城市人口系统等维灰数递补动态模型探讨

Research on Gray Dynamic Model with Equal Dimension in the Urban Population System

应用灰色系统等维灰数递补动态预测模型,对桂林市的人口进行了动态预测。通过检验表明,该模型合理,能够为城市政府部门的决策提供科学依据。

The quantity of urban population affects economical and social development of the city directly,the population problem is the key factor restricting the urban development,and therefore,there is important operation significance in researching on the urban population.In this paper the gray number dynamic model with equal dimension in gray system was used to forecast to the population of Guilin.It was proved that this model reasonable,thus it could provide scientific basis of decision-making for the city government.
