| 中文摘要: |
| 近年来航空磁测工作逐步向大比例尺测量发展,但这能否让我们提高测量效果呢？本文以伊春森林覆盖区的航磁工作为例,通过1∶50000与1∶10000比例尺航磁测量数据处理结果的对比,发现大比例尺的航磁数据能够更好的突出细节。相比之下,小比例尺数据通过处理之后仍不能得到大比例尺数据所能得到的全部信息。大比例尺数据经过处理后能够得到更好的地质解释效果,但在实际勘查及找矿工作中,需要综合考虑成本与目标体特征,选择合适的测量比例尺。 |
| 英文摘要: |
| In recent years, the work of aeromagnetic survey has gradually developed to large-scale measurement, but can this make us improve the measurement effect? Taking the aeromagnetic work in Yichun forest cover area as an example, through the comparison of the data processing results of 1∶50000 scale and 1∶10000 scale aeromagnetic survey, it is found that the large scale aeromagnetic data can better highlight the details. In contrast, the small-scale data can not get all the information that the large-scale data can get after processing. Large scale can get better geological interpretation effect after processing, but in the actual exploration and prospecting work, it is necessary to comprehensively consider the cost and target characteristics, and select the appropriate measurement scale. |
