中国人口增长模型

hina＇s population growth to the impact of various countries, the population growth forecast is very practical implications for solving the problem, we first thought of Malthus model. The model of the requirements more stringent conditions, which we also used the Logistic model to predict the population, the model of Malthus model of the defects were the appropriate remedy, in reality, there are many factors affecting the population, the population can not be unlimited Growth continue, Logistic Model N said that the introduction of constant natural resources and the environment can bear the biggest population and thus be a Bernoulli equation formula of the initial problems, from the practical effect of view, this formula better meet the actual situation Development, as time increases, population growth is not unlimited, but near a few, this is the largest number of bear. We also made an in-depth information on the study, for data analysis and forecasting, through the observation of a relatively good choice and then fitting model to predict. A fitting method and the use of the results of the initial value problem Bernoulli equation formula to compare the results.
