备注

以甘肃省各地级市为对象,利用熵权法确定指标权重,通过耦合协调度模型及地理探测器等方法,分析了2009—2018年甘肃省城镇化与生态环境系统耦合协调度的时空动态演变与影响因素。结果显示:(1)甘肃省各市城镇化及生态环境子系统水平均呈上升趋势,80%的城市城镇化水平低于生态环境水平,属于“城镇化滞后”型城市。(2)甘肃省城镇化与生态环境耦合度及耦合协调度呈现波动提升趋势,但增长幅度较小。耦合度整体上处于拮抗阶段和磨合阶段,耦合协调度整体处于中度失调水平,且空间差异较大。(3)各影响因子对研究区耦合协调度的影响存在差异,10年间绝大多数因子对耦合协调度影响力加强。其中人均社会消费品零售总额、人均耕地面积、人均拥有市辖区建成区面积、人均工业废水排放量等指标对耦合协调度影响较大。因此,应根据主要影响因素制定精准发展策略,促进城镇化与生态环境协调发展。
Taking 12 prefecture-level cities in Gansu Province as the research objects, based on entropy weight method and coupling coordination model, we analyzed the coordination degree's space-time dynamic evolution and influencing factors between urbanization and ecological environment in Gansu Province from 2009 to 2018. The results showed that:(1)the level of urbanization and eco-environment subsystems of cities in Gansu Province had been continuously improving, with 80% of urbanization levels being lower than the ecological environment level, and they were classified as ‘lagging urbanization' cities;(2)the coupling degree and coupling coordination degree between urbanization and ecological environment in Gansu Province showed the rising trend of fluctuation, but the growth rate was small; the coupling degree was in the antagonistic stage and the running-in stage as a whole, and the coupling coordination degree was in a moderate imbalance level, and the spatial difference was large;(3)the influence factors had different influences on the coupling coordination degree in the study area, and the influence of most factors on the coupling coordination degree had been strengthened in 10 years, among which the total retail sales of consumer goods per capita, the area of cultivated land per capita, the area of built-up areas per capita of municipal jurisdiction, and the per capita discharge of industrial wastewater had the great influences on the coupling coordination degree. Therefore, a precise development strategy should be formulated according to the main influencing factors to promote the coordinated development of urbanization and the ecological environment.
