摘　　要：湖域地区日益城市化并进而演化为复杂的环湖城市群空间网络化现象,已成为世界性的一个普遍趋势。以环鄱阳湖城市群为例,运用城市规模分布的结构分析方法和非参数检验对其城市规模演变特征与规律进行深入揭示。研究表明:①环湖城市群首位城市影响较大,中间城市出现严重断层现象,中小城市数量多且处于较低水平发展,区域经济发展水平相对落后。②环湖区整体城市化水平得到较快发展,中小城市晋升为大城市速度加快,首位城市与其他城市间差距呈现缩小趋势,但短期内各规模城市之间转型比较困难,首位城市依然占主导地位。③城市规模分布接近Zipf的理想分布状态,具有比较明显的分形特征,同时能较好拟合β>1时的双帕累托对数正态分布曲线,各个规模等级城市数量比例较合理。Firstly, the study has analyzed the evolution characteristics and law of the city size distribution of urban agglomeration around Poyang Lake by a structure analysis and nonparametric test. On the one hand, the result shows that the primary city plays an important role in a size distribution, and middle-size cities appear a serious fault phenomenon, and a number of small and medium-sized cities are at a relatively low developing leyel with an under-developing regional economic level. One the other hand, the result shows that the overall urbanization level is high because the changing speed is rapid from the small and medium-sized cities promoting to the bigger cities, and the gap between the primary city and other cities is decreasing recently, but in a short-term the structural transition in the urban agglomeration is difficult for that the primary city will still prevail for a long time. In addition, the city size distribution abide by an ideal Zipf, s law with a more obvious fractal characteristics, and it can be fitted by a double Pareto curve when β〉1 because the proportion of every size-cities is reasonable with a normal fulfillment of different rank of cities.
