Evaluation of Water Resources Carrying Capacity Using Principal Component Analysis: An Empirical Study in Huai’an, Jiangsu, China

Abstract

With the rapid development of urbanization, problems such as the tight supply and demand of water resources and the pollution of the water environment have become increasingly prominent, and the pressure on the carrying capacity of water resources has gradually increased. In order to better promote the sustainable development of cities, it is extremely important to coordinate the relationship between water resources and economic society. This study analyzed the current research status of water resources carrying capacity from two aspects, i.e., research perspective and research methodology, established an innovative evaluation system, and used the principal component analysis to analyze the water resources carrying capacity in Huai’an City, an important city in China’s Huaihe River Ecological Economic Zone. Based on the results, it is found that the water resources carrying capacity of Huai’an City has been declining year by year from 2013 to 2019. Based on the evaluation results, suggestions and measures to improve the water resources carrying capacity of the empirical city are proposed to provide an important decision basis for the coordinated development of urban economy, society, and water resources.

Evaluation of Urban Resource Environmental Carrying Capacity and Land Spatial Development Suitability in a Semiarid Area of the Yellow River Basin

“…In 2010, Wu Bin used the principal component analysis method to comprehensively evaluate the resource and environmental carrying capacity of Shenzhen, and Bin found that the resource and environmental carrying capacity of Shenzhen showed a downward trend, in general, from 2000 to 2007. Especially after 2003, the situation was more severe due to the influence of resource development and utilization efficiency, ecological environment quality, and economic development level [9]. In 2011, Gao et al used the similarity evaluation model to comprehensively evaluate and analyze the water resource carrying capacity of Ordos City, and they found that the development and utilization of water resources in Ordos City had a considerable scale, and regional water transfer projects could be implemented to solve the problem of water [10].…”

Application of Analytic Hierarchy Process in Comprehensive Evaluation Index of Urban Amenity

“…The determination of weights is a key part of the overall multi-index evaluation method. At present, the most commonly used methods for determining indicator weights are AHP [10,11], entropy method [12], principal component analysis [13], and mean square error decision method. These methods have their advantages in the comprehensive evaluation.…”

Multi-Level Fuzzy Comprehensive Evaluation for Water Resources Carrying Capacity in Xuzhou City, China

“…The increasing water crisis, such as water shortages, water environment pollution, and low water resource utilization, has become a major bottleneck for the regional economy and society's sustainable development. Therefore, it is imperative to rationally allocate the regional water resources in Xuzhou by coordinating the urban water use in all sectors comprehensively [13].…”
