摘　　要：和传统欧拉反褶积相比,重力梯度数据联合欧拉反褶积具有更高的计算精度和反演分辨率。为了消除计算产生的发散解,在应用中须使用不同的筛选方法,使得计算流程变得相对繁琐。可见提供有效的筛选方法与开发一个易用的可视化软件有利于提高该方法的准确性、便捷性和使用效果。因此,本文提出基于相关系数边界识别约束的重力梯度数据联合欧拉反褶积,并依据界面直观、功能实用、代码简洁的设计原则,针对算法流程与功能需求,利用Python语言及其函数库设计了一种支持数据/文件管理、二/三维可视化、边界识别、重力梯度数据联合欧拉反褶积等功能的软件系统。通过理论模型与实测数据试验,验证了计算的准确性和软件的实用性,设计的软件系统能够提高应用效果。Compared with Euler deconvolution, joint Euler deconvolution of multi-component gravity gradient data features higher calculation accuracy and inversion resolution. To eliminate the divergent solutions of calculation, different screening methods must be used in the application of joint Euler deconvolution of multi-component gravity gradient data, making the calculation process cumbersome. It is evident that effective screening methods and developing a piece of easy-to-use and visual software can improve the accuracy, convenience, and effects of the joint Euler deconvolution of multi-component gravity gradient data. Therefore, this study proposed the joint Euler deconvolution of gravity gradient data with the constraint of edge detection based on correlation coefficients. Moreover, on the design principles of the intuitive interfaces, practical functions, and concise codes, this study designed a software system with functions such as data/file management, two-dimensional/three-dimensional visualization, edge detection, and joint Euler deconvolution of multi-component gravity gradient data using Python language and its function library to meet the requirements of algorithm flow and functions. The accuracy of calculations and the practicability of the software have been verified through a theoretical model and tests of measured data, proving that the software designed in this study can improve the application effects.
