AB - The water carrying capacity and the water carrying state are two similar  concepts, and there are no clear boundaries between them, so there exists  confusion during the evaluation process. Additionally, current evaluation  methods cannot meet the dynamic change requirements under different control  measures. This study emphasizes the difference between the two concepts and  points out that the core of the water carrying capacity is the determination  of thresholds. In contrast, that of the water carrying state is a state  evaluation. A coupled iterative model is proposed based on the extended  Fourier amplitude sensitivity test algorithm and a modified state-space  method. In order to evaluate and regulate the water carrying state  dynamically, the iterative calculation is introduced into the evaluation of  the water carrying state. During the iterative process, the water resources  in the non-overloaded area are allocated to the surrounding adjacent  overloaded areas until the water resource carrying state of the original  over-loaded area reaches an acceptable level, and the total amount of water  resources allocation during multiple iterations is given. In this study, we  take Jilin Province as the research object. We hope that the iterative  coupling model of the water carrying state proposed in this paper can be  widely applied in the future.
