中文摘要：
河北省天桂山地区的喀斯特洞穴集中分布在早古生代寒武纪-奥陶纪碳酸盐岩地层中,多沿NW-SE、NE-SW和近S-N断裂发育。受第四纪间歇性构造抬升影响,溶洞具有成层分布特点。以溶洞景观类型为基础,将该区溶洞分为侵蚀型和堆积型两大类,分别以银河洞和珍珠洞为代表,前者多发育各种窝穴、流痕、边槽等侵蚀及坍塌景观,后者则发育各种化学堆积景观。研究溶洞景观成因类型及特征对于天桂山旅游资源的合理开发和保护具有重要指导意义。
英文摘要：
The caves in Tianguishan of Hebei Provence distribute in Cambrian and Ordovician carbonate rocks,and develop following NW-SE,NE-SW and S-N fractures.Due to the influence of intermittent tectonic uplift in Quaternary Period,the caves have the characteristics of layer distribution.Based on the discussion to sorts of the cave landscape,the caves are divided into two types of corrasive caves and accumulation caves,and Galaxy Karst cave and Pearl Karst cave are taken as example respectively.The solutional small forms including pocket type and orientational flute type etc.developed in the corrasive caves are very typically and varied.There is a lot of chemical sediment landscapes in the accumulation caves.To study the genetic sorts and features of the typical karst caves is important for tourist resources development and conservation in Tianguishan area.
