摘　　要：地震走时层析成像是地球物理反演中的成熟方法之一,已在许多领域得到广泛应用,并取得了良好的效果。本文围绕地震走时层析成像GUI的快速实现,首先简要介绍了地震走时成像方法的原理和方法,并基于Matlab软件平台,利用GUI开发环境编写了二维横向非均匀地震走时层析成像图形用户界面(GUI),实现了方便快捷地反演地震测深资料的速度结构并以人机交互方式快捷灵活地将图像显示出来;结合实际观测资料处理结果表明,本文编制的GUI软件能够有效地实现地震走时层析成像结果的窗口化、图像化和快捷化。Seismic travel-time tomography is one of maior methods in geophysical inversion, has been widely used in many fields, and has achieved good results. The principle and method of seismic tomography method is briefly introduced in this paper; Based on Matlab software platform, GU1 software for seismic travel-time tomography in two-dimensional laterally inhomogeneous media is written by using the GUI tool GUIDE. The velocity structure can be inverted quickly and easily using seismic sounding data and the image of velocity structure can be displayed fast and flexibly in the GUI way. The actual observation data processing results show that the method and the software described herein is effective and feasible.
