Abstract: Combined with the coupling coordination model, the data on Yellow River Basin from 2003 to 2018 was used to calculate coupling degree and coupling coordination degree, and the spatio-temporal evolution of production-living-ecological space was analyzed. The results showed that, in the past 16 years, the coupling degree of production-living-ecological space in the Yellow River Basin increased year by year, and experienced a transition from the antagonistic period to the coordinated coupling period. The coupling coordination degree showed a fluctuating rising trend, and nearly 80% of the regions improved from extreme misalignment to mild misalignment, but the regional differences were not obvious. The coupling coordination degree between every two of the production-living-ecological space was rising at different rates. The growth rate of “living-ecological” coupling coordination degree was less than that of the “production-living” and the “production-ecological” coupling coordination degree.

Key words: Yellow River Basin, production-living-ecological space, coupling coordination degree, spatiotemporal evolution
