Index system and fuzzy sets theory for comprehensive evaluation on regulation and storage capacity of underground reservoir
-
摘要: 从维护生态平衡与水资源可持续开发利用的角度定义了地下水库的调蓄能力,提出地下水库调蓄能力综合评价的指标体系。并在模糊模式识别理论与模型的基础上,去除指标间的相关性,建立一种适合于对多指标体系的地下水库调蓄能力进行综合评价的多层模糊模式识别交叉迭代模型。实例应用表明,该模型具有能同时考虑定性与定量指标,又能将迭代结果与决策者经验知识相结合来确定多指标权重的优点,便于推广应用。Abstract: The regulation and storage capacity of an underground reservoir is defined with the viewpoint of keeping ecological balance,the sustainable development and utilization of water resources of a watershed. Then the index system of the compre-hensive evaluation on regulation and storage capacity is established. Furthermore,this paper presents a recognition model of fuzzy pattern with cross iteration for multi-objective and multi-layer system to assess the regulation and the storage capacity of an underground reservoir on condition that the index correlation is eliminated. The model can consider qualitative and quantitative indexes and determine the index weights in multi-objective system through combining cross iteration results with the experience and preference of the decision makers. Finally,the model is applied to evaluate and optimize the regulation and storage capacity of the underground reservoirs in the lower watershed of Liaohe river. The case study shows that the new framework and methodology are scientific,reasonable and easy to use in practice.
