摘　　要：太湖湖滨带湿地作为湖泊的天然屏障,在污染物截留净化、抑藻等生态系统功能维持方面发挥着巨大作用。?跟英文摘要不匹配,是否中间缺少一句话,为此,在分析太湖湖滨带湿地变迁和退化成因的基础之上,提出了湖滨带湿地的恢复策略。在太湖东部湖区采用保育的方式,实现湖滨带湿地自然恢复;在太湖西岸宜兴市东部临湖地区建立30 km2人工湿地,削减入湖河流氮磷污染;在太湖西岸、马山东岸和贡湖湾北岸的重要湖滨带重建98 km的自然湿地,并通过蓝藻打捞等方式降低蓝藻水华对湖滨带湿地产生的不利影响,逐渐恢复太湖湖滨带湿地生态系统,从而减轻太湖湖体蓝藻水华暴发规模,提升太湖水环境质量。As a natural barrier of Lake Taihu,the lakeside belt wetlands play important roles in various ecological functions,such as the interception and purification of nitrogen and phosphorus pollutants,the inhibition of cyanobacterial bloom.However,it has been damaged gradually because of anthropogenic activities.Therefore,by investigating the causes of changes and degradation of lakeside belt wetlands,approaches were proposed for the restoration of lakeside belt wetlands.First of all,conservation methods should be implemented in the eastern Lake Taihu area to achieve natural restoration of lakeside wetlands.One effective way to reduce pollutants load into Lake Taihu is to build 30 km2 of constructed wetlands in the eastern part of Yixing City near Lake Taihu.In addition,it is necessary to restore important natural lakeside belt wetlands of 98 km on lake shores such as the west shore of Lake Taihu,the east shore of Mashan and the north shore of Gonghu Bay of North part lakesides of Lake Taihu.Furthermore,methods,such as should be taken by cyanobacteria salvage to reduce the adverse effects of cyanobacterial bloom on wetlands so that the water ecosystem can be restored gradually in Lake Taihu.The functions of the lakeside belt wetlands on ecological services are optimized to effectively control cyanobacterial bloom and to promote water quality in Lake Taihu.
