摘要
辽河是辽宁省内的重要河流之一。根据监测资料显示2019年辽河在沈阳境内水质可以达到Ⅲ类水标准,通过皮尔逊相关性检验法对辽河上4个全国重要水质监测断面2019年的汛期水质水量监测资料分析,各种污染物浓度变化存在一定的规律:总氮含量与流量有强相关性,氨氮含量与流量呈现负的弱相关性或负的中等相关性,高锰酸盐指数与流量呈弱相关或中等相关性,总磷含量与流量呈现极弱相关或无相关性。
The Liao River is one of the important rivers in Liaoning Province. According to monitoring data, the water quality of the Liaohe River in Shenyang in 2019 can reach Class Ⅲ water standards. The Pearson correlation test method was used to analyze the water quality and quantity monitoring data of four nationally important water quality monitoring sections on the Liaohe River in 2019 during the flood season. There are certain laws in the changes in the concentration of various pollutants. The total nitrogen content has a strong correlation with the flow rate. The ammonia nitrogen content and the flow rate show a negative weak correlation or a negative medium correlation. The permanganate index is weakly or moderately correlated with flow. The total phosphorus content and the flow rate show very weak or no correlation.
