| Abstract: |
| 【Objective】This study described the complex relationship of water resources system and solve the difficult allocation problem using simulation method to provide basis for reasonable development and utilization of regional water resources.【Method】The optimal allocation model for water resources was established with the consideration of economic,social,ecological and environmental benefits and it was solved by adopting the simulated annealing genetic algorithm.Then,the model was used to obtain the optimal configuration of water resources in Xianyang.【Result】Based on the established model and under the condition of 50% guaranteed rate,the estimated surface water,ground water,water transfer and wastewater reuse in 2020 for Xianyang were 69 020×104 m3,53 433×104 m3,23 435×104 m3,and 7 900×104 m3 and 88 825×104 m3,46 533×104 m3,46 310×104 m3,and 12 100×104 m3 in 2030,respectively.Compared with the original water supply,the total water supply was reduced by 322.09×104 m3 and 432.46×104 m3 in 2020 and 2030.Except for agricultural water,requirements of other water users could be met.【Conclusion】The optimal allocation results of water resources by established model using simulated annealing-genetic algorithm were reasonable and feasible,and they can be regarded as decision making basis.The simulated annealing-genetic algorithm has the advantage of fast convergence and optimization,and can be used in water resources allocation. |
