| 摘 要： | 探讨利用边长变化方法解算区域应变场,并用该方法对1999-2001年中国大陆及周边区域网GPS测站边长变化量进行分析,给出了该期间的中国大陆应变率场变化.分析结果表明:对大范围、密集的GPS测站的边长变化量进行连续变形分析,既能揭示中国大陆地壳应变的总体分布,又能显示局部地区的构造获得.总体上,中国大陆构造的水平变形强...

| Abstract: | A new method for calculating strains based on side length changes is proposed.By use of this method the strains distribution of Chinese mainland in the period of 1999 to 2001 are calculated.The results show that the analysis of the continuous deformation in the large-scale and dense GPS velocity field can reveal not only the integral tectonic characters of Chinese mainland but also the tectonic deformation which have a mutation in the South-North Seismic Belt and is stronger in the west than in the east and... |
