湖滨带生态功能对城市湖泊健康生态系统的影响研究

Research on the Influence of Lakeside Zone Ecological Function on Urban Lake Healthy Ecological System

以武汉市典型城市湖泊墨水湖不同类型湖滨带为研究对象,基于原子法(AAS)、地累积指数法和潜在生态风险指数法综合分析、评价墨水湖存在的重金属污染等生态风险状态,比较分析不同类型湖滨带对城市湖泊健康生态系统的影响。结果表明:湖滨带对城市湖泊污染具有控制与净化作用,不同类型湖滨带其截污与净化能力存在明显差异,林田型湖滨带具有较好的生态修复功能,而堤岸型湖滨带对污水的耐受能力和净化降解效果相对较弱。

Taking the different type lakeside zones of Moshui Lake of Wuhan typical urban lake as the research subjects, the paper assessed the ecological risk of heavy metals pollution in lakeside zone of Moshui lake, and comparatively analyzed the influence of different type lakeside zones on urban lake ecological health based on the atomic absorption spectrophotometry （AAS）, the geo-accumulation index method and the potential ecological risk index method. The experimental results showed that lakeside zones had control and purification role for the urban lake pollution. Different types of lakeside zones has different sewage interception and purification capacities, such as the lakeside zone that exists plants and fields has the better ecological restoration function than the hard lake bank.
