摘　　要：根据数据统计分析发现:近年夏天天气炎热、水温在28~32℃时该河流断面溶解氧浓度出现超标的情况。通过SPSS统计分析软件对该河流A水站断面溶解氧、水温、高锰酸盐指数、氨氮、总磷等主要指标进行相关性分析,揭示该感潮河流溶解氧变化特点,以及主要检测指标之间的相互关系。According to the statistical analysis of the data, it is found that in recent years, the water temperature is 28~32℃ in summer, and the concentration of dissolved oxygen in the river section exceeds the standard. Through the correlation analysis of the main indexes such as dissolved oxygen, water temperature, permanganate index, ammonia nitrogen and total phosphorus in a section of the tidal river by SPSS statistical analysis software, the change characteristics of dissolved oxygen in the Tidal River were revealed,and the correlation between the main detection indicators.
