Method for defining metropolitan area based on regional inter-city flow intensity measurement model
First Claim
1. A method for defining a metropolitan area based on a regional inter-city flow intensity measurement model, comprising:
- Step 1;
determining an urban agglomeration regional range centered with a metropolitan city as a spatial range of the metropolitan area to be defined, identifying a plurality of to-be-measured basic city units in the urban agglomeration regional range, and further determining inter-city flow associated cities;
Step 2;
measuring, according to the inter-city flow associated cities determined in Step 1, itemized regional inter-city flow intensities of each group of the inter-city flow associated cities, wherein, the itemized regional inter-city flow intensities include an economic flow, a passenger flow, a freight flow, a technical flow, and an information flow;
wherein the Step 2 comprises;
Step 2.1;
measuring an inter-city economic flow of the associated cities A_Bi determined in Step 1.4;
acquiring, through city statistical yearbooks and related city data materials of the provinces and cities, non-agricultural population UA, UBi of each city, GDP GA, GBi of each city, and a spatial linear distance DABi between the central city A and each of the associated cities Bi; and
calculating an inter-city economic linkage volumes EABi and corresponding inter-city economic flow intensities EfABi of the associated cities;

Abstract
A method for defining a metropolitan area based on a regional inter-city flow intensity measurement model includes the following steps: 1. determining an urban agglomeration regional range to be measured and inter-city flow associated cities; 2. measuring, according to the determined associated cities, itemized regional inter-city flow intensities of each group of the associated cities; 3. calculating through weighing, according to the itemized regional inter-city flow intensity values, integrated inter-city flow intensities and membership degrees thereof between a central city and other associated cities; 4. recording the above data into an ArcGIS library, and establishing a regional inter-city flow database through association between spatial data and table data. 5. performing four groups of naturally intermittent type clustering analysis on data in the established regional inter-city flow database, and finally determining the range of a metropolitan area in a narrow sense and in a broad sense.
