摘　　要：河溪缓冲带位于陆地生态系统与水生生态系统的之间,是河溪生态系统的重要组成部分,具有多种生态功能。着重介绍了河溪缓冲带的物种天堂、养分来源、稳固河岸、改善水质、景观价值、缓解影响这6种功能。由于现在交通和建设用地的不断增加,河溪缓冲带的人为破坏现象严重,亟需得到科学的管理和恢复。提出了3条缓冲带科学管理的基本原则,为不同地域、不同等级的河溪缓冲带的建设和恢复提供了指导。并以北京市海淀区内的南沙河河溪缓冲带的情况为例,加以印证说明。Stream buffer strips are located between the terrestrial ecosystem and the aquatic ecosystem, which are also the important composition of stream ecosystem. This paper emphasizes the introduction of six ecological functions of buffer strips, that is, species heaven, nutrient source, river bank stabilization, water quality amelioration, landscape value and harmful impact alleviation. However, disturbances caused by human activities to stream buffer strips become serious due to a great increment in the land for construction and transportation. Therefore, there is an urgent need in scientific rehabilitation and management. For this reason, we present three basic principles of scientific management of stream buffer strips as the guidelines for the rehabilitation and construction of stream buffer strips in different grades in different areas. By taking the Nansha River located in Haidian district of Beijing for an example, we illustrate the functions of stream buffer strips and the scientific management principles.
