南昌市象湖湿地公园消落带植物景观生态修复策略

Ecological Restoration Strategy of Plant Landscape in Water-level-fluctuation Zone of Xianghu Wetland Park in Nanchang City

为减轻城市湿地公园的消落带生态退化问题(环境污染、水土流失、土壤侵蚀、功能退化等),探求高效的生态修复策略。以南昌市象湖湿地公园为研究对象,在系统分析消落带的共性生态环境问题及现状基础上,提出了相应的景观生态修复策略:1)在广泛调查地域性消落带植物种类及其群落组成的基础上,筛选出适合公园环境的湿生植物种类;2)适度调整消落带的护坡和护岸结构,以自然式护岸为主;3)以乡土的湿生植物为主,建议配植适生植物群落,修复受损的消落带生境,形成特色护岸景观。研究城市湿地公园消落带的植物景观生态修复,有利于实现消落带生境修复、景观游憩、水体净化、减污增汇等生态效益,以构建生态环境友好型的消落带景观。

In order to alleviate the ecological degradation problems(environmental pollution,water and soil loss,soil erosion,function degradation,etc.)in urban wetland park,some efficient ecological restoration strategies were explored.Nanchang Xianghu Wetland Park was taken as research object in this paper,on the basis of systematic analysis of the common ecological and environmental problems and status of water-level-fluctuation zone,and corresponding landscape ecological restoration strategies were put forward:1)On the basis of extensive investigation of plant species and community composition in the regional water-level-fluctuation zone,the wet plant species for park environment were selected.2)The structure of slope and bank protection should be adjusted moderately and it was mainly on natural bank protection.3)It was suggested to plant some suitable plant community to repair the damaged habitat in water-level fluctuation zone and form a characteristic revegetation landscape.The study of plant landscape ecological restoration in the water-level-fluctuation zone of urban wetland park is conducive to the realization of ecological benefits such as habitat restoration,landscape recreation,water purification,pollution reduction and sink increase in the waterlevel-fluctuation zone,so as to construct an ecologically friendly water-level-fluctuation zone landscape.
