黄河三角洲城市土地利用与生态环境耦合关系

Study on coupling relationship between urban land use and ecological environment in cities of the Yellow River Delta

为了探究城市土地利用与生态环境之间存在的耦合关系,找出促进城市土地利用与生态环境和谐发展的方法,以黄河三角洲区域核心城市东营和滨州为研究区域,利用耦合协调测度模型,对研究区域2002-2016年的土地利用综合指数、生态环境综合指数以及2个系统的耦合协调度进行分析,同时对指标的权重进行敏感性验证。结果表明,2002-2016年东营和滨州的土地利用与生态环境的综合指数均呈现上升趋势,从耦合度和耦合协调度来看,研究区域处于良好耦合阶段,土地利用与生态环境的协调发展经历了从中度失调到良好协调的5个阶段,应用熵值法确定的指标权重合理可靠。研究结果可为东营和滨州的城市管理提供科学依据,也可为同类型城市的研究提供方法和参考。

In order to explore the coupling relationship between urban land use and ecological environment, and promote the harmonious development of land use and ecological environment, the core cities of the Yellow River Delta, Dongying and Binzhou, were selected as the study areas. The coupling coordination measure model was used to analyze the land use comprehensive index, the ecological environment comprehensive index and the coupling coordination degree of the two systems from 2002 to 2016. Meanwhile, sensitivity verification was carried out on the weights of indicators. The results showed that the comprehensive index of land use and ecological environment in Dongying and Binzhou had an upward trend from 2002 to 2016, from the perspective of coupling degree and coupling coordination degree, the research areas were in a good coupling stage, and the coordinated development of land use and ecological environment experienced five stages from moderate imbalanced to well coordinated. The weights of indicators determined by the entropy method was reasonable and reliable. The study not only provide the scientific basis for the management of the two cities, but also provide study the method and reference for other similar cities.
