The embodiment of the invention discloses a sampling method and device. Sampling point distribution data of a target area in a seismic acquisition and observation system are provided, the sampling point distribution data meet complete sampling conditions, and a distance between adjacent two sampling points in the target area is included in the sampling point distribution data; according to the point distance, the target area is divided to multiple quadrat subareas, and each quadrat subarea contains multiple sampling points; and according to a specified undersampling factor, multiple sampling points in the quadrat subarea are subjected to random sampling to obtain undersampling point distribution data of the target area. According to the technical scheme provided in the embodiment of the invention, the undersampling point distribution data can meet randomness requirements, and a condition in which the sampling points are over dense or over scattered is avoided. 本申请实施例公开了种采样方法及装置。所述方法提供有目标区域的地震采集观测系统中采样点分布数据；其中
