摘要
为了解洪泽湖水质状况,对2000年洪泽湖富营养化状态和生态特性的调查结果进行了分析,洪泽湖水中总磷、总氮和高锰酸盐指数年均值超《地表水环境质量标准》(GHZB1-1999)中Ⅱ类水标准,超标倍数分别为12倍、10倍和0.24倍;总磷、总氮、透明度年均值超湖库特定项目V类水标准,洪泽湖处于中-富营养化状态。对洪泽湖生态特性分析表明,由于洪泽湖独特的湖泊形态,"藻型浊水状态"和"泥沙型浊水状态"交替出现,遏制了湖水从高营养盐含量向全面富营养化状态演变,保证了底栖动物的良好生长环境,从而形成了洪泽湖独特的环境生态平衡状态。
The state of eutrophication and ecology of The Lake of Hongze in 2000 was investigated. The result indicated that TN, TP and permanganate index were all beyond the standard of Ⅱ water in Surface Water Environmental Quality Standard (GHZB 1-1999)the times were 12, 10 and 0.24. The annual mean value of TP, TN and diaphaneity were all beyond the V water standard. The Lake of Hongze was on the state of middle- eutrophication. The analysis about the ecology of indicated that the unique state of Lake of Hongze hold back the trend of eutrophication.
