通过对南极长城站区寒冻风化速率的观测和分析 ,结合气温等因素的变化 ,讨论了该区寒冻风化与影响因素之间的关系 .研究表明 ,该区夏季风化速率为冬季的 3.6～ 7.5倍 ;海拔较高的地方风化速率比海拔低的高 1.2 8～ 3.35倍 ;岩壁朝向东、东南的风化强度比朝向北、北西的大 2 .6～ 16倍 .低温年份的风化速率仅有高温年份的 7.2 %～ 16 .6 % .与世界其它冰缘区的风化速率对比 ,本区寒冻风化速率属中等水平 Through the observation and analysis of the freezing weathering rate of the Great Wall Station in Antarctica and the change of temperature and other factors, the relationship between the weathering and the influencing factors of the freezing weather in this area is discussed. The results show that the summer weathering rate in this area is 3.6 ~ 7.5 times higher than that in the upper reaches, and the weathering rates at higher altitudes were 1.2 8-3.35 times higher than those at the lower elevations. The weathered intensity of the rock wall facing the east and southeast was 2.6-6 times larger than those toward the north and the northwest. 7.2% ~ 16.6% of the year with high temperature.Comparing with the weathering rates of other ice-edge areas in the world, the rates of freezing and weathering in this area are moderate
