一、引言 1965年美国控制学专家I、A、Zdaeh提出了模糊集的概念,应用模糊数学处理模糊数学问题,十几年来随着模糊数学的发展,很好地解决了电子计算技术、自动控制、图象识别和社会科学等许多学科中的判别分类,推动着科学技术的发展。生物学分类需要描述的物种数以万计,而且许多特征由于生态环境的变化及技术措施的制约,引起偶然变异,产生许多不肯定性问题。这些问题已开始采用模糊数学予于解决。如依据花、果、叶等特征进行植物物种的鉴定,依据气象因子区划植物引种区等等。
I. INTRODUCTION In 1965, American control experts I, A and Zdaeh proposed the concept of fuzzy sets and applied fuzzy mathematics to deal with the problem of fuzzy mathematics. With the development of fuzzy mathematics over the past decade, they have solved the problems of electronic computing technology, automatic control , Image recognition and social sciences and many other disciplines in the classification to promote the development of science and technology. There are tens of thousands of species to be described in the taxonomy of biology, and many of the traits cause accidental variation due to changes in the ecological environment and constraints of technical measures, resulting in many uncertainties. These problems have begun to be solved by fuzzy mathematics. Such as flowers, fruits, leaves and other characteristics of the identification of plant species, according to meteorological factors zoning plant introduction and so on.
