Based on the CA-Markov model, the land use pattern of the basin in 2030 was stimulated, and the future ecological carrying capacity of the watershed was predicted. The results showed that the settlement and water area of the upper reaches of Luanhe River Basin grew rapidly, and the conversion of forest and grassland was active. The grassland area was mostly transferred out, but it was still the dominant land class in the basin. With the active conversion of land use types, the ecological carrying capacity of the river basin generally showed a trend of “first decreasing and then increasing”. The forecast results showed that the ecological carrying capacity of the basin was predicted to increase from 1 844 795 ghm2 to 2 032 204 ghm2 between 2020 and 2030, an increase of 10.16%, and the cantribution of water area to the ecological carrying capacity of the basin was outstanding. The overall pattern of ecological carrying capacity in the upper reaches of Luanhe River Basin was characterized by high in the northwest and low in the southeast, and the internal units showed a trend of patch aggregation in space with time.

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.
