摘　　要：针对太湖贡湖入湖污染负荷高、蓝藻堆积、退渔还湖区基底稳定性差、沉水植被规模化恢复工程技术成熟度低、修复初期生态系统自稳定性差等问题,在滨湖区域地表径流、河道和河口污染拦截与水质净化、生态岸堤构建和生境改善、规模化水生植被重建与生态调控等方面开展了技术研究及综合示范。贡湖湾综合示范区2.32 km2内水体透明度>100 cm,TN<1.5 mg/L,TP<0.1 mg/L,水生植物覆盖度>50%,生物多样性显著提高,实现了“湖水清、生物多、景观美”目标。High pollution load of Gonghu Lake in Taihu Lake、Cyanobacteria accumulation、Poor basement stability in the area of returning fishing to Lake、the technology maturity of large-scale restoration of submerged vegetation is low、Problems such as poor self stability of ecosystem in the early stage of restoration,Surface runoff in lakeside area、river and estuary pollution interception and water purification、Ecological embankment construction and habitat improvement、technical research and comprehensive demonstration have been carried out in large-scale aquatic vegetation reconstruction and ecological regulation.The transparency of water body in 2.32 km2 of gonghuwan comprehensive demonstration area is more than 100 cm、TN<1.5 mg/L,TP<0.1 mg/L,aquatic plant coverage>50%,significant increase in biodiversity.It has achieved the goal of“clear lake,abundant biology and beautiful landscape”.
