本文选取安昌河绵阳段6个断面，研究其水体中总有机碳（TOC）、化学需氧量（CODCr ）、生化需氧量（BOD5）和溶解氧（ DO）之间的内在联系与相关性.结果表明 TOC 与 CODCr、BOD 呈线性相关性，其中CODCr ＝2.406TOC -34.186，r ＝0.78，在 BOD5和 TOC 相关性分析中，将各采样点的 BOD5和 TOC 值进行一元线性回归可得出0.786＜ r ＜0.949，说明 BOD5和 TOC 之间存在显著的线性相关性；CODCr与 BOD5之间同样存在着线性相关性，但相关性不显著；DO 和 TOC、CODCr、BOD5之间存在着负相关关系.通过对四个指标的相关性分析，建立各指标之间的相互关系模型来探讨不同指标间替代的可能性.本研究结果对环保部门进行污染治理和环境管理的科学决策具有重要意义.

Based on six sections of Mianyang Anchang River,the study was conducted to find out the internal relation and correlation among TOC、CODCr、BOD5 and DO. The results indicate that TOC and CODCr ,as well as BOD5 ,are with certain linear correlation,precisely expressed by the equation:CODCr = 2. 406TOC - 34. 186 (r = 0. 78). In the related analysis that was carried on BOD5 and TOC,using the linear regression model to eval-uate some chosen samples,the result shows:0. 786 < r < 0. 949,which means that there exists some significant linear correlation. So do CODCr and BOD5 ,but the relation is not notable. They all,DO、TOC、CODCr and BOD5 , are within the negative correlation. Through the related analysis on the given indexes,different models can be es-tablished to study the possibility that one can replace another. Thus,some conclusions will be significant for the environmental departments to make scientific decisions relating to pollution regulation and environmental manage-ment.
