摘要
Abstract
The model is built to predict industrial wastewater discharge in Tieling City from 2010 to 2015. According to the characteristics of the data series about industrial wastewater discharge, the GM( 1 , 1 ) model of gray system is employed to build the model for predicting the amounts of Tieling City's industrial wastewater discharge, and the prediction model is modified by using GM ( 1, 1 ) residual model. Comparing the real data series of Tieling City's industrial wastewater discharge from 1999 to 2007 with the predicting data, the errors between real values and the prediction ones are relative small. The experimental results show that the model established by GM( 1,1 )is availability and more accuracy. The model can be used to provide scientific basis for Tieling City's economic development and the water pollution control.关键词
