Field observing sites were set to measure frost weathering of bedrock in the Great Wall Station Area of Antarctica from 1988 to 1990. The result show that: (1), the weathering rate is higher in summer that in winter; (2), the weathering rate is greater at higher place that at lower place; (3), the weathering rate is higher in east and southeast slopes than in other slopes; (4), the weathering rate is greater in higher mean annual air temperature year than in lower year
