| After eastern development, Western Development and the Northeast Promote, the government puts forward important strategic decision of central rise. Henan province puts forward"Rise of Central Plains", and makes Central Henan Urban Agglomeration as the Back Stone of"Rise of Central Plains". There are many Researches on The Central Plain Cities, but mostly of them are just simple describing or describing base on simple Quantifying Study. Therefore, thorough research on The Central Plain Cities, seek deep lever Spatial Structure and strategy of spatial distribution have important Theoretical and Practical Significance.This paper application the basic theory of urban geography, GIS, Modern statistics and Computational Geometry technical method, makes deep lever research on the Central Henan Urban Agglomeration. It put forward the strategy of the development spatial distribution based on the research.The main research contents of this paper are described as followings:(1)On the basic of analysis the Present Status and problems of the Central Henan Urban Agglomeration. It selects economy, social indicators of the Central Henan Urban Agglomeration, Application of Principal Component Analysis for the Comprehensive Strength of the Central Henan Urban Agglomeration.(2)According to the Comprehensive Strength of towns, Application Voronoi organise Spatial Data, analysis the Hierarchical System of the Central Henan Urban Agglomeration. Obtain 14 first Local Center city as followings: Zhengzhou, Xinxiang, Luoyang, Pingdingshan, Kaifeng, Xuchang, Luohe, Jiaozuo, Jiyuan, Gongyi, Yuzhou, Changyuan, Qixian,Luanchuan; 3 second Local Center city as followings: Zhengzhou, Luoyang, Luohe; at last obtain the high-grade city Zhengzhou.(3)Vectorization the borderline, traffic line of each town, and Application ArcObject module of ARCGIS develop program of the shortest time distance, and calculate the shortest time distance between earch tow towns. Application Gravity Model based on the Comprehensive Strength of towns and the shortest time distance calculate Gravity between earch tow towns. At last calculate Gravity Distribution and Potential of 56 towns of the Central Henan Urban Agglomeration.(4)Application Field Intensity Model, Combined with Comprehensive Strength of towns and Transportation Accessibility, Definition the towns of the Central Henan Urban Agglomeration, Application Voronoi get partition space and Attracting Scope. At last analysis these spatial structure characteristics.(5)Based on the spatial structure characteristics ,at the same time, this paper consider the aim of province about the Central Henan Urban Agglomeration, discuss the strategy of the development and spatial distribution of the Central Henan Urban Agglomeration. |
