选择Global Morans I和Getis-Ord Gi*两个空间关联指数和协调发展度函数探讨新疆1990、1995、2000年和2005年水资源效益的空间格局和冷热点区域演化,在此基础上对水资源效益和城镇化的协调性进行分析。结果显示:①新疆各县市水资源效益在空间上明显呈以天山北坡为核心的集聚分布状态。②新疆水资源效益冷热点区域的演化呈现出不同的演变轨迹。③新疆水资源效益与城镇化协调发展程度的空间格局演变相对稳定,协调发展程度高的区域呈现扩张趋势,协调发展程度低的区域数量收敛态势明显。二者的协调类型可分为同步协调型、水资源效益滞后型、城镇化滞后型、逐步磨合型和低级协调型5种。
In this paper, two spatial correlation indices, such as Global Moran’s I and Getis-Ord Gi *, are used to explore the spatial distribution of water resources benefits and the regional evolution of hot and cold water points in 1990, 1995, 2000 and 2005 in Xinjiang Water efficiency and urbanization coordination analysis. The results show that: ① The water resources benefits of counties and cities in Xinjiang are obviously distributed in the space with the northern slope of Tianshan as the core. ② The evolution of hot and cold water areas in Xinjiang shows a different evolution trajectory. ③ The spatial pattern of the coordinated development of water resources benefits and urbanization in Xinjiang shows a relatively stable evolution of spatial pattern. Areas with high levels of coordinated development show an expanding trend, while areas with low levels of coordinated development have a clear convergence trend. The two types of coordination can be divided into synchronous coordination type, water resource efficiency lag type, urbanization lag type, gradually grinding type and low-level coordination type 5.
