【摘要】：应用ArcGIS空间分析和可达性评价模型,结合SPSS、Matlab等软件,以鄱阳湖生态经济区为研究区域,选取1998年、2008年及2020规划年为时间断面,用栅格法测算交通可达性,分析可达性格局空间演变特征。根据城市质量和时间距离,构建经济联系评价模型,回归分析预测2020年城市质量。对区域内经济总量空间集聚进行分析,并根据三个时间段的最大经济联系格局演变,分析城市间经济辐射范围和城市隶属关系变化。结果发现:区域内可达性改善明显,城市间可达性差距缩小,到2020年全区可基本实现一日交流;区域内经济总量集聚明显,且处于极化状态;由于鄱阳湖湖体的阻隔,区域内形成以南昌、九江、景德镇三大经济中心地,其他为隶属城市的经济联系格局;建议发展南昌至贵溪尤其是东乡至鹰潭段的交通,使鹰潭成为区内第四个经济中心地,实现全区均衡发展。
[Abstract]:Using ArcGIS spatial analysis and accessibility evaluation model, combined with SPSS Matlab and other software, taking Poyang Lake Ecological Economic Zone as the study area, selecting the planning years of 1998, 2008 and 2020 as time section, using grid method to calculate the accessibility of traffic. The spatial evolution characteristics of reachability pattern are analyzed. According to the urban quality and time distance, the economic relation evaluation model is constructed, and the urban quality in 2020 is predicted by regression analysis. The spatial agglomeration of regional total economic volume is analyzed, and according to the evolution of the maximum economic relation pattern in three time periods, the change of economic radiation range and urban subordinate relationship between cities is analyzed. The results show that the accessibility improvement in the region is obvious, the gap between cities is narrowed, the whole region can basically realize a day of communication by 2020; the total economic volume in the region is obviously concentrated and in a polarized state; due to the blocking of the Poyang Lake body, The three major economic centers of Nanchang, Jiujiang and Jingdezhen are formed in the region, and the other is the economic linkage pattern attached to the city. It is suggested that the traffic between Nanchang and Guixi, especially between Dongxiang and Yingtan, should be developed, so that Yingtan will become the fourth economic center in the region. Realize the balanced development of the whole region.
