Abstract: In order to analyze the influence of major function-oriented zone strategy on urbanization in less developed areas, this paper used 3S Technology, Entropy Weight Method and Pielous Index comprehensively to study on the level and coordination of urbanization in Jiangxi Province, then the problems in urbanization were discussed under the background of major function-oriented zone planning. The following conclusions were drawn. 1) Urbanization process in Jiangxi Province can be divided into two stages: the stage of unbalanced development (2000-2010) and the stage of balanced development (2010-2015), and the most uncoordinated urbanization happened in 2000. 2) The resident population continued to gather in key development zones, while that of restricted development zones were still increasing. The migrant workers mainly flowed to the optimization development zones outside Jiangxi Province, which was contrary to the original intention of the major function-oriented zone planning. 3) In key development zones, the per capita urban construction land area had reached 137.93 m2, and the shortage of population agglomeration was the dominant factor for the uncoordinated urbanization. Therefore, in the area of rapid urbanization, it is necessary to accelerate the establishment of regulations, which relating to the size of urban population and the scale of land use. 4) Local urbanization is the main form of population urbanization, so there will be two pressures in the restricted development zones, one is the transfer of agricultural population, the other is the restriction for large-scale industrialization and urbanization development.
