Based on the characteristics of arid regions in the central and southern Ningxia，firstly we constructed the theoretical framework about rational allocation of water resources based on ecological priority, which supplemented and improved the theoretical system on rational allocation of water resources for sustainable development. On the basis of theoretical research, depending on its characteristic of water resources：pumping water from Yellow River in the north, piloting water from Jing River in the south and regional water resources, which formed a mixing water supply pattern of "pumping, piloting, storage". The theory of water resource allocation system was perfected. Then the mathematical model for the rational allocation of water resources was established on the basis of biggest benefit combined with economy, society and ecology. The model coincided the ecological water and domestic water benefit into the overall benefits, and provides them larger benefit coefficient and the priority order coefficient to realize the reasonable allocation of water resources on ecological priority mode. Finally, the results of allocation are analysed in detail, which provides constructive suggestions and guiding direction for the study of the rational allocation of regional water resources.
基于宁夏中部和南部干旱地区的特点，首先构建了基于生态优先的水资源合理配置理论框架，补充和完善了可持续发展的水资源合理配置理论体系。在理论研究的基础上，依托北部引黄、南部泾河调水和区域水资源的特点，形成了“引、调、蓄”相结合的混合供水格局，完善了水资源配置制度理论。然后，在最大效益与经济、社会和生态相结合的基础上，建立了水资源合理配置的数学模型。该模型将生态用水和生活用水效益纳入整体效益，赋予其更大的效益系数和优先顺序系数，以实现生态优先模式下的水资源合理配置。最后，详细分析了配置结果，为区域水资源合理配置研究提供了建设性的建议和指导方向。
