Evaluation and early warning of water environment carrying capacity in Liaoning province based on control unit: A case study in Zhaosutai river Tieling city control unit

Water environment carrying capacity (WECC) is an important index to investigate the carrying capacity of water environment to human life and production. In this study, the index system method and system dynamics method were combined to calculate the water environment carrying capacity. Zhaosutai riv...
