摘要
根据地质构造特征,我们对青藏东北缘地区进行了活动块体的划分,运用GPS观察和检测资料,用刚体旋转加线性应变模型与刚体旋转加均匀应变模型来调研该地区地壳形变场,并对这两种模型在该区形变场分析中的应用情况进行了比较,得出的就是刚体旋转加均匀应变模型比刚体旋转加线性能更好地描述这个区域的形变场。
Active block demarcation is done on the basis of geologic tectonic characteristic in northeast margin of Qinghai-Tibet. This paper makes research on crustal deformation field with REHSM and RELSM singly with data observed by GPS, compares the models, and reveals that REHSM is better than RELSM in northeast margin of Qinghai-Tibet deformation field analysis.
