河西走廊城镇化与水资源效益的时空格局演变
Spatiotemporal Pattern Evolution of Urbanization and Water Resources Benefits in the Hexi Corridor
摘要
Abstract
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.关键词
