| 摘 要： | 将综合水质标识指数依照湖泊富营养化评价的特点进行改进,应用于湖泊营养状态评价中.评价指标选择叶绿素、总磷(TP)、总氢(TN)、化学耗氧量(COD)等质量浓度,透明度,每个指标都分配了权重.将该方法应用于全国27个湖泊的营养状态评价,并与其他评价方法比较.经分析表明,该法评价湖泊营养状态结果合理,计算简便,有推广价值,更适合于我国湖泊的水质管理工作.

| Abstract: | The traditional method was modified and applied to the assessment of the eutrophication of China lakes.Five indicators such as chlorophyll a (Chl.a),total phosphorus (TP),total nitrogen (TN),chemical oxygen demand (COD),and secchi disk depth (SD) were included,and each one was assigned with a weight.The method was validated by the measured data of 27 lakes in China and also compared with the other assessment methods.The results show that the method is easy to calculate but obtains convincing conclusions.The method is a valuable tool for lake management in China. |
