摘要
以洱海流域北部上游东湖片区库塘湿地中水生植物为研究对象,选取5种主要水生植物,寻求净化湿地水质的最佳植物组合。结果表明:东湖片区库塘湿地水体总磷、总氮、氨氮、化学需氧量分别为0.09~0.23、0.80~3.28、0.18~0.89、12.00~37.00 mg/L,总体符合《地表水环境质量标准》(GB 3838—2002)中Ⅳ类要求;综合比较发现,植物组合群落生物量和碳氮磷累积效应优于单一植物;植物组合对水体碳氮磷具有一定的吸收净化作用。
Taking the aquatic plants in the East Lake Area reservoir wetlands of the northern upper reaches of the Erhai River Basin as the research object,five main aquatic plants were selected to seek the best plant combination for purifying wetland water quality.The results showed that the total phosphorus,total nitrogen,ammonia nitrogen and chemical oxygen demand of the reservoir water in the East Lake Area reservoir wetlands were 0.09-0.23,0.80-3.28,0.18-0.89,and 12.00-37.00 mg/L,respectively,which overall met the ClassⅣrequirements of“Environmental quality standards for surface water”(GB 3838-2002).Through comprehensive comparison,it was found that the biomass and carbon,nitrogen,and phosphorus accumulation effects of plant combination communities were superior to those of single plants.Plant combinations had a certain absorption and purification effect on carbon,nitrogen,and phosphorus in water.
