摘要
对各研究水体采样测定pH值、总磷、总氮、COD等水污染指标,并对测得的结果采用单因子评价法进行计算。依据计算所得的污染指数将各湿地污染状况进行比较分析。结果表明,大部分研究对象的污染指数超过设定标准。所研究的这部分水体的污染情况较严重。
The water pollution target PH,Sum N,Sum P and COD is measured.The measured result is calculated with single factor appraisal method.The state of various marsh pollution is compared and analysed according to calculated pollution index.The result indicates that the pollution index of greater part of studied objects surpasses the standard,the studied water body is polluted gravely.
