基于VSD模型的陕南城市群水资源脆弱性评价及影响因子研究
Water Resource Vulnerability Assessment and Impact Factors of Southern Shaanxi Urban Agglomeration Based on VSD Model
摘要
Abstract
[Objective]The aims of this study are to construct a water resource vulnerability model for the southern Shaanxi urban agglomeration based on the coupling effect of society,economy,and ecology,to clarify the state of water resource vulnerability,to determine the influencing factors,and to contribute to the harmony between human and water in the Qinling region.[Methods]In view of this,the water resource vulnerability of the southern Shaanxi urban agglomeration was evaluated based on the Vulnerability Scoping Diagram(VSD),and further its influencing factors under the coupling of society,economy and ecology were identified by using multivariate statistical methods.[Results]The overall trend of water resource vulnerability in southern Shaanxi was most similar to that in Shangluo City from 2011 to 2020.Except for extreme vulnerability in 2011,it remained basically in a mild fragile state.However,the water resource vulnerability levels in Hanzhong City and Ankang City were relatively high,and the degree of water security guarantee was relatively low.The main control factors for the vulnerability of water resources included ecological environment water consumption,per capita water resources,annual precipitation.Optimizing the allocation of water consumption in the ecological environment,and strengthening the monitoring of annual precipitation and per capita water resources will become the new focus on reducing water resource vulnerability in the southern Shaanxi urban agglomeration.[Conclusion]The improvement of water resource system security in the southern Shaanxi urban agglomeration is related to the local emphasis on water ecological civilization construction and coordinated development with society and economy.In addition,the VSD model constructed in this paper is suitable for evaluating the vulnerability of water resources in the southern Shaanxi urban agglomeration,and can provide theoretical guidance for alleviating the contradiction among people,city,and water.关键词
