摘要
分析了沉水植物对湖泊富营养化水体的净化作用,包括降低氮磷营养负荷、净化多种有机物、改善水体溶解氧和透明度、抑制藻类生长。总结了沉水植物对湖泊富营养化水体的修复技术,包括生态沉床、原水位种植、人工湿地和联合固定化微生物等。以沉水植物为主的水生植物修复技术是治理湖泊富营养化水体的一项重要举措,值得进一步研究探索。
The purification effect of submerged macrophytes on eutrophic water of lake was analyzed,including reducing nitrogen and phosphorus nutrient load,purifying organic matter,improving dissolved oxygen and transparency and inhibiting algae growth.The restoration techniques of submerged macrophytes to eutrophic water body of lake were summarized,including ecological sediment bed,planting of original water level,constructed wetland and combined immobilized microorganism.The restoration of submerged macrophyte-dominated aquatic plant is an important measure to treat the eutrophic water body of the lake,which is worthy of further study.
