文章采用层次分析法与GIS技术,评价南昌都市区内各市区县经济发展层次与城镇化水平是否协调一致。首先根据本地区经济发展的基本特点,建立区内各市区县经济评价的指标体系,并采用层次分析法确定各评价指标的权重,进而计算出每个城镇评价单元的经济发展水平的分指数,最后得到其经济发展综合指数与质量等级。利用Arc GIS 10.2软件及各评价单元的质量等级生成南昌都市区经济发展层次评价等级图,然后与该区内城镇化水平图进行对比分析,构建位序差分级图,以便更好地分析评价南昌都市区各市区县城镇化发展水平。研究结果表明,南昌都市区内大多数区县的经济发展层次与城镇化水平并非处于协调发展状态,对此文章提出了合理化建议。
In this paper,analytical hierarchy process( AHP) and the geographic information system( GIS) are used to evaluate the coordination between the economic development and urbanization level in Nanchang metropolitan area. Firstly,the indicator system of economy is established based on the fundamental features of economic development in each district. Secondly,the weight of each indicator is determined by using AHP,and then the economic development subindex in each evaluated unit is calculated. Finally,the comprehensive index and quality level in each district are obtained. The economic development level map is generated according to the quality level of each evaluated unit in Arc GIS 10. 2 environment. By comparing it with the urbanization level of this district,the order difference grade map can be obtained,and it is convenient in evaluating the urbanization development level of a district. The research results show that it is not harmonious between the economic development level and the urbanization level in most of the Nanchang metropolitan area,with that some rational suggestions are proposed in this paper.
