| 摘 要： | 为了刻画鄱阳湖生态经济区城镇空间结构的特征,运用分形方法,从城镇空间分布的向心性、均衡性和城市要素的相关性3个方面,测算了描述空间结构分形特征的集聚维数、网格维数和关联维数,根据3个维数的地理意义分析了鄱阳湖生态经济区城镇空间结构的分形特征,并提出了强化中心、轴线发展、圈层优化的发展战略.

| Abstract: | Commencing with the application of fractal theory,the article tries to find the rule of spatial structure in Poyang Lake Ecological Economic Zone.Based on the fractal theory,the article calculates aggregation dimension,grid dimension and spatial correlation dimension of the spatial structure,and finds out that the spatial structure has the fractal properties,so it is concluded that fractal theory can fit to calculate and analyze the spatial structure of Poyang Lake Ecological Economic Zone.According to the results of calculation and analysis,the conclusions that spatial structure of urban system in Poyang Lake Ecological Economic Zone presents distinct convergences character are also drawn.Furthermore,development strategy of Poyang Lake Ecological Economic Zone are put forward,such as to strengthen the central city,to develop along the axis,and to optimize the ring structure. |
