摘要
常规ＧＭ（１，１）是一个指数模型，应用于多样环境系统有一定的局限性。本文根据某地表水中ＣＯＤ浓度的时序数据，建立了ＧＰＭ（１）预测模型。结果表明ＧＰＭ（１）模型优于常规ＧＭ（１，１）模型。它拓宽了ＧＭ（１，１）模型在环境单变量时序系统中的应用范围，为环境系统的拟合、预测和决策提供了新的途径。
The traditional GM(1,1)was an exponential model and it had some limitations when it
was applied to various environmental system.In this paper,on the basis of the CoD log rank date
of the surface water,GPM(1) model has set up,the result shows that GWP(1) is superior to the
traditional GM(1,1) model.This one widens the application scope of GM(1,1) in the field of
environmental single variable log rank system and provides a new way of fitting、prediction and
decision-making of environmental system.
