This study innovatively identified the carrying state and limit of Tibet’s resources and environmental carrying capacity and remedy the deficit in this research field. Here, a new theoretical framework was proposed for exploring Tibet’s resources and environmental carrying capacity based on two perspectives of “growth limit” and “stability of human-Earth relationship system”. On this basis, an ideal growth model that accorded with the “short board” effect was carried out to predict Tibet’s population limitation. Analytical results show that the holistic state of resources and environmental carrying capacity in Tibet was in jeopardy. From 2010 to 2016, Tibet’s carrying state continued to decline, moreover, the negative forces still overwhelmed the positive forces; only the resources support have a spare capacity for population increasing while both capacities of environment and ecology were overloaded. Meanwhile, the human-Earth relationship system was in an unstable stage. Three scenarios that responded to different socioeconomic developments were implemented to predict the population limitation of resources and environmental carrying capacity in Tibet; thus, we argue that Tibet should keep its population size within 4 million around 2025. We think this research will provide scientific advices for sustainable development and resources and environmental conservation in Tibet.
