Multi-Dimensional Factor Analysis for Assessing Region Water Resources Carrying Capacity

Abstract

Scientific water resource carrying capacity (WRCC) evaluations are necessary for providing guidance for the sustainable utilization of water resources. Under the background of increasing global water resources crisis, this paper takes Shandong Province of China as the research area, establishes a multi-dimensional intergration index of WRCC, and uses factor analysis to measure the WRCC from 2010 to 2019. The analysis results show that the index system of WRCC constructed by using four dimensions and 20 indicators is scientific and practical to a certain extent. Factor analysis is used to reduce the dimension of 20 indicators to 4 factors, and finally calculate the factor scores, so as to measure and rank the WRCC from 2010 to 2019.
