| 摘 要： | 在对新疆北部地区地质构造、构造运动强度、历史强地震活动特征、地壳缩短速率以及局部应力场特征综合研究的基础上,将新疆北部地区划分为阿尔泰地震带、乌鲁木齐、北天山西段、中天山和东天山5个地震构造区带.通过计算上述各构造区带年应变能释放均值、折合震级、不同震级下限的地震年发生率、b值和应变加速释放模型参数m值等参数,对各构造区带中地震活动状态进行了定量分析,进而提取了各构造区带地震活动状态的特征指标,为地震趋势分析和判定提供了定量的依据.

| Abstract: | Based on the comprehensive research on geological structure,tectonic motion strength,history strong earthquake activity,crustal shorten velocity and local stress field characters,the northern Xinijang region is divided into five tectonic regions,they are Altai seismic belt,Urumqi tectonic region,western segment of northern Tianshan mountain,central part of Tianshan mountain and eastern segment of Tianshan mountain.By calculating the mean value of strain energy release,converting magnitude,annual occurrence ... |
