摘　　要：从渠道空间形态、断面形式、材料、结构、尺寸、经济等多方面对生态渠道与传统渠道进行比较,分析生态渠道在寒区应用的优势,既满足渠道基本的工程性能,防止渗漏、提高输水效率,同时又能符合动植物生态宜生的特点,维护渠道生态系统完整性,能够改善水质和环境的自净能力。生态渠道在经历若干个冻融周期后,具有良好的抗冻耐久性。Comparing ecological channels with traditional channels from the aspects of channel space form,section form,material,structure,size and economy,the advantages of the application of ecological channels in cold region is analyzed,which can not only meet the basic engineering performance of the channels such as prevent leakage,water conveyance efficiency,but also meet the characteristics of animal and plant ecology,maintain the integrity of channel ecosystem,and improve the self-purification ability of water quality and environment.At the same time,the ecological channel is applied in the cold region and has good frost resistance durability after several freeze-thawing cycles.

关 键 词：生态型渠道 防渗漏 生态宜生 环境自净
