摘　　要：长江入海口受咸淡水影响,盐度变化较大。分别通过高锰酸盐指数法和碱式高锰酸钾法对长江口不同盐度水样的CODMn进行测定,并对两种方法进行比对校正。结果表明,两组数据具有明显的正相关关系;经实际数据检验以及测量值和拟合值之间的统计检验分析得出:两组数据之间没有显著差异,两种方法显著相关。为长江口水体CODMn的监测提供了数据支撑,以解决海上和陆地COD监测之间的数据衔接问题。The salinity of Yangtze River Estuary changes greatly due to the fresh water. CODMnof the Yangtze River Estuary is determined by the methods of acid potassium permanganate and alkaline potassium permanganate,and the statistical test analysis shows that there is a correlation between two groups of data. In addition,this work comes to a conclusion based on the data test and statistical test between the measured value and fitted value that there is no significant difference between the two groups of data,and the two methods are significantly correlated. Which providing a practical basis for the Yangtze River Estuary CODMnmonitoring data and solving the problem of COD testing data of coordination of land and sea.
