摘要
通过对重庆主城区江段2010年寸滩和北碚断面水质监测数据的统计和分析,对悬浮泥沙含量与总磷浓度的相关性研究。结果表明,监测断面的泥沙含量变化与总磷浓度整体变化趋势相近,呈现出明显的季节变化特征,污染物TP的浑样浓度与清样浓度和含沙量呈线性相关关系,含沙量的变化对TP浓度有一定的影响。
Through statistical analysis on water quality monitoring data of Cuntan and Beibei sections monitored in 2010,this paper studies the correlation between suspended sand and TP.The results show that the content variations of sand and TP are similar in trend on the whole,with significant seasonal features;the content of sand is linearly related to the concentration of muddy samples and clean samples of pollutant TP,and the change of sediment concentration has certain effect on TP concentration.
