Urbanization, driven by rapid economic growth, has resulted in dramatic land use/cover change (LUCC), posing substantial risks to urban ecological security. While constructing networks is a productive strategy for achieving balance between protection and urbanization, the limited research conducted on impacts of LUCC spatial patterns during urbanization poses hindrance scientific construction networks. Therefore, this study focuses Jinan City, an important city situated downstream region Yellow River Basin, China. The utilized simulation approaches, including MSPA, MCR, InVEST model gravity model, investigate analyze City from 2000 2020. A set capturing changes network elements was proposed explore evolutionary characteristics pattern Finally, Geodetector impact mechanism findings indicate that: (1) During last two decades, development witnessed expansion approximately 588.83 km2, proportion also increased, but overall structure distribution are not balanced. (2) Despite areas, escalation resistance significant degradation functional capacity corridors, with decrease 8.37 % number primary corridors. reduced connectivity impeded efficient cycling processes ecosystems. (3) complex interactions cumulative effects led evolution transformation cropland into improved composition network, while encroachment disorderly internal types principal factors causing elements. (4) influenced coupling policies. However, there need government strengthen policy coordination optimize layout better manage conserve This holds potential offer valuable insights references guiding planning, protection, formulation sustainable policies throughout process.
