世界上79个大型河流洪泛区生态系统中的大多数已经被人类活动改变，其余的可能很快就会改变。生态系统管理的作用是引导而不是阻碍自然进程。本文简要介绍了洪泛区和洪泛区管理的历史，然后重点介绍了大型河流洪泛区生态系统的重要性，以及改变自然河流过程、功能和连通性的一些后果。自然资源机构通常采用的以物种为重点的管理系统与河流泛滥平原管理的生态系统方法形成对比。生态管理的定义是利用生态系统的自然驱动力和可变性，以维持或恢复生物完整性为目标。洪水脉冲也是一个焦点，因为它们驱动了系统和过去几年几大洲的大洪水。参考文献88篇，10个无花果。
Most of the 79 large river floodplain ecosystems in the world have been altered by human activities and the rest are likely to be altered soon. Ecosystem management works to guide rather than thwart, natural processes. This article describes briefly the history of floodplain and flood plain management and then focuses on the importance of large river-floodplain ecosystems and some of the consequences of altering the natural river processes, functions, and connectivity. The species-focused management system typically employed by natural resource agencies is contrasted to the ecosystem approach to river-flood plain management. Ecological management is defined as working with the natural driving forces and variability of the ecosystems with the goal of maintaining or recovering biological integrity. Flood-pulses are also a focus because they drive the system and the great floods on several continents in the last years. 88 refs., 10 figs.
