判别水资源开发利用方案是否符合可持续性要求是当今水资源评价的关键环节.将水资源开发利用看成是一个涉及经济、环境、社会效益等多个目标的连续过程,在探讨多目标决策的非劣权衡率和无差权衡率及其相互关系的基础上,根据水资源开发利用历程中决策者偏好结构的不同,将多目标决策权衡率的涵义扩展到与时间相关,揭示了不同水资源利用模式下经济效益目标和环境效益目标之间的权衡率随时间变化的动态演变特性,为水资源可持续利用方案的识别和评价提供了相应依据.实例分析验证了理论的有效性,可供决策层参考.
Judging whether the water resources development and utilization program meets the requirements of sustainability is a key link in water resources assessment today.Water resources development and utilization is regarded as a continuous process involving multiple objectives such as economy, environment and social benefits, Based on the different preference structure of decision makers in the process of development and utilization of water resources, the implication of the multi-objective decision-making rate is extended to relate with time, which reveals that different water The dynamic evolution of the trade-off ratio between economic benefits and environmental benefits under the resource utilization model over time shows the corresponding evidences for the identification and evaluation of the sustainable utilization of water resources.An example analysis validates the validity of the theory, For decision-making reference.
