| Abstract: | In this paper, various dominating factors affecting crustal movement of the coastal zone in eastern China are analyzed, and major characteristics of crustal movement are summarized. Subduction of the pacific plate and Philippine plate and southeastward "escape" of Qinghai-Tibet plateau are believed to be dominating factors affecting crustal movement of that zone. Undoubtedly, it is a best way to monitor this kind of large-scale crustal movement with GPS technique. The feasibility of monitoring crustal movement based on GPS technique is discussed, and a preliminary experiment was carried out to test the scheme in 1998. In this scheme, a monitoring network for crustal movement with GPS technique was established on the basis of five GPS stations distributing well-proportioned along the coastal zone in eastern China. The experimental results indicate that precision of station coordinates based on GPS technique has reached millimeter level, and baseline relative precision has reached 10~(-9), which satisfies the precision requirement of monitoring crustal movement on the whole. |
