- 基于马尔萨斯及Logistic人口模型,本文做了相应改进,根据已有数据确立了我们的人口模型。人口净增长率与人口密度比是简单常数值或者是简单的指数函数,所建立的模型来预测人口总数都是不完备的,所以我们假定人口净增长率是随总人口变化的函数,而这个函数是我们通过数据拟合可以近似得到的,由人口净增长率函数的确立,我们可以以微分方程的形式建立人口模型-Based on the Malthusian and Logistic population model, this article has done a

Finite_difference_method
- 有限差分法 微分方程和积分微分方程数值解的方法。基本思想是把连续的定解区域用有限个离散点构成的网格来代替, 这些离散点称作网格的节点;把连续定解区域上的连续变量的函数用在网格上定义的离散变量函数来近似;把原方程和定解条件中的微商用差商来近似, 积分用积分和来近似,于是原微分方程和定解条件就近似地代之以代数方程组,即有限差分方程组 , 解此方程组就可以得到原问题在离散点上的近似解。然后再利用插值方法便可以从离散解得到定解问题在整个区域上的近似解。 -Finite Difference Me
