Application of remnant GM (1 , 1) to prediction of content of sulfur dioxide in atmosphere

Abstract: By the theory and method of GM (1 , 1)model , the grey remnant equation x (t +1) =-0.107 432e-0.095 872 t +0.123 917 was established to predict SO2 content of atmosphere in Lin'an City .Absolute value of relative error between prediction and observant values was about 0.56 %to 14.51 %, testifying ratio after prediction was 0.280 2 , and small error probability was 1.0 .The results show that the model corresponds more to practicality and attains high precision .Grey model prediction method is easy to use and have common and conductive significance to construct ecological environment in future .
