- 摘要:
- 为揭示城市化与水资源系统耦合协调的内在规律,以云南省为研究区域,运用指标体系构建、纵横向拉开档次法和耦合协调模型等方法探究了城市化与水资源系统耦合协调的时空格局及形成机理。结果表明:(1)2010—2017年,云南省城市化与水资源系统处于初级耦合协调状态。(2)2010年,唯一的基本协调类型分布在滇中地区的昆明市; 中度协调类型零星分布; 轻度失调类型独占滇西北地区的迪庆州; 初级协调类型主要分布在滇西、滇西南和滇东南地区。(3)2015年较2010年发生了显著的变化。滇西北地区成对出现轻度失调类型; 滇中和滇南地区集中分布中度协调类型。(4)2017年较2015年有了新的变化。滇西地区的临沧市首次出现中度协调类型; 滇东地区不再有中度协调类型的分布; 滇东、滇西和滇西南地区集中分布着初级协调类型。其形成机理为:(1)GDP影响着城市化水平。(2)城市化水平和水资源系统共同决定着云南省耦合协调度的时空演变。(3)GDP和水资源系统指数的区域差异导致了耦合协调度的区域差异。综上,云南省城市化与水资源系统耦合协调的空间格局发生了演变,存在着3个方面的演变机制。
- Abstract:
- In order to reveal the inherent laws of the coupling coordination state between urbanisation and water resources system, Yunnan Province was taken as an object of study. The temporal and spatial pattern and its formation mechanisms in relation to the coupling coordination between urbanisation and water resources system were explored by using methods of: the construction of indicator system, vertical-and-horizontal scatter-degree and the coupled coordination model. The results show that:(1)The urbanisation and water resources system in Yunnan Province from 2010 to 2017 is in a primary coupled coordination state.(2)In 2010, the sole type of basic coordination layed in Kunming City in Central Yunnan Province; the moderate coordination type scattered in different regions; the slightly imbalanced coordination type dominates Diqing Tibetan Autonomous Prefecture of the northwest of Yunnan Province; the primary coordination type was distributed among the regions of the west, southwest and southeast of Yunnan Province.(3)Compared with 2010, there is an obvious change in the distribution of the spatial coupling coordination in 2015. The northwest of Yunnan Province witnessed a slightly imbalanced coordination type, and the moderate coordination type gathered in the central and south of Yunnan Province.(4)Compared with 2015, the spatial pattern of coupling coordination took on new changes in 2017. The moderate coordination type first appeared in Lincang City in the west of Yunnan Province. There was no moderate coordination type in the east of Yunnan Province. The primary coupled coordination type was distributed among the regions of the east, west and southwest of Yunnan Province. Their formation mechanisms included three aspects. First, the GDP affected the level of urbanisation. Second, the GDP and urbanisation jointly determined the temporal and spatial evolution of the coupling coordination in Yunnan Province. And third, the regional differences of GDP and water resources system index lead to the regional difference of coupling coordination. To sum up, the spatial pattern of the coupling coordination between urbanisation and water resources system in Yunnan Province has evolved with three evolutionary mechanisms.
