摘　　要：由于地震资料的空间分辨率依赖于所分析位置与观测方向,而常规的分辨率定义仅局限于水平与垂直方向分辨能力,因此提出方向空间分辨率的概念,并推导出三维方向空间分辨率的一般公式。同时证明该公式与Vermeer推导的常速介质下的二维共炮检距的空间分辨率公式及马在田根据瑞雷分辨准则得到的分辨率表达式一致,说明文中所导出的方向空间分辨率公式正确且通用。Spatial resolution of seismic data is dependent on observing positions and directions,while the conventional definition of resolution is limited to horizontal and vertical resolution only.Therefore the concept of the directional spatial resolution is put forward in the paper,and a general formula of3 Ddirectional spatial resolution is deduced.Also,it is proved that the formula deduced in this paper is in consistent with the spatial resolution formula of 2Dcommon offset data in constant velocity medium derived by Vermeer and the resolution expression derived on the Rayleigh resolution criteria by Ma Zaitian.This may indicate the correctness and generality of the directional spatial resolution formula proposed in the paper.
