摘要： 本文给出了划分亚热带北界的模糊综合评判模型,应用此模型确定了陕西省境内亚热带北界的最佳位置,解决了亚热带北界过渡带和指标的数值化问题。

Abstract: In this paper, the mathematical model of Fuzzy comprehensive judgement of the division of the north sub-tropical belt is preposed.The division of the north sub-tropical belt in Shaanxi province is carried out with this model, the concrete location is defined, and the quantitative problems of transitional belt and indices are solved.This not only changes the traditional qualitative division of the north sub-tropical belt into quantitative one and promotes its accuracy, but also liberates the division of boundaries from absolute affirmation and negation, and thus various transitional states appear.
