摘要: The sustainable development of the Tibetan Plateau is vital for Asia and the entire world, as this region is usually referred to as the Asia Water Tower and the Third Pole. Previous studies have focused on the ecological protection of the Tibetan Plateau, largely ignoring the sustainable development of its cities as the carrier of most people on the Tibetan Plateau. In this study, we optimized the economy-resource-ecological environment (ERE) system of the largest city on the Tibetan Plateau, namely Xining. To this end, we first established a system dynamics model of its ERE system, and highlight local policies such as the Yindajihuang Water Transfer Project. Then, we evaluated the coordination of the ERE system under multiple trade-off scenarios, by developing and applying a ranked weights-based coupling coordination degree (CCD) model. This new CCD model avoids accurate and subjective weighting of multiple criteria, thus being more widely applicable and objective. The evaluation results indicate that the resource subsystem should be more emphasized than the economy subsystem, to avoid severe deterioration of the ERE system. Also, the coordination of Xining's ERE system could be effectively improved by setting highest development priority for the ecological environment subsystem.
