摘　　要：课题组基于2010年、2015年、2020年和2022年萍乡市城市质量指标和距离指标数据,运用修正后的引力模型测算出2010年、2015年、2020年和2022年萍乡市各县区间的引力值与断裂点,对萍乡市空间格局的演化趋势进行分析。研究表明:萍乡市各区域间的联系普遍较弱,还缺乏影响力明显的中心区域;地区间屏蔽效应逐渐明显,“北高南低”的整体发展趋势进一步加剧;市区结构形成了安源区—湘东区、安源区—芦溪县、安源区—经济开发区组群发展的“三足鼎立”空间格局。建议政府加快推进城市建设,加大城市交通基础设施建设和新兴产业升级的力度,进一步提升城市中心区域在城市空间布局中的促进作用。This article is based on the urban quality index and distance index data of Pingxiang City from 2018 to 2020.Using a modified gravity model,the gravity values and breakpoints of all counties and districts of Pingxiang City in 2018,2019,and 2020 are calculated,and the evolution trend of the spatial pattern of Pingxiang City is analyzed.Research has found that:the connections between different regions in Pingxiang City are generally weak,and Pingxiang City lacks a significant and influential central area;The shielding effect between regions is gradually becoming apparent,and the overall trend of development towards north high and south is further intensifying;The urban structure forms a"three legged"spatial pattern for the development of the Anyuan district Xiangdong district,Anyuan district Luxi county,and Anyuan district Pingxiang economic development zone cluster.Therefore,it is recommended that the government accelerate the urban construction of Pingxiang City,increase the promotion of urban transportation infrastructure construction,and promote the leading role of the central area in urban spatial layout.
