| Abstract: | The reasonable forecasting water demand is the key to optimizing the allocation of water resources. For the prediction of industrial water demand in Zhengzhou City in 2025 and 2030, quota method, regression analysis and system dynamics method were used to carry out a deterministic water demand prediction. Based on the results of three methods, random number generation and confidence interval algorithm were adopted to calculate the water demand of 95% confidence interval. The results show that the industrial water demand of Zhengzhou is 7.086×108-7.163×108m3 in 2025 and 8.619×108-8.876×108m3 in 2030. The research results have certain theoretical and practical significance for guiding the sustainable utilization of regional water resources. |
