考虑了自然资源、环境条件等因素对人口的增长起着阻滞作用，且随着人口的增加，阻滞作用越来越大。运用数值微分技术对Logistic模型进行参数估计，结合Matlab软件对数据进行了拟合。较好地反映出我国人口的增长趋势，并对2011—2030年人口数量进行了预测。%Considered that the factors of natural resources and environmental conditions plays a blockade on population growth,and the blockade grow with the increase of population,used numerical differentiation technique to estimate the parameters of the Logistic model.The data were fitted better combined with Matlab software,it reflected the growth trend of China population,and predicted the population number of China from 2011 to 2030.
