摘要

为研究山东所在块体及周边地块间的地壳相对运动状态,利用2001年以来中国地壳运动观测网络以及2007年以来山东GPS观测网的观测结果,使用K-L最佳直线拟合和滑动傅里叶法得到基线变化年周期,以此对处于不同地块的GPS基准站间基线变化趋势进行分析,得出近期山东内部及周边地块间的地壳运动特征。并利用GPS资料分析了2011年3月11日日本9.0级强震对山东地区的影响。
In order to study the present movement state of Shandong and surrounding blocks,GPS data from the Crustal Movement Observation Network of China(CMONOC) and the Continuous Observation GPS Network of Shandong Province was used and thus analyzed the baselines between GPS stations on different blocks.Using the K-L best straight line fitting and Slide Fourier method,we got the baselines changes by year cycle,and analyzed the trend of baselines crossing different blocks.In addition,we obtain the present crustal movement characteristics of Shandong and surrounding blocks,and analyzed the influence of Japanese earthquake of 9.0 on Shandong area.
