摘　　要：恢复沉水植物是受污染水体生态修复与重建的有效措施之一,人工快速大面积恢复沉水植物的方法是关键。选取杭州西湖西进区域茅家埠和浴鹄湾近岸水域,分别采用扦插法、沉栽法和播种法对沉水植物菹草、苦草和黑藻进行种植。研究表明:运用沉栽法种植的菹草存活率比用播种法种植的存活率高71.1%;运用扦插法种植的苦草比沉栽法和播种法的存活率分别高84.3%和87.8%;运用扦插法种植的黑藻比用播种法种植的存活率高69%;3种种植方式下最终的单株植物生物量间无显著差异。The restoration of submerged macrophytes is one of the effective measures to recover the contaminated water ecological system. The planting measure is the most critical approach to restore a large area submerged maerophytes in short time. In this paper, Potamogeton crispus, Vallisneria, and Hydrilla verticillata were planted by cutting, sinking and seeding in shallow zones at Maojiabu and Yuhu sublakes which is the west part of Xizi Lake. The results have shown that the survival rates of P. crispus by sinking is 71.1% higher than seeding; the survival rates of Fallisneria by cutting is 84.3% and 87.8% higher than sinking and seeding; the survival rates of H. verticillata by cutting is 69% higher than seeding. There was no significant difference in the final biomass of plant by three planting patterns.
