementing the policy in Poyanghu Lake area, this article preliminarily analyzes and predicts the decrease of the water level at Hukou if the floods of 1954-, 1995- and 1998-model recur, thus explaining the effect and significance of the policy.
