摘要
本文建立了划分自然带界线的模糊聚类数学模型,并以中国亚热带西段北界为例,确定了其具体位置。它解决了指标数值化和自然带界线具有模糊性的问题,削弱了人为因素的影响,提高了精度。该模型还具有广泛的适应性。
In this paper, the mathematical model of Fuzzy cluster judgement of the division of the natural belts is proposed. The division of the north subtropical bell of the west sector of China is carried out with this model; the concrete location is defined, and the fuzzy characteristic of transitional belt is reflect-ed. This not only changes the traditional qualitative division of the natural belts into quantitative one and promotes its accuracy, but also liberates the division of boundaries from absolute affirmation and negation.
