Integrated assessment of water scarcity for Luoyang City, China

With China's rapid population increase and economic growth, more and more large cities in China are facing aggravated water scarcity. Therefore, there is an urgent need to assess water scarcity in large cities. This paper selected Luoyang City, China, as a case study site and proposed six types of assessment indicators for assessing Luoyang's water scarcity. By means of a two-order fuzzy comprehensive judgment method, Luoyang's water scarcity was graded and the impact of each type of assessment indicator was rated on water scarcity. The results provide a scientific basis for the sustainable exploitation, utilization and management of water resources.
