Improved Logistic Model and Forecasting the Population of Shanxi

Zhang Li(Department of Mathematics,Jinzhong Teachers College,Jinzhong 030600,China)  
In China at present due to the implementation of family planning,population growth rate is very low,obviously Logistic model for simple linear function has been difficult to accurately predict the future population.To more accurately describe China's future population,this paper obtain a new model:dx/dt=r(x0)ea-bxx,x(0)=x0.And according to a 1990 to 2010 Shanxi demographic data on Shanxi in 2020,2030,2040,2050,the population was predicted.
