摘要
对松花江同江断面3年自动监测的数据进行分析,得出该断面溶解氧浓度的影响因子为高锰酸盐指数和氨氮,并分别总结出不同年度、不同水温下的回归方程。多因素相关分析结果显示,高锰酸盐指数、氨氮的含量与水体中的溶解氧浓度呈显著性负相关关系。
According to Tongjiang on-line monitoring in 2007~2009,with correlation analysis,the main factors affected dissolved oxygen were found,which were CODMn and ammonia.Liner regression equations of different years and different temperature were explored.The dissolved oxygen was significant negative correlation with CODMn and ammonia.
