摘　　要：针对沙漠地区地表覆盖厚,且普遍有一层盐碱壳覆盖,各种地质现象无法从地表发现的情况,选用高频大地电磁法仪器对该地区进行了勘探,结果显示在不影响数据质量的前提下,提高了施工效率,对地下地质体电阻率成像分辨率高,位置准确。Since the surface area covered by thick desert, and generally covered with a layer of saline shell, various geological phenomena cannot be found from the surface. We chose the high-frequency magnetotelluric instrument in the exploration work, and the results showed that under the same data quality requirement this method improved field work efficiency, and had high resolution for subsurface geological body resistivity imaging, also had accurate positioning.
