In order to optimize the allocation of water resources and improve the quality of water resources,it is necessary to study the coupling model design method of water quantity and quality protection.The water supply,water demand,comprehensive evaluation index of water environment,total water quality and water balance are taken as constraints,and the ecological environment benefit,economic benefit and social benefit are taken as optimization objectives.The multi-objective coupling model design method of water resource quantity and quality protection is proposed,and the model is solved by particle swarm optimization algorithm.The experimental results show that the quality of water resources is improved and the demand of water resources is reduced by the proposed model,which verifies the effectiveness of the proposed method.
