本文对广西柳州、华北平原和湖南雪峰山、江苏海州、甘肃白银厂等地以不同比例尺、不同灵敏度仪器所取得的航磁测量结果进行了对比分析，认为提高航磁测量精度（从低精度到中高精度）、加大比例尺后能够取得较为丰富、详尽的磁场信息，这对研究地质构造、提高普查找矿能力将起到重要的作用。 In this paper, we compare the aeromagnetic measurements obtained from different scales and different sensitivity instruments in Liuzhou of North China, North China Plain and Xuefeng Mountain of Hunan Province, Haizhou of Jiangsu Province and Baiyin Plant of Gansu Province, To medium and high precision). After expanding the scale, more abundant and detailed magnetic field information can be obtained, which will play an important role in studying geological structure and improving census prospecting ability.
