Tectonic and geomorphic changes of Zhangshiyan tourism landforms,Hebei Province
河北省嶂石岩风景区的造景地貌及其演化

Zhangshiyan of Hebei Province is a national tourist scenic spot. It has many strange, perilous, graceful and beautiful geomorphic types. They were formed since 37 MaB.P., and experienced three major geomorphic cycles during the Early Tertiary, the Late Tertiary and the Quaternary eras and left many geomorphic types of different evolutional stages of infancy, youth, maturity and old age. The major evolution patterns were strong tectonic uplift, collapse, side and headward erosion, and raze. The rocks of sandstone and limestone also played an important role in landform evolution. The predominant geomorphic evolution situation in future will still be infancy stage to youth stage for a long period of time. But as tourism developed, the strange and beautiful scenic spots of maturity stage development level are more liable to be destroyed by tourists. So, how to prevent these geomorphic types from being destroyed is a pressing issue.
