摘　　要：2008年5月12日汶川地震(M_S8.0)发生后,各部门组织开展了一系列汶川地震相关的地学研究,包括国家科技专项"汶川地震断裂带科学钻探"项目.经过十年的持续探究,在地震地质、震源物理、地震实验、地震动力学、深部地球物理和长期监测等方面研究取得了一系列重大突破与重要成果.在汶川地震十周年之际,《地球物理学报》集中在2018年第5期刊发39篇文章作为汶川地震十周年专辑,专辑涵盖了汶川地震和九寨沟地震断层作用与动力学过程以及相关领域的一批最新研究成果.这些工作涉及汶川地震断层作用、地震参数及地震动力学数值模拟、汶川地震前地震活动性与多参数异常、晚第四纪构造与地震活动及其地表作用、青藏高原东部壳幔结构与龙门山断裂带深部构造和九寨沟地震等六方面的研究.本文将从这六个研究方向简要介绍收入本专辑论文的研究工作,呈现地震断层作用及动力学过程等研究成果,为深入认识大地震孕育和发生过程提供重要的基础.After the May 12 th 2008 Wenchuan earthquake（MS8.0）,a series of geoscience studieson the Wenchuan earthquake have been funded by different government departments including the＂Wenchuan earthquake Fault Scientific Drilling＂of the National Science and Technology Planning Project.After ten years continuous studies,a series of significant breakthroughs and important achievements in the seismic geology,seismic physics,seismic experiment,seismic dynamics,deep geophysics,and earthquake long-term monitoring etc.have been made.Therefore,on the 10 th anniversary of the Wenchuan earthquake,Chinese Journal of Geophysics will publish 39 papers in the 2018 No.5 as the special issue of the Wenchuan earthquake.This special issue expands greatly on the latest achievements of faulting and dynamic processes as well as other fields associated with the Wenchuan and Jiuzhaigou earthquakes.The volume covers the following six subjects：faulting processes,seismic parameters and numerical simulations of seismic dynamics,seismic activities before the earthquake and multi-parameter anomalies,tectonic and seismic activities in the Late Quaternary and their surface processes,crust-mantle structure of the eastern Tibetan Plateau and deep structure of the Longmen Shan thrust belt,and Jiuzhaigou earthquake etc..This paper aims to introduce briefly the study work of each paper according to the six subjects,and to present the achievements on faulting and dynamic processes,in order to provide significant basic data for the further understanding of the seismogenic and seismic processes.
