With the rapid development of urbanization, the disorderly expansion of land use for urban construction has led to increasingly severe spatial dislocations of ecological land and construction land, and the topic of rationally planning the scale of urban land use and controlling urban sprawl from the perspective of ecological security has become a challenge for many countries. This paper considers the Jiaodong Peninsula as the study area. The ecological sources were obtained by integrating the results of an ecological importance assessment and the data on nature reserves, a basic ecological resistance surface was built, and ecological corridors and buffers were identified using a minimum cumulative resistance model. Three development scenarios were designed for 2015–2030 based on future land use simulation (FLUS) model, namely, natural development (ND), core ecological patch protection (CEP) and ecological security pattern restriction (ESPR). The ND scenario followed the land expansion rate from 2005 to 2015; the CEP scenario used the ecological sources as a forbidden conversion area, and the ESPR scenario used the ecological security pattern as a forbidden conversion area. A multiscale evaluation system based on the ecological security index (ESI) and the landscape pattern was established to analyze the three scenarios in detail. The main conclusions were as follows: (1) the area of ecological sources of the Jiaodong Peninsula was 3296.85 km2, and 13 ecological corridors were...
