摘　　要：根据2014年涪江流域遂宁段桂花和老池两个断面COD_(cr)和BOD_5的监测数据,研究了COD_(cr)和BOD_52者的相关性;通过对比2012年实测BOD_5和计算得出的BOD_5,对线性回归方程进行了验证;并考察了遂宁市城区人类活动对非生物降解物质含量的影响。结果发现:这两个断面的COD_(cr)和BOD_5具有较好的相关性,相关系数分别是0.9658和0.9605,并分别建立了线性回归方程;得出的线性回归方程具有较强实用性和较高准确性的结论;此外还发现了遂宁市城区人类频繁的活动增加了微生物不可降解物质的含量。The correlations of CODcrand BOD5 were researched through the monitoring data of Guihua and Laochi in Suining Section of Fujiang River in 2014;the equations of linear regression were verified by comparing the calculated BOD5 and the measured BOD5 in 2012,and the influence of the Suining city urban human activities to the content of material which is not biodegradable was examined.The results showed that there were better linear correlations between CODcrand BOD5 in two above sections.Their correlation coefficients were 0.9658 and 0.9605 respectively,and the equations of linear regression were established too.The conclusion that the equations of linear regression had better practicability and accuracy was obtained.Meanwhile,the content of material which can not be degraded by microorganism was increased due to the Suining city urban human activities.
