| 摘 要： | 本文主要应用SPSS软件的箱线图和正态分析的方法,研究2006-2010年淮河干流蚌埠闸上断面的流量、溶解氧、高锰酸盐指数和氨氮等水质指标的变化状况,并对各年的水质指标超标率进行统计分析,通过研究可知,枯水期蚌埠闸流量值远低于丰水期;丰水期水中DO含量低于枯水期;枯水期水中的氨氮含量高于丰水期;各水质指标在各年内均存在非常显著的差异;近两年来,蚌埠闸水质状况已有较大的改善。

| Abstract: | In this paper,we mainly study on water parameters（flow rate,DO,CODMn and NH3-N） of Bengbu Sluice in Huai River in the year of 2006-2010,using Box-Plot and test of normality in the software of SPSS;over standard rate of these five years is also included.We get conclusion that flow rate of Bengbu Sluice in drought period is much lower than in high flow period;DO in high flow period is lower than in drought period;NH3-N in drought period is higher than in high flow period;all parameters have significant difference in these five years.Water quality of Bengbu Sluice has yearly realized a tangible improvement in recent years. |
