摘要
以环巢湖区域典型圩田湿地——许桥联圩为例,基于圩田湿地水文环境紊乱、生境破坏、景观特色弱化等生态问题,提出因地制宜的生态修复策略:1)在保护现有水网格局的基础上,合理设计渠、塘、水闸和泵站等,形成层级有序的水生态系统,提高湿地调蓄能力;2)保护圩田原生态,因地制宜构建沼泽、生态塘、生态岛等多样化生境,提高生物多样性;3)延续原空间特色为主,丰富植物景观风貌、完善配套设施等,打造低干扰性生态景观.湿地修复效果预期较好,可为其他类似圩田湿地生态修复提供借鉴.
Abstract
Taking Xuqiao polder,a typical polder wetland around Chaohu lake,as an example,this paper puts forward the ecological restoration strategy of polder wetland to solve the problems of hydrological environment disturbance,habitat destruction,and weakening of landscape characteristics.The main strategies include:1)On the basis of protecting the current water network pattern,rationally designing canals,ponds,sluices,pumping stations,etc.,to form an orderly water ecosystem and improve the wetland regulation and storage capacity;2)Protect the original ecology of polders,and build diversified habitats such as swamps,ecological ponds and ecological islands to improve biodiversity;3)Maintain the characteristics of the original space,appropriately enrich the plant landscape,improve the supporting facilities,etc.,to create a low-disturbance ecological landscape.The effect of wetland restoration is expected to be good,which will provide a reference for ecological restoration of other similar polder wetlands.
