摘要自然河流环境是动态的，往往是高生产力，生物多样性的生态系统。纵观历史，人类社会一直在努力利用它们所能提供的利益，但它们的发展在很大程度上忽视了这些利益的多功能性。这至少部分是由于对实际上作为一个综合系统运作的景观要素采取了分割和部门性的看法。特别是在过去的200年里，这种影响是如此之大，以至于今天欧洲几乎所有的大河都在某种程度上受到了管制。河流与其遗传功能景观的脱钩已经被不适当和非一体化的政策机制（如共同农业政策）所支持和鼓励。然而，一个新的管理和政策框架正在从两个并行的倡议中发展出来，这两个倡议可以联系起来，形成一个强大的变革引擎。这两个指令是源自布鲁塞尔的《水框架指令》和源自《生物多样性公约》的《生态系统方法》。科学界现在的一项关键任务是帮助发展支持这些倡议的原理、工具和方法，并使创新政策和决策者能够重新建立支持可持续利用河流集水区的功能联系。
Abstract Natural riverine environments are dynamic, and often highly productive, biologically diverse ecosystems. Throughout history human communities have endeavoured to harness the benefits they can provide, but their development largely has ignored the multi‐functional nature of these benefits. This has been the result, in part at least, of a segmented and sectoral view of landscape elements which in reality work as an integrated system. The impact has been so great, especially during the last 200 years, that today almost all the large rivers in Europe are to some degree regulated. The uncoupling of rivers from their genetic functional landscape has been enabled and encouraged by inappropriate and non‐integrated policy mechanisms such as the Common Agricultural Policy. However, a new management and policy framework is developing out of two parallel initiatives which can become linked to form a powerful engine for change. These are the Water Framework Directive, originating out of Brussels, and the Ecosystem Approach, originating from the Convention on Biological Diversity. A key task for the scientific community now is to help develop the rationale, tools and approach which will support these initiatives and enable innovative policies and decision‐makers re‐establish the functional linkages which underpin the sustainable use of river catchments.
