摘要
通过黑龙滩水库中 7个采样点 ,17个月 2 1个指标的连续采样分析 ,数据显示出水库中水质理化指标 ,在水平分布上无大的差异。垂直分布上DO和CODMn变化较大 ,其浓度是随深度而降低。其余指标在一年的周期内维持在稳定的水平上。除T P外 ,水库中其余指标物在Ⅱ级标准内。T
Based on the monitoring data of water quality of Heilongtan Reservoir in the period of 17 months and at 7 points by 21 indices,the distribution of water quality has been studied.The results show that indexes of water quality are almost no difference in the horizontal.DO and COD Mn vary in the vertical,and their levels decrease with the depth.It is showed that the change of nutrients is not great in the period of a year.But T P is over the relevant standard and the eutrophication is potential.
