| Abstract: | The grey prediction model GM(2, 1)for pollution charge was established by applying grey theory, its accurate solving method was given and tested with an example of pollution charge in some place. The results showed that the precision of model GM(2, 1) is higher than the model GM(1, 1)'s. And the condition of applying the model GM(2, 1) was also given in the paper. |
