| Abstract: |
| Considering the water resources condition in the catchments of the Shiyang River located in Wuwei, we generalized the system of water resources there, and established a network simulation model for rational allocation of water resources in the catchments, which combined water requirements for ecological environment and normal water consump-tion. Meanwhile, this model proposed, based on the goal, the constraints and boundary function, a network simulation computation flow. According to the methods of the typical years, the allocation of water resources is simulated in different guaranteed efficiency and different horizontal years, and the scheme is put forward for the mean and different horizontal years, so as to make a foundation for alleviating the contradiction among supply and demand of water in the catchments, developing local economy and planning the environmental protection. |
