修正内梅罗污染指数法在水源地环境质量评价中的应用

为了克服内梅罗指数法存在的不足，将公式中的算术平均修改为加权平均。选取溶解氧、总磷、CODcr等10项指标作为评价指标，用修正后的方法对蕉岭县4处水源地进行综合评价，并将评价结果与单因子评价法进行比较。结果表明，改进的内梅罗污染指数法的评价结论比单因子评价法的评价结论更科学、合理和全面的反映综合水质状况。

Application of Improved Nemerow Exponent Method for Evaluation of Environmental Quality of Waterhead Area

To overcome the shortcoming of Nemerow exponent methodm,it had been changed the arithmetic mean in the formula into the weighted average.Based on determination of 10 indexes including Dissolved Oxygen,total phosphorus,CODCr and so on,the environmental quality of four waterhead areas for water in Jiaoling city were assessed integrally adopting the improved Nemerow exponent Method.The assessed results were compared with that of sine factor assessments.It found that the assessment conclusion by improved Nemero...
