摘要
地球物理资料综合处理与解释在油气、煤田、矿物勘探、水文分析、水文工程与环境评价中有重要应用．然而，目前的（位场）地球物理处理与解释可视化程度低，无法利用其它资料有效的约束、关联分析与综合快速解释．虽然地理信息系统（GIS）是目前综合多种资料，进行空间处理、分析，提供决策支持的强有力工具，但是，GIS是为一般地理问题分析定制的，缺少综合地球物理处理解释的工具．本文给出了解决上述问题的，用组件对象模型（COM）实现的软件包-ArcGeophysics．在ArcGeophysics中，实现了勘探数据的有效管理，空间统计分析，地球物理（正演、反演），地球化学与遥感处理、分析、解释与可视化，信息集成与勘探靶区预测等功能．特别需要指出的是：（1）ArcGeophysics无缝地结合了ArcObiect（ArcGIS，ESRI），也就继承了当前国际上占主导地位的GIS软件包中所有的GIS功能；（2）ArcGeophysics是建立在COM基础之上，任何支持COM的应用环境（如MSOffice），编程环境（如MS Visual Studio（．Net），Borland Delphi等都可以调用这些功能（相当于通用开发工具包）；（3）ArcGeophysics对地球物理资料的处理解释结合了非线性系统、多尺度分析与多维分形理论．本文不仅给出了各向异性奇异性的应用实例，而且还给出了位场在Fourier空间处理分数维导数，以及在余弦变换空间多维分形模型（C—SA）．本文应用加拿大NovaScotia省南半部的地球物理、地球化学、地质与成矿资料进行了试算，得到了理想的结果，文中图2～图5均直接出之ArcGeophysics的输出．
The integrated processing and interpretation of applied geophysics has been widely used in the oil ＆ gas, coal bed, and mineral explorations, hydrogeology study ＆ hydrogeology engineering, and environmental assessment. However, the visualization and constraint modeling and inversion of geophysics with other available data are limited due to no suitable tool is developed for this purpose. The current GIS software is not suitable because none of them are designed and implemented for it, though the framework of GIS is very suitable for solving it. A Component Object Model （COM） based extension of ArcGIS-ArcGeophysics, is implemented for this task and presented in this paper. In the ArcGeophysics, there are visualization, integration and target evaluation models for data management, spatial statistics, geophysical forward modeling and inversion, geochemical analyzing, and remotely sensed data processing. It is valued to noted that： （1） ArGeophysics has been seamlessly integrated with the most popular and powerful GIS system-ArcGIS and since it inherited all the functions of this GIS system; （2） ArcGeophysics is a series of COM objects, any COM enabled system, such as MS office, or development environment could, such as VC＋＋ , access these functions;（3） ArcGeophysics is characterized with new technologies, such as nonlinear dynamics, multiple scaling, and multifractal theries, for example, the anisotropic singularity, Cosine domain multifractal filtering, Fourier domain fractional derivatives are analyzed. The southern part data of Nova Scotia, Canada had been processed. The results are excellent compared with known geology, mineral deposits and occurrences information. The Figs. 2～5 are directly from the output of ArcGeophysics.
