摘要
顺直河道存在形态单一、生态退化等问题,修复河道的蜿蜒性是改善其生态环境的重要措施。针对多数顺直河道具有河宽受限、短期防洪为主等特点,提出在低水期通过设置生态修复建筑物以营造低水蜿蜒流动形态的理念;根据水动力和生态要求,提出蜿蜒河槽设计参数的确定方法,布置合适的生态修复建筑物以构建低水蜿蜒流动形态;结合顺直河道特点与修复目标要求,对低水蜿蜒河槽构建的应用前景作了展望。
Due to the problems of straight channel such as single morphology and ecological degradation, restoration of meandering river is an important measure to improve the ecological environment. Based on the characteristics of most straight channels that river width is limited and the construction priority is given to short-term flood control, a concept on creation of low-water meandering flow form by setting the ecological restoration structures during low-water period is p design parameters of roposed. According to the hydrodynamic and ecological requirements, the method to determine meandering river channel is put forward to arrange appropriate layout of ecological restoration structures to build low-water meandering flow form. Combining with the characteristics of straight rivers and their restoration objectives and requirements, the application prospect of establishing low-water meandering channel is also given.
