地表水COD浓度灰色预测的GPPM(1)模型

A GPPM(1) FOR GREY PREDICTION ON COD CONCENTRATION OF SURFACE WATER

根据地表水中 COD浓度的时序数据 ,建立了 GPPM(1)预测模型。结果表明 GPPM(1)模型的预测精度优于常规灰色 GM(1,1)模型 ,它为环境系统的拟合、预测和决策提供了新的方法途径。

The basis of the COD time-series date of the surface water,GPPM(1) model has been established.The result shows that much better prediction precision has been gained compared with GM(1,1).It gives a new way to fitting,predicting and decision-marking of environmental system.
