为开拓航空电磁法的应用领域,1985年11月,物化探研究所航空物探室,在总结前人工作经验基础上,在河北省南宫地区,开展了航空电磁法寻找古河床淡水的科研试飞。本文介绍利用电磁场的区域特征和电磁响应特性,进行“水质填图”的尝试。通过对照南宫水库不同水质的电性分布图,可以看到这种尝试展示了该方法的实用前景。
In order to explore the field of application of aeronautical electromagnetism, in November 1985, the Aviation Geophysical Laboratory of Geophysical and Geochemical Exploration Institute conducted a scientific test flight to look for paleo-river freshwater in the Nangong region of Hebei Province on the basis of previous work experience. This article describes the use of regional characteristics of electromagnetic fields and electromagnetic response characteristics of “water quality mapping” attempt. By comparing the electrical distribution of different water quality of Nangong Reservoir, we can see that this attempt shows the practical prospect of this method.
