摘要 本文将地面水质视作灰色系统,对某河段的化学耗氧量(COD),生化耗氧量(BOD_5)用灰色预测模型GM(1,1)进行建模、预测。最大误5.2%,平均误差小于0.2%,模型精度高。建模需要的数据较少,对数据的分布无特殊要求,方法和计算简单,实用价值大,是地面水质预测预报的一种有效方法。 The article takes ground water guality as a grey system. By means of grey forecasting model GM (1, 1), the model establishment and its forecasting, of CGD and BOD_5 in a river segment aro done.The precision of the model is high, with maxium error 5.2% and mean error less than 0.2%. It is an effective method to forecast ground water quality, which needs only fewer data and no special requirements for their distribution as well as easily calculates.
