Abstract:

Based on the catastrophe theory, a depreciation rate model of ecosystem service value was constructed to estimate the net value of grassland ecosystem services. The ecological well-being index was used to evaluate the ecological well-being level of pastoral residents. A coupling coordination degree model was used to measure the coupling coordination degree between ecosystem service value and the ecological well-being of residents, and further analyses clarified the spatial differences. The research area consisted of 17 counties (cities) in Inner Mongolia where animal husbandry is the main activity. Statistical data from 2012 to 2020 were used for analyses. It was found that: 1) The net value of grassland ecosystem services in the study area increased by 22.9% during the 8 years from 2012 to 2020. The ecological environments of typical grassland, desert grassland, and meadow grassland in Inner Mongolia have been improved to varying degrees. 2) The ecological well-being of pastoral residents in the study area showed a pattern of initially decreasing and then increasing during the 8 years. Specifically, the ecological well-being of residents in the typical grassland area of Inner Mongolia showed a trend of initial decrease and then increase, while those of residents in the desert grassland area and meadow grassland area of Inner Mongolia showed a fluctuating upward trend. 3) The coupling coordination degree between the net value of grassland ecosystem services in the study area and the ecological well-being of residents in pastoral areas significantly increased during the 8-year period. The trend of high-quality coordinated development of typical grassland areas in Inner Mongolia has gradually increased; While trends of mild imbalance and good coordination were detected for the desert steppe. The coupling coordination relationship between the two counties (cities) in the meadow steppe area has effectively improved over time.

Key words: grassland ecosystem service value, ecosystem depreciation rate model, ecological well-being of pastoral residents, coupling coordination degree
