摘　　要：长江消落带岸坡常年在水位上涨、下跌过程中反复被冲刷,导致植被破坏、生态脆弱,使其消落带区域丧失了过滤、拦截功能。以重庆广阳湾片区长江水位为160.00~170.00 m的区域为例,进行消落带治理方案的研究,采取“生态固土网垫+植被”相结合的方法保持岸线的稳固性,同时植被生长后形成滨水景观带,形成多层次、结构复杂的消落带复合林泽系统。结果表明,土壤保持率达98%以上,工程实施的效果良好。The bank slope of the fluctuating zone of the Yangtze River is repeatedly scoured for years as the water level rises and falls,which results in the vegetation deterioration and ecological fragility and makes the fluctuating zone lose its function of filtering and intercepting.Taking the area with the water level ranging from 160.00 m to 170.00 m in the Yangtze River in the Guangyang Bay area of Chongqing as an example,this paper studies the treatment scheme for the fluctuating zone and adopts the method of“ecological net mat for soil consolidation+vegetation”to maintain the shoreline stability.In addition,the waterfront landscape zone and a multi-level and compleXcompound forest system of the fluctuating zone are formed after vegetation growth.The results show that the soil retention rate is more than 98%,and the project implementation has a favorable effect.
