GEO-INFO模式下区域经济空间非均衡态量化侧度——重庆市实证研究

Measuring Regional Economical Non-balanced Status Based on GEO-INFO Technology:a Case Study of Chongqing

在地理信息技术体系支持下构建了区域经济空间非均衡态的测算方法体系,以重庆市为例开展了该方法体系的实证研究。区域经济非均衡态表征了区域经济要素的空间非均质特性,本研究结合遥感解译数据和地理信息系统空间分析功能构造了七个区域经济发展状况表征指标并生成了相应空间趋势面模型,应用高维空间数据聚类模型对其进行了数据集成分析。在此基础上定义了区域经济发展度与区域经济空间非均衡度的测算方法,应用这种方法测算了重庆市、重庆市三大经济分区和重庆市全部四十个区、市、县的发展度和非均衡度,得出了重庆市区域经济发展状况尤其是其空间分异状况的基本特征。通过本研究表明,重庆市区域经济出现了两大断裂带:其一为东西断裂带,位于垫江、丰都、武隆西边界;其二为都市圈核心区断裂带,位于渝北、北碚、沙坪坝、江津、巴南、江北各区内部。

This paper presents a new methodology to measure regional economical non-balanced status based on GEOINFO technology, taking Chongqing as an example. This paper tests this methodology at last as well. Regional economical non - balanced status is the basic token of spatial homogeneous trait for regional economical factors, combing with the RS data and GIS spatial analyzing functions, this paper designed seven indicators to express regional economical developing situation, and built seven spatial trend surface models accordingly, an integration analysis based on high -dimensions spatial data cluster model had been made as well. With above basic works this paper defined regional economical developing degree exponential （REDDE） and regional economical non - balanced degree exponential （ RENDE ）, applying this two indicators this paper calculated REDDE and RENDE for all administrative area belong to Chongqing,belping with the cal- culating result this paper had found some basic characteristic for Chongqing＇ s regional economical developing situation. According to this study process, we can make sure that there were two economical break lines in Chongqing.
