河流生态学研究中的几个热点问题

近年来河流生态系统成为湖沼学研究的重点，很多新理论、新方法被应用到研究中．文章综述了国内外的相关研究，并着重从河流连续、河流的生态需水量、河流生态系统的服务价值与健康评价、河流的生态系统管理以及流域生态学等几个热点方向作了详细论述．作者认为，今后河流生态学的研究应在流域尺度上展开，结合河流健康及生态系统服务评价进行河流生态系统可持续管理研究将是近期河流生态学的重点问题之一．鉴于我国的实际情况，作者建议应该尽快开展相关领域的研究．

Several research hotspots in river ecology

River ecology is a vital field in limnological research, and several new theories and methods have been developed and used in the study of lotic systems. In this article, a summary of these new theories was introduced, which includes river continuum concept, ecological water consumption of river ecosystem, services and health of river e-cosystem, ecosystem management, and watershed ecology. The authors suggested that the research of river ecology should be carried out on the scale of watershed, and that the combination of ecosystem health and ecosystem services could be the key point in the sustainable development management of river ecosystem. Seeing that there are few studies in this area in China, relevant research should be conducted as soon as possible.
