Abstract:
Beijing Tianjin Hebei region,located in the "capital circle" of China,has an extremely important strategic position.The shortage of water resources has become one of the factors that seriously restrict its economic and social developments.Based on the data of water resources utilization and urban economic development from 2000 to 2016,this study firstly investigated the spatiotemporal variations of quantity,structure and efficiency of water resources in Beijing Tianjin Hebei region with coefficient of variation and the Theil coefficient.Secondly,the grey correlation method was used to explore the correlation degree between the types of water resources utilization and the indicators of urban economic development.Thirdly,the quadratic regression model was adopted to analyze the impacts of industrial structure upon agricultural and industrial water,focusing on the relationship between urban economic development and domestic water consumption.The results showed that:(1)There was a large spatial difference in water use between the BeijingTianjin Hebei region,especially in the spatial imbalance between domestic water consumption and industrial water consumption,due to regional economic and development levels;(2) There was a high correlation between the index of urban economic development and the types of water resources utilization in Beijing Tianjin Hebei region,and the industrial structure had the greatest correlation with water resources utilization.Beijing′s domestic water consumption was significantly affected by urban economic development,while Tianjin′s was by the industrial water consumption,and Hebei was by the industrial and agricultural water consumption;(3) There was a better regression relationship between industrial structure and water consumption in Beijing Tianjin Hebei region (p<0.01),among which Beijing and Tianjin had the fastest growth rate of domestic water consumption,while the increase of water price has not played a role in restraining and reducing domestic water consumption in this region.
