Assessment of Water Resources Carrying Capacity and Temporal-spatial Variation Characteristics of Nine Provinces Along the Yellow River,China
Evaluating the coordination among water resources,social economy,and ecological environment could offer guidance for the utilization and management of water resources in the Yellow River.An evaluation index system for water resources carrying capacity was constructed based on the subsystems of water resources,social economy,and ecological environment.The VIKOR method was utilized to assess the water resources carrying capacity of nine provinces along the Yellow River from 2008 to 2021.Additionally,the Mantel test method was introduced to analyze the categories of water resources carrying capacity and their influencing factors.The results show that the water resources carrying capacity of nine provinces along the Yellow River have exhibited a continuous upward trend from 2008 to 2021.With the enhancement of social and economic development and ecological environment protection,the level of water resources carrying capacity has notably increased after 2015.Spatially,there is a pattern of strong capacity in the west,followed by the east,and weaker capacity in the middle.Among them,Qinghai is the strongest,and Ningxia is the weakest.The types of water resources carrying capacity vary in each province.Qinghai,Gansu and Shaanxi fall under the category of water resources endowment type,while Ningxia and Inner Mongolia are classified as water resources-social economy type.Sichuan,Shanxi,Henan,and Shandong are categorized as comprehensive type.Water resources endowment forms the basis of water resources carrying capacity in nine provinces along the Yellow River.Factors such as water production modulus,per capita water resources,and precipitation depth are key determinants of the water resources subsystem.Moreover,there is a high reliance on the social economy and ecological environment subsystem,which necessitate enhancement through industrial upgrading,improving water use efficiency,and ecological environment protection.
