As one of the most critical ecological functional areas in China and even the world, Sanjiangyuan National Park’s sustainable development has attracted attention. The integrated evaluation method, the coupling coordination model, and the grey correlation model were employed to uncover the coupling coordination relationship among sub-systems in the human ecosystem of Sangjiangyuan National Park. The results are as follows. First, the sustainable development capacity of the human ecosystem in Sanjiangyuan National Park fluctuated and declined during the study period, with insufficient momentum for sustainable development. Second, from 2005 to 2020, Sanjiangyuan National Park experienced a process of optimization and adjustment from moderately uncoordinated to nearly uncoordinated. At the county scale, the coupling coordination state of the sub-system was consistent with the overall national park. Third, among the four dimensions, the correlation degree of openness to the human ecosystem of Sanjiangyuan National Park was far ahead, followed by harmony, independence, and vulnerability. Our research can provide a reference for the coordinated development of the human ecosystem in other national parks with similar ecological functions around the world. |
