| 景观格局变化与社会经济发展之间耦合协调对保护流域生态安全和实现可持续发展具有重要意义。以长江流域南京市为例，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年景观格局演化特征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385295.31 hm2减至352108.58 hm2，景观类型动态度为-1.46%；建设用地景观面积显著增加，由115489.92 hm2增至173072.81 hm2，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0.3780变化为2019的0.5966，呈上升趋势。耦合质量在提升，但耦合相对发展度不平稳，由2009年的社会经济发展滞后转为景观格局变化滞后类型。因此，加强二者的协同提升是保持高质量同步协调的前提。 |

| The coupling coordination between landscape pattern changes and socio-economic development is of great significance for protecting ecological security and achieving sustainable development in the River Basin. Based on platforms such as ENVI, ArcGIS, Fragstats, SPSS, as well as land use and socio-economic data,taking Nanjing City in the Yangtze River basin as an example to analyze the level of coupling and coordination between the evolution of landscape pattern and socio-economic development from 2009 to 2019.The results showed that :(1) the landscape structure of Nanjing city changed significantly from 2009 to 2019, the landscape area of cultivated land, forest land and bare land decreased from 385295.31 hm2 to 352108.58 hm2, and the dynamic attitude of landscape type was -1.46%. The landscape area of construction land increased significantly from 115489.92 hm2 to 173072.81 hm2, and the dynamic attitude of landscape type was 7.47%. (2) the overall trend of landscape spatial aggregation and heterogeneity is on the rise, with land landscape types gradually controlled by dominant large patches and gradually shifting from dispersion to aggregation. (3) The coupling coordination degree of landscape pattern and socio-economic development in Nanjing changed from 0.3780 in 2009 to 0.5966 in 2019, showing an increasing trend.The coupling quality is improving, but the relative development degree of coupling is not stable, which changes from the social and economic lag in 2009 to the development lag type of landscape pattern change. Therefore, strengthening the synergistic improvement of both is a prerequisite for maintaining high-quality synchronous coordination. |
