| 摘 要： | 公路自然区划具有很强的模糊性,为了在区划工作中减少人为主观因素的影响,使所作的公路自然区划更具科学性,本文以模糊数学理论为基础,提出了以模糊聚类分区方法进行东部温润季冻区三级自然区划的分区思想.以鲁豫轻冻区(Ⅱ5)三级自然区划为例,提炼分区指标,建立指标权重向量,构建模糊相似矩阵,依据自然因素对公路工程综合影响的相近程度,采用直接聚类法进行聚类分区,并结合地理相关性分析法对模型分区结果进行适当调整,最终确定了鲁豫轻冻区(Ⅱ5)的三级自然区划方案.

| Abstract: | Based on the fuzzy mathematics theory,the zoning idea that the third rank natural division should be made in east seasonal frost region with fuzzy clustering method was put forward.Taking Luyu light frost region(Ⅱ5) as example,the target of zoning was abstracted,a proportion vector of the target was made,and a fuzzy similarity matrix was formed.Base on the similarity extent of the general impact of natural factors on the highway engineering,the clustering zoning was made by direct clustering method.Combing the relative analysis of geography,the results of the model zoning were adjusted.Thus the third rank natural division was obtained in Luyu light frost region(Ⅱ5). |
