Assessment of Water Security and Identification of Driving Factors for Shaanxi Urban Agglomeration in the Northern Foothills of Qinling Mountains,China Based on DPSIR Model
Water security assessment is essential for water resources development and utilization and regional development.To strengthen the sustainable construction of Shaanxi urban agglomeration in the northern foothills of Qinling Mountains and support the green development of the"Central Water Tower",the water security assessment system for Shaanxi urban agglomeration in the northern foothills of Qinling Mountains was constructed based on DPSIR model.The regional water security from 2011 to 2021 was assessed and graded by combining the subjective-objective weighting method and the fuzzy comprehensive assessment method,and its driving factors were analyzed by the gray correlation method.The results show that the changes of water security status in Shaanxi urban agglomeration at the northern foothills of Qinling Mountains from 2011 to 2021 are consistent,and the fluctuation is steadily increasing.The water security level in Xi'an has shown a significant upward trend compared to that in Baoji and Weinan,and it has been in a state of no-alert since 2021.Baoji has always maintained a low-alert status,while Weinan has been in a medium-alert status for a long time.These water security status and development trend are closely associated with ten driving factors,including per capita GDP,annual precipitation,and per capita water consumption,etc.Among them,economic factors are the basic guarantee for the consistency of water security level,while social and ecological factors are the main reasons for the differences in water security.
