洪水分类是提高洪水预测精度的一个有效途径.根据可变集的对立统一数学定理,提出洪水分类可变集原理与方法,将辩证法基本规律的数学定理应用于洪水分类.对在工程技术领域中运用辩证思维分析问题、研究问题具有启迪意义.结合黄河支流秃尾河流域15场洪水分类实例,通过对分类结果的比较与分析,指出集对分析分类法存在的错误,而可变集方法理论严谨,计算简便,且其分类结果客观、精确,符合实际情况.研究表明在解决分类问题中,不但要求成果的合理性,而且要求方法的科学性.
Flood classification is an effective way to improve the accuracy of flood forecasting.According to the uniform set of opposites mathematical theorem, a variable set principle and method of flood classification is proposed, and the mathematical theorem of dialectical basic law is applied to flood classification.In the field of engineering technology Using dialectical thinking to analyze the problems, the study has enlightening significance.Combining with the example of 15 floods in the Tuwei river basin, which is a tributary of the Yellow River, by comparing and analyzing the classification results, it points out the errors in the set-pair analysis and taxonomy, while the theory of the variable set method is rigorous , The calculation is simple, and the classification result is objective, accurate and in line with the actual situation.Research shows that in solving the classification problem, not only the rationality of the result but also the scientificity of the method are required.
