【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。更多还原

【Abstract】 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.更多还原
