| Abstract: | In this article, it is used with gray metabolic model to predict the total population, through the prediction analysis, to find the best prediction model. According to projection result, the population will reach 8.126 956 million in 2015 at Zhengzhou, and in 2020 to approximately 8.656 011 million, and by 2023 will reach 8.989 718 million, it shows that the population appears a steady growth trend. |
