基于水安全与生境营造相融合的湖泊堤岸生态化改造方案研究

Study on Ecological Reconstruction Scheme for Lake Embankments Based on Integration of Water Security and Habitat Construction

摘要:

为研究风浪较大区域湖泊堤岸的生态化改造方案，以淀山湖堤防达标及岸线生态修复工程（一期）为例，梳理淀山湖岸线现状存在的问题，分析开展水生态修复的必要性。同时，根据风浪及现状水生态情况选取了适合开展水生态修复试验的岸段，充分考虑波浪对植物生长、护岸稳定的影响，并结合岸后景观风貌，通过相关分析计算，提出较为新颖的护岸改造方案。此方案兼顾水安全、水生态、水景观，且经济、可行，在类似工程中有着较大的应用前景。

Abstract:

To study the ecological reconstruction scheme for lake embankments in areas with significant wind and wave activity, taking the Dianshan Lake Embankment Upgrading and Shoreline Ecological Restoration Project (Phase I) as an example, the existing issues in the present shoreline of Dianshan Lake are sorted out, and the necessity of water ecological restoration is analyzed. The shoreline sections suitable for the ecological restoration trials are selected according to the wind-wave conditions and current aquatic ecosystems. The impacts of wave on plant growth and embankment stability are fully considered. And combined with the waterfront landscape features, an innovative revetment reconstruction scheme is proposed through the relevant analysis and calculation. This scheme takes into account water security, water ecology and water landscape, and is economically feasible, which has the greater application prospect in the similar projects.
