摘　　要：探讨了1998年长江、松花江和嫩江流域发生特大洪涝灾害的原因。有自然因素的影响。但人为因素诸如滥伐森林、围湖造田和在河滩地搞违章建设等促成此次洪水灾害的严重性。山区林区生态环境恶化,山下平川地区遭殃,历来如此。应强化保护森林,加快长江中上游防护林体系生态工程建设,充分发挥山地森林的水文生态效应机制,对江河湖泊及其流域进行综合治理,协调行动。The paper analyzes the reasons of flood in Changjiang River and Songhuajiang River and Neijiang River,certainly,there exist some nature factors,but the most important reasons are human activities,such as over cutting of forest resources,expanding farm lands around lakes and illegal constructions along rivers.The worse environment in mountain ar- eas,the larger economic benefit damages in lowland areas,so,the author suggest that it should be urgent to protect forest resources and afforestate in the upper of Changjiang River, and strength forest water environmental roles.
