摘　　要：长期以来,河道边坡防护主要关注边坡稳定性和行洪、排涝功能,较少考虑硬质化护坡对河道生态系统产生的巨大负面影响,以及人们对城镇水系景观美化的需求。笔者在分析河道边坡发生土壤侵蚀成因及剖析生态护坡技术概念的基础上,着重介绍了河道生态护坡的模式、生态`护坡设计的原则及目前主要的生态护坡材料与方法,并探讨了对不同生态功能需求的河道,应采用不同的生态护坡技术进行边坡防护,以达到既满足河道边坡防护稳定性和安全性的要求,又能发挥河道边坡作为河流生态系统与陆地生态系统之间的过渡带功能所起到的保持水土、净化水体等生态作用。For a long time, the channel slope protection had been focused on its stahihty and flood-control ability. Little was considered about its serious damage to the river ecosystem and the people＇ s demand of beautiful landscape along the water system in city. The reasons of channel slope collapse and the ecological slope protection technology＇ s concept were discussed. The pattern of ecological slope protection, the principles of ecological slope planning and the primary materials and methods of ecological slope protection presently were introduced. As different part of the channel had different ecological function, the different measures of ecological slope protection technology should be chosen. They were used not only to satisfy the demand of stability and security to the channel slope protection, but also to improve the riparian ecosystem＇ s function.
