| 摘 要： | 北京大石河南岸从上游至下游依次分布鸡毛洞、银狐洞、石花洞、清风洞和孔水洞，由一条地下暗河将其连为一体，称为石花洞系。石花洞系为多层溶洞，可分为上下8层，即洞外山顶穿洞（唐县期）和洞穴上下7层。多层溶洞的每一层形成于岩溶水的水平流动带，新近纪以来，随着北京西山间歇性隆升，形成上下不同海拔高度的8层溶洞，可以和北京西山永定河的8级阶地对比，也可以和G．B．Barbour划分的8次华北地文期对比。石花洞的8层溶洞显示北京西山的8次抬升。

| Abstract: | Connected by an underground river, the Shihua Karst Cave System is along the south bank of Dashi River, which is composed of Jimao Cave, Yinhu Cave, Shihua Cave, Qingfeng Cave and Kongshui Cave from upstream to downstream. The karst caves sum up to 8 layers up to down. Each layer is formed on karst water table. Since Neogene, it has formed 8-layered caves at various elevations with the Neotectonic Movement of Beijing Western Mountains. It could be correlated with Physiographic Stages of North China and terraces of Yongding River; namely the 8-layered karst caves record 8-staged upwelling of Beijing Western Mountain. |
