中文摘要：

河岸带是指河水、陆地交界处的两边，直至河水影响消失为止的地带。作为水生生态系统与陆地生态系统的交错地带，河岸带成为二者进行物质、能量、信息交换的重要过渡地带。随着非点源污染的加剧，河岸带由于其对非点源污染的控制作用和对水质的净化作用，越来越受到关注。由于其特殊的地理位置，它还有其他的生态功能：保护生物多样性、廊道作用、巩固堤岸、经济功能、景观价值等。目前，从微观、中观、宏观三个尺度上对河岸带研究都有进行并有待深入，退化河岸带的重建和恢复研究对于河岸带发挥其生态功能越来越重要。

英文摘要：

Riparian zone is an area extending from two edges of a river to where influence of the fiver disappears. As interleaving region between river and land ecological systems, riparian zone is an important transitional region for them to exchange substance, energy and information. Nowadays non - point pollution is becoming more and more serious, people are paying more attention on riparian zone, because of its obvious function in controlling non - point pollution and purifying water. Because of its special location, it has some other ecological functions： protecting bio - diversity, corridor function, consolidating river - bank, economical function, landscape value and so on. Nowadays, studying riparian zone from macro- , mid- and micro- scales has been progressing and needing further research. Also, restoration and rebuilding of degraded riparian ecosystem is becoming more and more important for riparian to act its ecological functions.
