基于物元分析的典型城市选取研究

Research of Typical City Selection based on Matter Element Analysis

本文利用物元分析法,对我国44个公路主枢纽城市进行典型性分析,提出了基于物元可拓的城市典型性评价模型。选取限额以上批发零售贸易业商品销售总额、固定资产投资总额、货物周转量、旅客周转量、年末总人口、市辖区实有城市道路面积、公路通车里程这7个评价指标,将城市的典型性分为很好、好、中、差等4个等级。通过确定待评物元,建立节域物元矩阵和经典域物元矩阵,计算各评价指标权重和综合关联隶属度,得出被评价城市的典型性等级,并通过实例模拟了模型的应用。

This paper applies the matter element analysis theory in studying the typicality of 44 highway hub city of China and raises the asses model of city typical.the paper select such seven assesment factors as Tota sales of enterprises above designated size in wholesale and retail trade by category of main commodities, gross fixed asset formation, volume of freight,volume of passenger, total population by the year-end, the urban road construction of municipal districts,length of highways on operation to rate citys into four degrees as very good,good,medium and error.the assesment process includ confirming matter element to be assede,constructing section field matter element matrix and classical field matter element matrix and counting weight of assesment factors and comprehensive correlative membership Function,with this process it obtains the typical rank of assesed citys.this paper simulates the application of the model with example.
