| 摘 要： | 于2005-2007年调查浏阳河长沙段的COD与DO时空分布特征。结果表明：（1）浏阳河长沙段COD质量浓度季节分布的大小顺序为：冬季〉秋季〉春季〉夏季;在空间分布上,从上段至下段COD质量浓度呈现出小—大—小的变化规律;从COD质量浓度的垂直分布来看,在春夏季,表层与底层COD质量浓度差异不明显,而在秋冬季则表现为表层COD浓度明显大于底层COD浓度;（2）浏阳河长沙段DO含量的季节分布规律为：冬季〉秋季〉春季〉夏季。在空间分布上,DO含量分布从上段至下段的呈大—小—大的变化趋势,基本上与COD的变化情况相反。

| Abstract: | The spatial-temporal distribution characteristics of chemical oxygen demand(COD) and dissolved oxygen(DO) were investigated from 2005 to 2007.The results showed that:(1) The temporal distribution characteristics of COD were:in the winter >in the autumn> in the spring >in the summer;the spatial distribution characteristics of COD were the concentrations increased first then decreased from the upper zone to the down zone.the perpendicuar distribution characteristics of COD were there were not difference in th... |
