摘要
溶解氧（ＤＯ）是评价水质和水体自净能力的重要指标；耗氧量（ＣＯＤ）在一定程度上反映了水体有机污染的状况．采用赣州市主要河段水样分析ＤＯ、ＣＯＤ值历年的分析资料及重度分布曲线，分析其时空分布及其变化特征，说明赣州市河段的水质因受污染而下降．
Dissolved Oxygen (DO) is an important index that evaltlates water guality and the water body's capacitg of self - purification, and to some degree Consumed Oxgyen Decrease (COD) veflects the condition of the water body's organism pollution. The article uses the Do,COD analytic data of the past years' water samples of the main river reaehes in the city of Ganzhou and the sag distribution curves, analyses the temporal and spatial distribution and its change features and accounts for the decline of water gualitg of the river reaches in Ganzhou city by Pollution.
