摘要:

基于突变理论构建生态系统服务价值折旧率模型估算草原生态系统服务净价值,运用生态福祉指数评价牧区居民的生态福祉水平,最后通过耦合协调度模型测量二者的耦合协调度水平及其空间差异性。以内蒙古的17个牧业旗县(市)作为研究区,运用2012—2020年的统计数据进行实证研究,研究表明:1)研究区草原生态系统服务净价值增幅达22.9%。典型草原、荒漠草原和草甸草原地区生态环境均得到了不同程度的改善。2)研究区牧区居民生态福祉呈先降后升趋势。典型草原地区牧区居民生态福祉呈先降后升趋势,而荒漠草原地区和草甸草原地区呈波动上升趋势。3)研究区牧区居民生态福祉与草原生态系统服务净价值耦合协调度明显提升。典型草原地区优质协调发展态势逐渐增强;荒漠草原以轻度失调和良好协调为主;草甸草原地区中的2个旗县(市)的耦合协调关系得到了有效改善。

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.
