摘要
运用灰色关联分析方法构建区域产业结构与用水结构之间相互作用的灰色关联度模型及耦合度模型,揭示皖江城市带产业结构与用水结构之间耦合的主要因素,并分析产业结构与用水结构耦合度的时序变化和空间差异。结果表明:皖江城市带产业结构与用水结构之间的关联度基本都在0.5以上,属于中等关联。产业结构与用水结构耦合度表现出明显的阶段性,大致呈倒U形,根据数值变化可以划分为3个阶段:磨合型(2005—2006年)、拮抗型(2007—2009年)、初级协调型和磨合型(2010—2014年)。皖江城市带各城市的耦合协调类型不尽相同:合肥、芜湖属于初级协调型;马鞍山、铜陵属于磨合型;滁州、宣城、池州属于拮抗型;安庆、六安属于失调型。
The grey relational model and coupling degree model of interaction between regional industrial structure and water use structure are constructed by using grey relational analysis method to reveal the main factors of coupling between industrial structure and water use structure in Wanjiang City Belt. Furthermore, the temporal variation and spatial difference of coupling degree between industrial structure and water use structure are analyzed. Results show that: (1) correlation between industrial structure and water use structure in Wanjiang City Belt is all above 0. 5,belonging to medium association; ( 2 ) The coupling degree of industrial structure and water consumption structure shows an obvious phase, which is generally inverted U type and can be divided into three stages according to the numerical changes, which comprise running-in type (2005-2006),antagonistic type (2007-2009), primary coordination type and running-in type (2010-2014); (3) the coupling coordination types of cities in Wanjiang City Belt are different, Hefei and Wuhu are of the primary coordination type; Ma?anshan and Tongling belong to the type of running-in Chuzhou, Xuancheng and Chizhou are the antagonistic type; Anqingand Lu^an belong to the maladjustment type.
