Abstract:

In the 21st century,the urbanization of China,one of the countries in the world which is undergoing the rapid urbanization,is widely regarded as one of the two factors that drive world economic and social development.Consequently,the Chinas urbanization research is now focused by the worlds leading research institutions and researchers.In addition,Chinese government proposed the National Mediumlongterm Plan for Science and Technology Development (2006-2020) in 2005,and the research techniques of the city development were listed into the 11 key areas and priority themes for the first time.The article aims at exploring the urbanization fluctuation rules of spacetime difference in Jiangxi province,which will provide convenient services to the government,demonstrating an important practical significance.In recent years,foreign researches on Chinese urbanization include Chinese dual urbanization,determination of urbanization level,the law of urbanization under the background of the socialist market economic system,and the transition of urban social spatial structure.Chinese scholars also concentrate on comprehensive evaluation of urbanization level,regional difference of urbanization level and its influencing factors.The common methods include clustering analysis,principal component analysis,index system analysis and tins index,etc.In the process of the long history,the regional difference of urbanization level is a result of many factors such as nature,society and economy.The article took the years from 2000-2010 as the study section,and 10 countylevel cities and 70 counties in Jiangxi province as the study area.This study applied research methods such as evaluation index system method and spatial autocorrelation indexes,combined with ArcGIS,GeoDA and Spass160,and comprehensively analyzed the urbanization development and spatial evolution of 80 Cities and Towns in Jiangxi.The results show that：(1) urbanization development in Jiangxi province was in the period of “deeply pushed pattern”;(2) urbanization level of most cities was still low,and presented the evolution trend of polarization and change pattern of “high in south and north,low in middle”;(3) the cities with low urbanization level obviously reflected space convergence trend.High urbanization level in north Jiangxi was polarized,moreover,urbanization level in middle and south Jiangxi trended to be randomly distributed.The research conclusions play an important role in promoting the urbanization process of Jiangxi province
