摘　　要：本文选用综合污染指数法、改进的内梅罗指数、综合水质标识指数法,对南北河水质状况进行综合分析评价。结果显示:3种不同评价方法均表明南北河水质整体良好,能满足水质功能区Ⅲ类水体的要求,水质整体变化呈好转趋势;3种评价方法水质变化趋势的显著性均有一定差别,但整体水质情况和变化趋势基本一致。3种评价方法对于南北河水质进行综合评价具有重要意义,可以更全面地反映南北河水质的综合状况,有效地弥补单因子评价法的局限性。This article uses the comprehensive pollution index method,improved Nemero index,and comprehensive water quality identification index method to comprehensively analyze and evaluate the water quality status of the North and South rivers.The results show that:All three different evaluation methods indicate that the overall water quality of the North and South rivers is good and can meet the requirements of Class III water bodies in the water quality functional zone.The overall change in water quality shows an improving trend;Although the three evaluation methods have certain differences in the specific evaluation results of water quality categories and the significance of water quality change trends,they are basically consistent with the overall water quality situation and change trends.Three different evaluation methods are of great significance for the comprehensive evaluation of water quality in the North and South rivers,which can more comprehensively and meticulously reflect the comprehensive status of water quality in the North and South rivers,and effectively compensate for the limitations of single factor evaluation methods.
