Abstract
Based on the perspective of human-water relations coordination, the TOPSIS model, coupled with the coordinated development model quantitatively analyses the water resources carrying capacity and spatial-temporal evolution of the four provinces and regions of the Liaohe River Basin and the degree of the subsystems' carrying capacity and coordinated development from 2005 to 2020. The results show that: a. The fluctuation trend of the region as a whole from 2005 to 2020 indicates that the state of water resources carrying capacity is unstable. b. The fluctuation range of the carrying capacity of the four subsystems is large, and the fluctuation of the water resources and water ecology subsystems is more significant, and the carrying capacity of the water resources and water ecology subsystems is lower than that of the water society and water economy subsystems, and the amount of water resources development and utilisation has exceeded the water resources subsystems' carrying capacity Water resources development and utilisation has exceeded the carrying capacity of the water resources subsystem.
