摘　　要：以环鄱阳湖城市群为研究对象,建立土地城市化的多因素综合评价指标体系,采用均方差权值法对土地城市化水平进行测度,分析2001-2013年环鄱阳湖城市群土地城市化进程的时序和空间特征。研究表明:环鄱阳湖城市群土地城市化综合水平在时间序列上呈现整体逐年上升的趋势;5个城市的土地城市化水平均有显著提升,但市际发展水平很不平衡,土地城市化指数变化幅度和排名的空间差异明显;土地城市化水平呈现"一高一次三低"的格局,中心城市南昌的土地城市化水平最高,九江次之,上饶、鹰潭和景德镇处于相对边缘的位置,位列后三位;土地城市化水平是受经济社会因素和城市等级等多个因素综合影响的结果。In this study, we take urban agglomeration surrounding Poyang Lake area as the research object to analyze the land urbanization and its temporal and spatial characteristics from 2001 to 2013, by establishing the comprehensive evaluation system of land urbanization multifactor and using mean variance weighting method on land urbanization level measurement. The study shows that： The comprehensive level of land urbanization in urban agglomeration surrounding Poyang Lake area has presented an overall increasing trend in temporal series. The land urbanization level in five cities had significantly improved, but the development level is very uneven within the area. The land urbanization index changes in the magnitude obviously as well as the spatial rankings differences. The land urbanization presents ＂a high, a mean and three lows＂ pattern, the highest level of land urbanization shows in the central city of Nanchang, followed by Jiujiang, while the last three are Shangrao, Yingtan and Jingdezhen. The level of land urbanization is affected by many factors, which include the economic and social factors, urban ranking and many other factors.
