摘　　要：通过分析城市等级结构和空间关联,有助于识别城市体系发展阶段和协作状况,对于指导区域城市协调发展具有重要的意义。以环鄱阳湖区32城市为研究对象,运用"位序-规模"法则分析后发现:2006年环鄱阳湖区中间位序城市较多,人口分布较为均衡,但研究区的2城市指数高达3.698,南昌市的首位优势十分明显;运用"区域经济联系量"分析南昌市区与其它31城市间经济联系隶属度,结果表明研究区内二级城市中九江、抚州隶属度较高,三级城市中星子、湖口、彭泽和浮梁的隶属度较低。因此,为促进环鄱阳湖区城市群的协调发展,应重点加强二级城市的城市化建设,如九江、新余,促进各级城市间的经济协作。By analyzing the hierarchical structure and spatial relationship of cities,we could well recognize the development and collaborative status of urban system,which have important significance to achieve harmony development between all cites in the region.Thus,all 32 cities around Poyang Lake were considered as the research object,and rank-size rule was used to analyze the urban system around Poyang Lake.The result showed that the proportion of middle-rank cities was higher than other rank cities in 2006,and the population distribution in the area around Poyang Lake was in equilibrium.But,the 2-cities primacy index in research area was up to 3.698,which means that the primacy advantage of Nanchang was very obvious.Then,the quantity of economical relation was used to analyze the membership grade of spatial relationship between Nanchang and other 31 cities around Poyang Lake.The result showed that the membership grade of Jiujiang and Fuzhou were higher than other second-class cities,and the membership grade of Xingzi,Hukou,Pengze and Fuliang were lower than other third-class cities.Therefore,in order to promote the urban agglomeration around Poyang Lake developing harmony,some second-class city,such as Jiujiang,Xinyu,should be accelerated in the construction of urbanization.And the economic cooperation between all cities should be enhanced.
