| 摘 要： | 本文对鄱阳湖及五大支流水质监测数据进行统计分析,以图表形式揭示了鄱阳湖及其五大支流CODMn时空变化的规律,总结出了鄱阳湖水系CODMn变化的主要两个特点：①CODMn呈季节性变化;②流经城市地段后,水体CODMn值将升高。通过对CODMn与水质参数的相关性分析,从地表径流、城市生活污水及工业点源、水土流失面源等方面的影响解释了上述特点。

| Abstract: | In this paper the monitoring hydro-date of Poyang Lake and its five branches are collected and analyzed.The CODMn Level of the Poyang Lake Water System are calculated and illustrated in diagrams.The results show that the principals of the spatial-temporal CODMn level changes in the Poyang Lake Water System.Also,two obvious characteristics of CODMn level are found out：①the CODMn level showed seasonal variation;②the CODMn level of water after flowing through the city would rise.And the phenomena are explained in detail in this paper from multiple aspects such as surface runoff,municipal sewage and industri-al point pollution,soil and water losses and etc,based on the relationship analysis between CODMn and water quality parameters. |
