摘要
人口预测是制定区域规划的基础,也是研究人口的增长对区域复合生态经济系统的影响和作用的前提。本文应用费尔哈斯模型建立区域人口预测模型,提出了求解费氏模型参数的三种方法,重点论述了最小二乘法及其应用。通过比较研究,本文提出的求解费氏模型参数的最小二乘法具有实际应用意义。
As the base for designing the regional plan, the populations forecast is also the precondition on the research of the population growth's effect to the regional compound ecological system. The article models the regional populations forecast by asing the model of verhulst, then provides three methods of the parametric solution, in which the method of least square algorithm is mainly discussed. By comparing with others, the method of least square algorithm the article discussed, which is used in the solution to the model of verhulst' s parameters, is of great significance in practical application.
