摘    要:人口预测是土地利用总体规划修编需要解决的重要问题.根据1991-2011年哈尔滨市人口发展的最新统计资料,建立了带有弱化算子的灰色增量模型,对2012-2030年哈市人口发展趋势进行预测研究,预测2030年哈市人口达到1111.81万人,且总人口增长率呈逐年下降的趋势.此外,通过与普通灰色增量模型进行了对比,反映了带有弱化算子的灰色增量模型预测更精确,更有益于区域土地利用总体规划的制定.

关 键 词:灰色增量模型  弱化算子  人口预测

Abstract:The population prediction is an important problem which needs to be solved in land use planning.According to the latest statistical data of Harbin's population development from 1991 to 2011,the grey increment model with the weakening operator is to be established.Based on this model,the prediction of Harbin's population will reach 11.1181 million by 2030,and the rate of its growth shows a downward trend year by year.Compared with other models,the improved grey increment model's prediction is more accurate. Therefore it will benefit regional land-use general planning more.
Keywords:grey increment model  weakening operator  population prediction
