基于假设检验的刚性板块台站选取及全球板块运动模型的建立

CHOICE OF OBSERVATION STATIONS FOR RIGID PLATE AND ESTABLISHMENT OF GLOBAL PLATE MOTION MODEL BASED ON HYPOTHESIS TESTING

提出采用正态μ假设检验方法,自动探测并剔除板块内异常台站,经统计假设检验和迭代平差,逐步逼近刚性板块稳定台站。运用该方法成功确定了全球九大主要板块稳定台站,建立了高精度ITRF2005VEL全球板块背景场及运动模型。结果表明,所建模型与其他模型相比,整体一致,精度明显提高。

A new method of normal/~ hypothesis testing was proposed, which can detect and remove the abnor- mal stations automatically. Through statistical testing and iterative adjustment, the stable stations for the rigid plate were confirmed. The rigid stations in global 9 plates were qualified successfully using the method and the global plate motion model based on ITRF2005VEL was constructed. The result shows that the construction model agrees well with other models as a whole and the precision is higher.
