Abstract: Urbanization is an integrated social, economic and cultural development process. At present, single appraisal indicator which is frequently used to characterize the urbanization level only can partly show the urbanization development level from some aspects, but not reflect the connotation of urbanization. With the case study of thirteen municipalities in Jiangsu Province, an indicator system for evaluating urbanization level was put forward to mirror the district's distinction of Jiangsu's urbanization level more genuinely, including four aspects, such as economic, spatial, population, living mode and living quality. The result shows that the urbanization of Jiangsu Province is divided into five levels,which are ranked from high to low, Nanjing,Wuxi and Suzhou; Changzhou and Zhenjiang; Yangzhou, Nantong and Taizhou; Xuzhou,Yancheng, Lianyungang; Huai'an and Suqian. The district's distinction of urbanization level is evident with the urbanization level descending from south to north and a decline tendency of urbanization level also founded to some extent from east to west.

Key words: urbanization, measurement, fuzzy subordination degree, Jiangsu Province
