基于水生植物组合的景观水体生态净化修复

Ecological Purification and Restoration of Landscape Water Body Based on Aquatic Plant Combinations

选择凤眼莲、黄菖蒲、芦苇、迷你皇冠、金鱼藻、苦草、青萍、睡莲作为研究对象,设计不同的水生植物组合,测试分析了其对景观水体生态富营养化的净化修复效果。结果表明:不同水生植物组合对景观水体的生态净化修复作用在整体上优于单种植物;在8个处理组合中,F5组水生植物组合(由芦苇、黄菖蒲、迷你皇冠、苦草、睡莲、青萍组成)对景观水体的生态净化修复效果更好,景观效果更佳,且对水体中营养物质的去除效果更好、更稳定。

Water hyacinth,yellow calamus,reed,mini crown,goldfish algae,bitter grass,green duckweed and water lily were used as the research object.The different combinations of aquatic plants were designed,and their purification and restoration effect on the ecological eutrophication of landscape water body were analyzed by experimental test.The results showed that the ecological purification and restoration effect of different hydrophyte combinations was better than that of single plant.In 8 combinations,the landscape water purification and restoration effect of F5 group aquatic plant combination(reed,yellow calamus,mini crown,bitter grass,water lily and green duckweed) was better.The landscape effect was better,and the nutrient removal effect was higher and more stable.
