摘　　要：为掌握长平井田断层发育复杂程度,通过以相似维为特征值的分形理论对其进行了定量评价和分区。同时,通过整理长平井田所在区域地质演化史资料,探讨了长平井田断层形成演化机制。研究表明:断层在井田东部较西部更为发育,北部较南部更为发育。复杂区集中于井田北部中段,而井田西南部为断层发育简单区。印支运动和燕山运动使长平井田分别受到近SN向和SE—NW向挤压应力场作用而形成构造线呈EW向和NE—NNE向的逆冲断层带,后经喜山运动NW—SE向拉伸作用,先期逆冲断层发生构造反转,促成现今由正断层控制的井田构造格局。In order to grasp the complexity of fault development in Changping mine field, the fractal theory with similar dimensions as ei-genvalue was ued to quantitatively evaluate and partition it. At the same time, the evolution mechanism of the fault was discussed through the data of geologic evolution history of Changping mine field. The results show that the faults were more development in the eastthan the west and more development in the north than the south. The complex area was concentrated in the middle of the northern,and the southwest of the mine was a simple area for fault development. The Indosinian movement and the Yanshanian movement made theChangping mine field face the nearly SNand SE-NW trending compressive stress fields to formththe NW-SE trending stretching during the Himalayan movement,pre-thrust tectonic inversed,and facilitated the structure of mine fieldcontrolled by normal faults. The results can provide geological basis for late exploration and forecast of faults in mine field.
