摘要
土地利用效益和城市化的耦合关系对于土地紧缺的干旱区内陆河流域绿洲城市的发展至关重要。以武威市凉州区为例,利用耦合协调度模型、灰色关联分析模型等分析其城市土地利用效益与城市化耦合协调发展关系。结果表明:2002—2012年,武威市凉州区土地利用的社会效益、经济效益和生态效益以及人口城市化、经济城市化、社会城市化、空间城市化和生活方式城市化指数均呈现明显的增加趋势。研究区土地利用效益值、城市化指数以及城市土地利用效益和城市化的综合评价指数呈现出线性递增的特征,且土地利用效益值增长速率快于城市化指数。土地利用效益和城市化的耦合协调系数从0.273 6提高至0.907 0,耦合协调状态由中度失调逐渐转为优质协调,耦合协调阶段可分为失调衰退—过渡—协调发展3个时期。城市土地利用效益和城市化发展之间存在相互驱动关系,即土地利用的经济效益对城市化产生的驱动影响较显著,城市化则主要从社会(人口)因素和经济因素两方面对土地利用效益产生驱动影响。研究结果对石羊河流域绿洲城市乃至干旱区绿洲城市的发展有一定的借鉴意义。
It is crucial for the development of oasis cities in arid inland river basin to explore the coupled relationship between land use benefits and urbanization. A case study on the coupling mechanism between urban land use benefits and urbanization was carried out in Liangzhou,Wuwei in the Shiyang River Basin using the coupling harmonious degree model and gray relation analysis model. The results showed that the indexes of social,economic and ecological benefits of land use and population,economic,social,urban space and lifestyle urbanization were all in a significant increase in Liangzhou,Wuwei during the period from 2002 to 2012. There were the linear increments in the indexes of land use benefits,urbanization and comprehensive evaluation,and the growth rate of land use benefits was higher than the urbanization index. The index of coupling mechanism between urban land use benefits and urbanization in the study area was increased from 0. 273 6 to 0. 907 0,the status of coupling mechanism became gradually from a moderate disorder to a good coordination,and the coupling coordination could be divided into 3 stages,i. e. the recession,transition and coordinated development. There was a mutual driving relationship between urban land use benefits and urbanization,a significant positive effect of economic benefits of land use on urbanization,and also a significant positive effect of urbanization on the land use benefits from the aspects of social（ population） and economic factors. The results had a certain referring significance for the development of all the oasis cities in the Shiyang River Basin and even those in arid area.
