Urbanization, driven by rapid economic growth, has resulted in dramatic land use/cover change (LUCC), posing substantial risks to urban ecological security. While constructing ecological networks is a productive strategy for achieving a balance between ecological protection and urbanization, the limited research conducted on the impacts of LUCC on the spatial patterns of ecological networks during urbanization poses a hindrance to the scientific construction of ecological networks. Therefore, this study focuses on Jinan City, an important city situated in the downstream region of the Yellow River Basin, China. The study utilized simulation approaches, including MSPA, MCR, InVEST model and gravity model, to investigate and analyze the ecological networks of Jinan City from 2000 to 2020. A set of patterns capturing the changes in ecological network elements was proposed to explore the evolutionary characteristics of the spatial pattern of ecological networks. Finally, Geodetector was utilized to investigate the impact mechanism of LUCC on the spatial pattern of ecological networks. The study findings indicate that: (1) During the last two decades, the urban development in Jinan City has witnessed an expansion of approximately 588.83 km2, and the proportion of ecological land has also increased, but the overall structure and spatial distribution of construction and ecological land are not balanced. (2) Despite the expansion of ecological areas, the escalation of ecological resis...
