摘　　要：京西隆恩寺刀背岭是座落于北京小西山一道北东走向、陡峭如墙的小山岭。从地质构造、区域地层、岩性对比和地貌走向等方面,探究了刀背岭的构造成因:在燕山运动末期,地下岩浆沿着燕山运动的构造裂隙侵入近地表时,形成流塑体并挤向地面形成岩墙;由于形成年代相对较新,岩墙岩性坚硬,抗风化能力极强,形成刀背岭山脊。对刀背岭构造成因的研究,希望能为类似的地形地貌形成原因研究提供有益的参考。The Daobeiling of Jingxi Long'en Temple in the Beijing Xiaoxishan Mountain is a small mountain range that runs northeast and is as steep as a wall. This paper explores the structural genesis of Daobeiling through geological structure, regional stratigraphy, lithology comparison, and geomorphologic trend. The study shows, in the late stage of the Yanshan Movement, underground magma intruded near the surface along the structural fissures of the Yanshan Movement, forming flow plastic bodies and squeezing towards the ground to form rock walls. Due to its relatively new formation age, the rock wall has a hard lithology and strong resistance to weathering, forming the ridge of Daobeiling. The study on the genesis of the Daobeiling structure hopes to provide useful references for the research on the formation reasons of similar terrain and landforms.
