摘　　要：地球表层系统是地球系统中与人类关系最密切的部分,以地表系统为研究对象的地表过程研究越来越重要。将地球物理和大地测量等手段创新性地运用于地表过程的研究逐渐成为一个新的学科交叉发展方向。全球导航卫星系统(global navigation satellite system,GNSS)观测技术因其具有高精度、全天候、大范围和准实时的特点,被广泛应用于地表过程研究中。从长期地壳形变、地震周期形变、大气可降水量、荷载响应、岩浆及火山活动、滑坡监测和反射测量等方面简要介绍了GNSS技术在地表过程研究中的应用现状,并对未来发展方向进行了讨论。研究表明,鉴于GNSS在观测技术方面的优势,应加强其在地表过程研究中的应用。The earth surface system is the part of the earth system that is most closely related to human beings.The study of surface processes is becoming more and more important in earth system research.The innovative application of geophysics and geodesy to surface processes has gradually become a new interdisci‑plinary development direction.Global navigation satellite system(GNSS)observation technology is widely used in the study of surface processes because of its characteristics of high accuracy,all-weather,large range and quasi-real-time.In this paper,the application of GNSS technology in the study of surface pro‑cesses is briefly introduced from the aspects of long-term crustal deformation,coseismic and post-seismic deformation,atmospheric precipitable water,load response,magma and volcanic activity,landslide moni‑toring and reflection measurement,and then the future development is discussed.The advantages of GNSS in observation technology highlight the importance of GNSS in the earth surface processes research.
