Abstract: Optimizing the spatial development pattern of land is the primary measure to promote the construction of ecological civilization. Based on the analysis of the spatial and temporal evolution law of the ecological-production-living spaces in Jiaodong Peninsula, an ecological-production-living spaces conflict measurement model was constructed based on "risk source-risk receptor-risk effect" to identify the region and intensity of the ecological-production-living spaces conflict. The results showed that: From 2000 to 2015, the area change of ecological-production-living spaces in Jiaodong Peninsula had the characteristics of "one decline, one rise and one stability". The proportion of production space in Jiaodong Peninsula was the highest, followed by living space, the sum of which was about 85%. From 2000 to 2015, the average conflict index of Jiaodong Peninsula showed an increasing trend. The stable and controllable areas were mainly distributed in the nature reserves within the ecological space, and the seriously out-of-control areas were mainly distributed in the ecotone between the ecological space and production space, and that between ecological space and living space. The order of space conflict degree was production space > living space > ecological space. There were also great differences in spatial types and counties that changed with time.
