Hu, Y.; Yao, L., and Hu, Q., 2020. Evaluation of water resources carrying capacity in Jiangxi province based on principal component analysis. In: Hu, C. and Cai, M.

Water is the source of life as well as an essential factor for social and economic development. By analyzing water resources carrying capacity (WRCC), it can be determined whether the water resources in a region match its socioeconomic development. Based on related data from 2013 to 2018, the development trends of the WRCC of Jiangxi Province and its 11 cities were analyzed via principal component analysis. The results showed that the WRCC of Jiangxi Province had continuously improved, rising rapidly from 2013 to 2016 and slowing down from 2016 to 2018. Among the 11 cities, five had improvements in WRCC on the whole, and six cities showed an increasing trend followed by a decreasing trend. According to the specific situations of Jiangxi Province and its 11 cities, the causes for the changes in WRCC were analyzed. Based on this, relevant suggestions were put forward to provide guidelines for the reasonable development and protection of water resources in Jiangxi Province.
