中文摘要：

干旱区城镇化的发展与水资源密切相关,实现两者的协调对区域可持续发展至关重要。以河西走廊20个县（区）为研究单元,构建城镇化与水资源效益的综合评价指标体系,使用熵值法赋权计算河西走廊2000、2005、2010、2013年的城镇化水平和水资源效益,运用探索性空间数据分析（ESDA）和协调发展模型,分析4个时间节点城镇化水平与水资源效益的集聚扩散状态及其时空格局和两者的协调性。结果表明：河西走廊城镇化水平的空间分布状态不稳定,变化显著;水资源效益呈现出分散的时空格局并保持相对稳定,且河西走廊及其3个内陆河流域的城镇化水平与水资源效益差异明显。同时,城镇化水平与水资源效益的协调发展水平逐步提高,协调发展类型主要为低和较低,且3大内陆河流域之间存在差异。

英文摘要：

The development of urbanization is closely related to water resources in arid area. It is of extreme importance to realize the urban sustainable development and coordinate the relationship between urbanization and water resources benefits. In this study,twenty counties（ districts） in the Hexi Corridor were taken as the research areas,the comprehensive evaluation index systems of urbanization and water resources benefits were developed,and the urbanization level and water resources benefits in the study area in the years of 2000,2005,2010 and 2013 were estimated with the entropy method. The exploratory spatial data analysis and the coordinated development model were used to analyze the agglomeration or diffusion status,spatiotemporal pattern and coordination degree between urbanization and water resources benefits. The results showed that the spatial distribution of urbanization level in the Hexi Corridor was not stable and changed significantly in the study years; the spatiotemporal pattern of water resources benefits in different years was in a dispersed pattern and kept stable relatively. Difference of urbanization level and water resources benefits was obvious in the Hexi Corridor and its three main inland river basins. Moreover,the coordinated development of urbanization level and water resources benefits was generally low but was gradually improved,and its difference among the three main inland river basins in the corridor was obvious.
