| 景观格局与社会经济发展间耦合协调程度对于区域生态安全和可持续发展具有重要意义。以长江流域的南京市为例，借助 ENVI、ArcGIS、Fragstats 与 SPSS 等平台及土地利用和社会经济数据，分析了南京市 2009~2019年间景观格局演变规律及其与社会经济发展之间的耦合协调水平及动态特征。研究表明：（1）2009~2019年间南京市景观结构变化显著，耕地、林地和草地景观面积呈下降趋势，耕地由 385 295.31 hm2 减至352 108.58 hm2，景观类型动态度为 -1.46%；建设用地景观面积显著增加，由 115 489.92 hm2 增至 173 072.81hm2，景观类型动态度为 7.47%；（2）景观空间聚集度和异质性整体呈上升趋势，土地景观类型逐渐由占优势的大斑块所控制，由分散逐渐转为聚合；（3）南京市景观格局和社会经济发展耦合协调程度由 2009 年的 0.378 0变化为 2019 的 0.596 6，呈上升趋势。耦合质量在提升，但相对发展度不平稳，由 2009 年的社会经济发展滞后型转为景观格局变化滞后型。因此，进一步促进二者的协同提升是保持高质量耦合协调的前提。 |

| The coupling coordination between landscape pattern and socio-economic development is significant for regional ecologicalsecurity and sustainable development. Taking Nanjing city along the Yangtzi River as an example，softwares such as ENVI，ArcGIS，Fragstats，SPSS，as well as land use and socio-economic data are used to analyze its evolution pattern of landscape pattern andthe level as well as dynamic characteristics of coupling coordination between the evolution of landscape pattern and socio-economicdevelopment from 2009 to 2019. The results showed that (1) the landscape structure of Nanjing city changed significantly from 2009to 2019 as the area of cultivated land，forest and bare land decreased from 385 295.31 hm2 to 352 108.58 hm2，and the dynamicvariation of landscape type was -1.46%. The area of construction land increased significantly from 115 489.92 hm2 to 173 072.81 hm2，and the dynamic variation of landscape type was 7.47%. (2) the overall spatial aggregation and heterogeneity of the landscape showedan upward trend，and the landscape types are gradually occupied by dominant large patches and gradually shifting from dispersionto aggregation. (3) The coupling coordination degree of landscape pattern and socio-economic development in Nanjing changed from0.378 0 in 2009 to 0.596 6 in 2019，showing an increasing trend. The coupling quality is improving，but the relative development degree of coupling is not stable. Specifically，the coupling coordination type changes from the social and economic lag type in 2009 tothe landscape pattern lag type. Therefore，strengthening the synergistic improvement of both is a prerequisite for maintaining highquality synchronous coordination. |
