通过研究南北地震带及青藏块体东部地区２０多年来大地形变场演化特征及其与地震活动的呼应关系，发现大地形变既具有时空分布的不均匀性，各分区形变场又具有同时段的宏观相似性；继承性运动是现代地壳运动的总趋势，而运动方式为波浪式、涌动式推进。地壳运动过程中存在着区域应变能积累阶段和释放调整阶段，这可能是地震活动的相对平静与活跃的动力机制。１９９１年以来的地壳运动趋势分析，对判断该区域的应力状态和地震大形势具有一定的参考意义。
By studying the evolution characteristics of the Earth’s deformation field in the North and South seismic belts and the eastern Qinghai-Tibet block over the past 20 years and its relationship with the seismic activity, it is found that the deformation of the land has both the spatial and temporal distribution heterogeneity, Similarity; Inheritance movement is the general trend of modern crustal movement, and the movement is wave-like, surging forward. During the crustal movement there exists a phase of regional strain energy accumulation and release adjustment, which may be the relative calm and active dynamic mechanism of seismic activity. The trend analysis of crustal movement since 1991 has certain reference value for judging the stress state and the earthquake situation in this area.
