摘　　要：分析对比了河道治理中的生态治理措施的适用条件,并以龙川县鹤市河治理项目为例,探讨了河道生态治理设计中遇到的典型问题和解决方法,以期为河道生态治理设计优化和类似工程项目提供参考。通过实施建设生态透水坝和橡胶坝、种植挺水植物、改造滩地等技术措施,河道内整个生态系统逐渐趋于完善,稳定发挥水体自净能力。在微生物、维管束植物、浮游生物以及稀释、沉淀和絮凝等多方面的综合作用下,干流水质得到提升和改善,达到Ⅲ类水质标准,实现了设计目标要求。The applicable conditions of ecological governance in the river management were analyzed and compared,and the Heshi River regulation project in Longchuan County was taken as a case to discuss the typical issues and solutions encountered in the design of river ecological governance,so as to provide reference for the optimization of river ecological governance design and similar projects.Through the implementation of the construction of ecological permeable dam and rubber dam,planting emerged plants,renovating the beach land and other technical measures,the whole ecosystem in the river gradually improved,and the self purification ability of water body was stably developed.Under the comprehensive action of microorganisms,vascular plants,plankton,dilution,sedimentation and flocculation,the water quality of the main stream was improved and reached the class III water quality standard and achieved the design goal.
