摘要

摘要: 利用富营养浅水湖泊武汉东湖中所建立的大型实验围隔系统,对沉水植物的水质净化作用作了现场实验研究。重建后的沉水植物可以显著改善水质,水体透明度显著提高,水色降低。在研究期间,水生植物围隔CODCr和BOD5一般分别为20和5mg/L左右;对照围隔和大湖水体则分别约为40和10mg/L。水生植物围隔水体中可检出的有机污染种类也较对照围隔和大湖水体低。实验结果表明恢复以沉水植物为主的水生植被是改善富营养湖泊水质和重建生态系统的有效措施。

Abstract: The effects of the rehabilitation of submerged vegetation on water quality improvement were investigated by using large scale enclosure system which were installed in a hyper eutrophicated lake,Lake Donghu in Wuhan.The results shown that the transparencies in the enclosures with macrophytes were considerably enhanced compared with the control enclosure without macrophytes and the lake water,while the apparent water color was decreased.COD Cr and BOD5 were about 20 and 5 mg/Lrespectively in the macrophyte enclosures,while those of the control enclosure and lake water were at the level of 40 and 10 mg/L.The number of detected organic pollutants isolated from the water body of macrophyte enclosures was also lower than that of the control enclosure and the lake water.It was demonstrated that the water quality could be significantly improved by reconstructing aquatic macrophytes.
