Based on the one-dimensional water quality modelling theory, this paper discusses the impact of different calculation methods on water environment capacity in different water functional areas. Through a case study of the Yinma River in Jilin province, in the same condition, the influence of four calculation methods (1. section-beginning control and no pollution sources generalization; 2. section-beginning control and uniform pollution sources generalization; 3. section-end control and no pollution sources generalization; 4. section-end control and uniform pollution sources generalization) on the calculated results of water environment capacity were analysed. The calculation results of four calculation methods from big to small are: 4,3,2,1. In the case of considering only one of the model parameters, control section or pollution source generalization, the percentage improvements of water environment capacity are the same.

Based on the one-dimensional water quality modelling theory, this paper discusses the impact of different calculation methods on water environment capacity in different water functional areas. Through a case study of the Yinma River in Jilin province, in the same condition, the influence of four calculation methods (1. section-beginning control and no pollution sources generalization; 2. section-beginning control and uniform pollution sources generalization; 3. section-end control and no pollution sources generalization; 4. section-end control and uniform pollution sources generalization) on the calculated results of water environment capacity were analysed. The calculation results of four calculation methods from big to small are: 4,3,2,1. In the case of considering only one of the model parameters, control section or pollution source generalization, the percentage improvements of water environment capacity are the same.
