| 摘 要： | 1998年长江洪水是自1954年以来又一次全流域性特大洪水，其特点是：气候异常，受厄尔尼诺/拉尼娜影响；水位高，持续时间长；上中下游洪水遭遇；受灾经济损失大。1998年洪水给人们的警示是：历史洪水多成组出现，防洪不能松懈；平垸行洪，势在必行；分蓄洪区不能形同虚设；大规模退田还湖，并不现实可行；长江上游分洪是防洪上的奇迹；调用“土壤水库”是防洪治本之策。

| Abstract: | The flood in the Changjiang River in 1998 was another catastrophic and whole basin one since 1954, the characteristics of which were: unusual climate, high water level, long continued time, the encounter of floods in the upper and the middle or the lower reaches, big economic loss affected by the flood. The warnings of the flood for us are: continued floods in the past, unremitting flood preventing, imperative razing the protective embankments in the flood lands and draining flood, effective flood diversion and flood storage regions, unrealizable returning farmland to lake in a large scale, marvellous water diversion in the upper reaches in the Changjiang River, transferring soil reservoir for taking radical measures. |
