摘要
为快速解决翠湖湿地沉水植物无法正常生长的问题,2012-2013年对翠湖湿地沉水植物的修复实践和恢复技术作了初步探索。结果表明:影响翠湖湿地沉水植物生长的主要限制性因子为光照强度和植食性鱼类数量;水体浊度偏高影响了沉水植物获取足够的光照强度;在修复性种植时用渔网围栏后沉水植物存活率大大提高;种植沉水植物时兼种浮叶、挺水类植物修复效果较为理想;轮叶黑藻为修复后湿地沉水植物群落的优势物种,具有快速的净化效率,可将轮叶黑藻作为群落主要优势种用于受损湿地沉水植被修复。
In order to solve the problem that submerged plants could not normally survive in Cuihu Wetland, Abstract We explored the methods for rehabilitating the submerged plants in Cuihu Wetland during 2012-2013. Results showed that the main limiting factors for the submerged plants to survive in Cuihu Wetland were the sunlight intensity and the number of herbivorousfi shes. The high water turbidity prevented the submerged plants to get enough light intensity. By using fishing net enclosures, the survival rate of submerged plants was greatly increased; Growing submerged plants together withfl oating-leaved plants and emerged plants as a community could result in a better outcome. Hydrilla verticillata was the dominant species in the plant community after the restoring experiments in 2012, which had a rapid process of water purification. Therefore Hydrilla verticillata can be used as the main dominant species of the plant community to rehabilitate the degraded submerged plants.
