摘要
城市化与生态系统服务价值存在相互耦合的关系,本研究基于2000-2018年黄河三角洲社会经济和土地利用数据,运用熵权法、耦合协调模型来测定黄河三角洲2000-2018年城市化与生态系统服务价值的耦合协调关系。结果表明,(1)黄河三角洲2000-2018年城市化综合水平呈“V”型变化趋势,人口、经济和空间社会化水平总体呈上升趋势。(2)黄河三角洲2000-2018年生态系统服务价值呈上升趋势,增幅为19.19%,表明研究期间黄河三角洲的生态系统服务价值有明显提升。(3)黄河三角洲2000-2018年耦合度和耦合协调度呈上升趋势,耦合度协调度等级从2008年的轻度失调上升至2018年达到优质协调。
There is a coupling relationship between urbanization and ecosystem service value.Based on the socio-economic and land use data of the Yellow River Delta from 2000 to 2018,the entropy weight method and the coupling coordination model are used to measure the urbanization and ecosystem services of the Yellow River Delta from 2000 to 2018.The value of the coupling coordination relationship.The results show that,(1)the comprehensive level of urbanization in the Yellow River Delta from 2000 to 2018 showed a V-shaped change trend,and the overall level of population,economic and spatial socialization showed an upward trend.(2)The value of ecosystem services in the Yellow River Delta from 2000 to 2018 showed an upward trend,with an increase of 19.19%,indicating that the value of ecosystem services in the Yellow River Delta increased significantly during the study period.(3)From 2000 to 2018,the coupling degree and coupling coordination degree of the Yellow River Delta showed an upward trend,and the coupling degree coordination degree level rose from a slight imbalance in 2008 to a high-quality c0ordination in 2018.
