浅谈GPS在地质剖面测量中的应用及地质剖面绘制中的便捷方法

Application of GPS in geological section survey and convenient method for drawing geological section

为提高森林沼泽景观浅覆盖区地质剖面测量的精度和效率,本文以黑龙江省呼玛县早侏罗世正长花岗岩剖面测量为例,探讨利用GPS测量技术进行地质剖面测量的方法和流程。结果表明,利用GPS工具,通过室内数据准备-野外GPS数据采集-室内数据处理-剖面图的生成等流程,并结合SECTION软件及EXCEL软件,可以避免视野通透性差、测量路线障碍物多、地形复杂等许多不利因素,以较小的误差较快的速度实现地质剖面测量。

The Early Jurassic syenogranite section measurement in Huma, Heilongjiang is taken as an example to discuss the method and process of the geological section measurement using GPS technology to improve the accuracy and efficiency of the geological section survey in the shallow covering area of forest swamp. The results show that using GPS tool, through the process of indoor data preparation-field GPS data acquisition-indoor data processing-section generation, combining SECTION and EXCEL softwares, many unfavorable factors such as poor visual field permeability, obstacles in the measuring route and complex terrain can be avoided, and accurate and efficient geological section measurement can be achieved.
