Abstract:This paper calculated the tectonic deformation characteristics of mainland China and the characteristics of the strain field in the plate space distribution, using more than 260 continuous CMONOC sites and more than 2,000 area stations, that are the latest observation data. According to the intensive, wide range of GPS velocity field shows strong east and west weak trends from the entire velocity field in mainland China. The maximum velocity appeared in the Himalayan region, with a general rate between 35 and 42 mm/a. The Sichuan-Yunnan region dextral shear zone formed by the deformation characteristics of the most striking that the southwest of the minimum rate is between 3 to 9 mm/a, north of maximum rate in 17~23 mm/a. It can be seen from the spatial distribution that the largest strain-stress are mainly from the following regions: Himalayan, Kunlun Mountains, Sichuan and the Yunnan areas of fresh water river fault zone, Tianshan region, and Beijing-Tianjin area. The strain rate of the east coast shows tension that is mainly due to the earthquake in Japan in 2011, although the influence of the region has not completely subsided.
