湖泊陡岸带生态建设基底修复工程技术

Rehabilitation Technique of Foundation Base for Ecological Belt Construction in Littoral Abrupt-slot of Lake

文章介绍最新开发的湖滨陡坎沿岸水域基底修复技术,主要采用人工方法在需要进行大型水生植物群落恢复的湖滨陡坎沿岸的水域实施基底修复工程措施,在目标水域边界构筑水下围埝,采用绞吸式挖泥船将疏浚的湖泥按设计高程要求吹填至基底修复工程区内,形成缓坡浅滩,改善湖泊沿岸带自然条件,为湖泊沿岸带生态修复创造良好的生境条件。文章对该技术方案、工程效果进行了介绍,并将本技术与同类技术特点进行对比分析和探讨。

The latest developed technique for foundation base rehabilitation is to artificially implement foundation base rehabilitation engineering in littoral abrupt-slot of lake where the restoration and reconstruction of macro-hydrophytes will be carried out.The underwater enclosure was built along the boundary of target water body and the lake bottom sludge was filled into the enclosure by twisting-suction dredging ship according to designing elevation for the purpose of formation of slope riffle,which will improve natural condition of littoral zone of lake,and create favorable habitation condition for ecological restoration in littoral zone of lake.The technical scheme and engineering effect was introduced,with analysis of characteristics with other similar techniques.
