摘　　要：城市化是城市河流生态系统退化的重要驱动力,也是城市河流生态修复的限制性因素。在分析总结城市河流治理中存在的问题的基础上,阐述了河流生态修复的科学内涵、原则和目标,从岸线形态修复、河床断面恢复、水质改善与净化、生物栖息地重建、河道景观构造等方面提出修复城市河流受损生态系统的方法和改进措施,以期为今后城市河道治理提供技术支持。Urbanization drives strongly degradation of the ecological system of the urban rivers. It is the restriction for the recovery of the urban river ecology. On the basis of the analysis and summarization of issues in the urban river treatment,the scientific contents,principles and objectives of the urban river ecological recovery are described. In terms of bank outline recovery,riverbed section recovery,water quality improvement and purification,reconstruction of biological habitats and river course landscape structures,etc,methods and improving measures for recovering the damaged ecological system of the urban rivers are provided so as to technically support the future treatment of the urban river courses.
