Abstract: Rapid urbanization has led to ecosystem fragmentation, conversion, and degradation, posing great threats to natural habitat and biodiversity. The utilization of ecological networks has gained importance in ecological restoration planning to mitigate the negative impacts of urbanization on ecosystems. This study focused on Nanchang City, China, as a case study area to examine the application of integrated ecological networks in 2000, 2010 and 2020. This study analyzed the dynamic characteristics and spatial differences in landscape connectivity, providing evidence-based support for ecological conservation and restoration. The results indicate the following: (1) a decrease in the number of ecological sources and corridors, especially general sources and corridors, along with a decreasing trend in their importance; (2) an increase in ecological barrier points and breakpoints over time, especially in the southeastern region of the study area; and (3) the identification of ecological conservation priority areas, ecological improvement priority areas, and ecological restoration points based on connectivity and dynamic analysis. Multiple priority actions were proposed, which remarkably improved network connectivity and strengthened biodiversity conservation. Our research provides a valuable reference for identifying ecological priorities and developing ecological protection and ecological restoration actions in highly urbanized areas.
