摘要：

传统的物元模型用于水安全评价,当指标数较多时需要设计很多关联函数,设计和计算工作量皆很大,实际使用不便。为减少关联函数的设计并使之规范化,本研究提出了基于指标规范值的区域水安全评价的物元模型,即在对水安全23项常用指标适当设计参照值和对指标值进行规范变换的基础上,按各子系统将指标归为5类,同类指标设计为相同的关联函数,从而使设计和计算工作量大为简化。以山东省水安全评价为例验证了指标规范值的物元模型在水安全评价中的实用性,并与属性识别理论的评价结果进行了比较。结果表明:该评价模型简单实用,结果与实际符合较好,可为水安全评价提供一种新的参考方法。

Abstract:

As the traditional matter-element method has many indexes for water safety assessment, many correlation functions are necessary for design, which will lead to great inconvenience. In order to reduce the number of the designed correlation function and to normalize the correlation function, the matter-element assessment model of water safety was studied based on normalized indexes values. On the basis of setting index reference values of 23 common indexes and normalizing transformation for indexes, the 23 common indexes were classified into 5 categories according to the subsystems, and similar indexes were designed for the same correlation function, which could greatly reduce the work of design and calculation. Taking Shandong Province as an example, the application of the matter-element model was proposed based on normalized index values to assess the water safety in details. Furthermore, the results were compared with that of the attribute recognition theory. The comparison results showed that the matter-element model based on normalized index values was an effective assessment and analysis method with simplicity, practicability and reliability.
