中文摘要：

城市化水平的区域差异是自然、社会和经济等因素在漫长的历史过程中综合作用的结果。以2000~2010年为时间研究尺度，江西省10个县级市和70个县为研究区域，运用评价指标体系法以及空间自相关指数等研究方法，结合ArcGIS空间分析工具、GeoDA软件和Spassl6．0等软件对江西省县域城市化发展特征及空间格局进行了综合分析。研究表明：（1）江西省城市化发展处于传统的“广度普及型”城市化向“深度推进型”城市化的转型期；（2）但是大部分县市的城市化水平还偏低，城市化水平有两级分化的演变趋势，存在“南、北高，中间低”．的空间梯级变化格局；（3）全省低城市化水平的地区空间收敛趋势明显，赣北呈现高城市化水平极化趋势，赣中与赣南则是随机化明显。研究结论对推进江西省城市化发展进程有重要的借鉴意义。

英文摘要：

In the 21st century,the urbanization of China,one of the countries in the world which is undergo- ing 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 re- search 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 ur- banization 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 evalua- tion 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 fac- tors 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 Arc- GIS, GeoDA and Spass16.0, and comprehensively analyzed the urbanization development and spatial evolu- tion of 80 Cities and Towns in Jiangxi. The results show that： （1） urbanization development in Jiangxi province was in t
