地表水中氨氮和总氮的相关性分析

为了解地表水中氨氮和总氮之间的相关关系,通过2010年濮阳市6个监测点位地表水的氨氮和总氮的监测数据,分析了氨氮和总氮之间的相关性,结果表明:地表水氨氮和总氮两个监测因子之间的相关关系为冬季最好R为0.9270,春、秋其次R分别为0.8980和0.8695,最后是夏季为0.6780。氨氮和总氮之间的比例系数波动范围较大为0.040～1.138,各不同季节的平均值为0.38。

Correlation Analysis on Ammonia Nitrogen and Total Nitrogen in Surface Water

To understand the correlation between ammonia nitrogen and total nitrogen in surface water, some works were done by investigating the monitoring data of six surface water monitoring points in 2010 Puyang city, the correlation of ammonia nitrogen and total nitrogen was analyzed. The results of correlation between ammonia nitrogen and total nitrogen showed that：the correlation coefficient R was 0.927 0 in winter, which indicated the best correlation; then 0.898 0 and 0.869 5 in spring and autumn; finally, 0.678 0 in summer. Variation range of scale coefficient of ammonia nitrogen and total nitrogen was 0.050~1.138, the average value of four seasons was 0.38.
