| 摘 要： | 根据区域重磁场的特点,利用其水平一导峰谷值线可确定异常体的线性构造,垂向二阶导数可确定异常体的环形构造的基本原理,在计算机上自动完成重磁数据处理及成图;并基于GIS"空间分析"功能对图形进行模式识别;实现区域重磁构造的自动提取与空间信息的自动集成.通过对我国东昆仑1:100万重力资料的实际应用,表明其结果具有实用性,其信息集成技术可用于改造以往计算机成图并借助透明纸叠置的人工重磁资料解释工作模式.

| Abstract: | According to the characteristics of gravity and magnetic regional field,the gravity and magntic data can be processed and drawn automatically on the computer with the theory,which includes concluding linear structure of the anomaly body by using the horizontal first derivative and ring structure of the anomaly body by using the vertical second derivative.Then,graphs are identified with the pattern based on the spatial analysis of GIS.The automatic extracting the gravity and magntic structure and integrating the spatial information has been realized in a region.It has been used in interpreting 1:1,000,000 gravity data in the east of KunLun,China.The result shows that it is useful.The technology of information integration can be used to change the old working mode,which explains data by hand using transparent papers overlay. |
