Abstract:

n this paper we choose five glaciers as studying target, each target has three elements of Na++K+, Ca2+ and Mg2+, using fuzzy cluster analysis we can study them.The results indicate that the relation among the glaciers change with the level λ. As the λ is high, each glacier has its character and no relation with others. With the decreasing of λ, The common character between the Guliya glacier and Tuomufeng glacier appears. With the further decreasing of λ, the common character between the Hailuogou glacier and the Dasuopu glacier appears. Decreasing λ more, the glaciers can be divided into two parts: the Antarctic Nelson station and the Qingzang Plateau glaciers. This indicates that the environment and climate in the Antarctic Nelson station is different from that in the Qingzang Plateau. As λ decreasing more, the boundaries among the glaciers become indistinct. They can be put in one group.
