黄河流域三生空间耦合协调的时空演化分析

Spatio-temporal evolution of coupling coordination of production-living-ecological space in the Yellow River Basin

利用黄河流域2003—2018年相关数据,结合耦合协调模型,测算黄河流域三生空间耦合度及耦合协调度,并进行时空演化分析。结果表明,黄河流域三生空间耦合度逐年上升,经历了从拮抗时期向协调耦合时期的过渡;耦合协调度呈波动上升的趋势,近80%的地区由极度失调改善至轻度失调,但区域差异不明显;三生空间两两之间的耦合协调度不断上升,但“生活-生态”功能耦合协调度增长速度小于“生产-生活”耦合协调度和“生产-生态”耦合协调度。

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 ana⁃lyzed.The results showed that,in the past 16 years,the coupling degree of production-living-ecological space in the Yellow River Ba⁃sin 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 mis⁃alignment,but the regional differences were not obvious.The coupling coordination degree between every two of the production-livingecological 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.
