摘要
模糊数学是一门新兴的学科,1965年美国控制论专家L·A·Zaden教授发表了奠基性的论文“Fuzzy sets”,意味着模糊数学的诞生。现在,这门学科发展很快,已在信息处理、自动控制、天气预报、医疗诊断、经济学、管理科学等领域得到广泛应用,并开始渗入土坡地理学领域。本文拟就新疆盐土类型亚类一级的区分进行模糊数值分析,以探讨模糊数学在土壤分类问题上的实用意义。
The author in this thesis collected sixteen samples of the solonchakin Xinjiang, and picked out six variables from each. The fuzzy clusteranalysis was carried out after the original data were standarizedlyprocessed. The calculating result is that the seven types of soil, thediluvion solonchak, the relic solonchak, the model solonchak, the meadowsolonchak, the desert solonchak, the bog solonchak and the mineralsolonchak changed into the eight types of the following…the diluvionsolonchak, the velic solonchak, the meadow solonchak, the sodasolonchak, the model solonchak, the brown desert forest solonchak,the bog solonchak and the mineral solonchak.The results reveals thatunder the data properly measured and the soil samples properlycollected, the fuzzy cluster analysis is an effective way of studying theclassification of Xinjiang fuzzy cluster soil type.
