摘要

Abstract

Based on the Maximum Frozen Soil Depth and annual mean temperature and Extreme low temperature across seven meteorological stations in Altay region from 1963-2012,using linear regression,Mann-Kendall mutation detection,Hurst R/S analysis method,the temporal evolution and spatial distribution of maximum depth and tempera-tures of frozen soil were analyzed .The results show:the mean-square deviation and coefficient of variation of maximum appears in Jimunai;the maximum depth have declined by 0 .574 cm·a-1;The annual maximum frozen depth almost al-ways occurs in February and March;Maximum Frozen Soil Depth appear an abrupt decrease in 1986-1987s in Altay re-gion;the deepest of annual Extreme and maximum of average and average of maximum depth appears in Qinghe;The Maximum Frozen Soil Depth and are negatively correlated with annual mean temperature and Extreme low temperature and the correlation coefficients are -0 .508 and -0 .293 .
