摘要
通过建模求解了2007年大学生数学建模竞赛A题,用带初值的偏微分方程组建立了带扰动的中国人口增长预测模型,对中国人口增长的中短期和长期趋势做出预测,并进一步导出了其离散模型.最后用计算机进行数值模拟.
This paper gives a detailed analysis of the problem A of the Chinese mathematic modeling competition, firstly,establishing a model of the population prediction with perturbation by using partial differential equations with initial values; secondly, predicting the Chinese medium-term and short and long range population grouth, and at last, deducing its discrete form, and gave the simulative results.
