MD region belongs to mountainous area and has complex near-surface conditions. Therefore, the shooting and receiving conditions in the area is poor, and the seismic data has low signal-to-noise ratio. In order to obtain high-quality raw seismic data, we carried out field acquisition in dry season and rainy season respectively. By contrasting and analyzing the single-shot records and stack profiles obtained in the two seasons, we concluded that the quality of the seismic data acquired in dry season is better. The research result provides a good reference for the follow-up of seismic data acquisition in this region and similar regions.%MD地区属山区,近地表复杂多变,激发及接收条件差,地震资料信噪比低.为了获得较高品质的原始地震资料,分别在干季和雨季进行了野外资料对比采集；通过对不同季节施工的单炮记录和叠加剖面进行对比分析,认为在MD地区干季施工的地震资料品质要好于雨季施工的地震资料品质.研究结果对于该区后续地震采集及类似地区地震采集具有很好的借鉴意义.
