生态围隔及沉水植物对东湖水质的净化效果研究

Study on the Purification Effect of Ecological Enclosure and Submerged Plants on Water Quality in East Lake

2020年5月至2020年7月在武汉东湖水域采用围隔实验,对东湖水质进行修复,分析试验前后围隔内外水质因子的变化。结果显示,生态围隔内部水质状况优于围隔外部水质状况。试验期内,围隔内部的水体透明度平均为1.2 m,叶绿素a浓度下降7倍,表明围隔试验及沉水植物的种植对水环境的稳定和改善有明显作用。

From May 2020 to July 2020,the containment experiment was used in the waters of Wuhan East Lake to restore the water quality of East Lake and analyze the changes of water quality factors inside and outside the fence before and after the test.The results showed that the water quality inside the ecological enclosure was better than that outside the enclosure.During the test period,the average transparency of the water body inside the enclosure was 1.2 m,and the chlorophyll concentration decreased by 7 times,indicating that the enclosure test and the planting of submerged plants had obvious effects on the stability and improvement of the water environment.
