摘要
物元可拓方法是从定性和定量两个角度去处理现实世界中矛盾问题的一种新方法。文章在基于可拓工程方法的基础上,利用物元模型理论,建立了地下水质量评价模型,通过计算综合关联度确定地下水质量等级。由于物元分析中的关联度引入了负数,保证了信息的完整性,能较完整地反映事物的综合质量水平,因此,评价结果更为客观、准确。应用结果表明该方法是合理可行的。
Extension method is a new method to solve the realistic contradiction qualitatively and quantificationally. Based on the method of extension, the model for the groundwater quality assessment is established by means of theory of matter - element model ,and then the grade of groundwater quality is obtained by calculating the comprehensive correlated degree. Being introduced negative in the connection degree in matter element analysis, the use of the method guarantees the information integrity and reflects the integrated quality level of a matter perfectly and the assessment result is made more objective and accurate. The application results show that the method is reliable and feasible.
