摘　　要：湖泊富营养化是全球性的生态学问题。长江中下游浅水湖泊群作为我国八大湖泊群之一,近30年来水体富营养化以及生态系统功能退化极为严重,亟待系统性修复。水生植物生态修复技术则是面向富营养化浅水湖泊生态治理的重要技术。然而,选择合适的水生植物恢复种来保证恢复效果以及长期的生态安全与稳定性仍是目前恢复工程中的重要且薄弱环节。结合长江中下游湖泊中水生植物的生长、分布、繁殖、来源及污染耐受性等提出了以乡土物种操控为理念适合该区域湖泊的生态恢复先锋物种建议名录,并依据所筛选的物种特性和淡水生态学相关理论,提出不同的优化组合方案来指导长江中下游不同类型湖泊的水生植物生态恢复。Eutrophication is one of serious ecological problems in the world. As one of eight groups of lakes, lakes in the middle and lower reaches of Yangtze River were in the process of severe eutrophication and degradation of ecosystem function in past thirty years, and needed to restore in the systematic ways. At present, ecological restoration by using aquatic macrophytes becomes an applicable and important technology in the control of shallow lake eutrophication. Meanwhile, selection on suitable species of aquatic macrophytes to achieve the results desired and to ensure long-term eco-safety and -stability is still an essential but weak link in the lake restoration project nowadays. Based on the concept of native species control, the present study proposed a selected and suggested species list for lake eco-restoration in the middle and lower reaches of Yangtze River, according to the growth features, distribution, propagation, species sources and tolerance of aquatic macrophytes inhabiting in this basin. In addition, in accordance with the features of the selected species and theories of freshwater ecology, we put forward several optimized combination schemes of various life-form plants to guide the restoration of lake with different types there.
