摘　　要：通过Landsat 7 ETM+多光谱数字图像融合,对相山矿田的地表岩性、地貌景观及线环影像进行分析,共解译出NE向、NNW向、NWW向、SN向和EW向5组线性构造,这些线性构造具有多期次活动的特点,其中NE向线性构造F2在第四纪的活动,使相山矿田北西部相对于南东部陷落,形成北西、南东两个各具特色的影像区,南东影像区剥蚀程度较大,北西影像区更适合找矿。Based on data fusion between landset-7 ETM^＋ pan band and muhispectral bands and RGB synthesis, the authors analyzed the surface rock images and linear and ring images of Xiangshan area, and interpreted five linear fractures, namely NE, NNW, NWW, SN, and EW trending faults. The reactivation of NE trending fault No. F2 in Quaternary led to the subsidence of the northwestern part relative to the southeastern part in the Xiangshan ore field, forming two special image areas, namely the southeastern image area and the northwestern image area. The former is a archibole and has experienced a relative intense denudation, whereas the latter is a target area for uranium ore exploration.
