摘　　要：云台山世界地质公园位于太行山的南部边缘,源于太行山腹地的一系列河流,切穿太行峰脊,形成众多山高谷深瀑水飞溅的峡谷群,成为南太行山旅游的核心地质遗迹景观。峡谷中河流阶地发育,通过对云台山及周边地区九条典型峡谷中河流阶地发育特征研究,探讨了河谷的发育历史;以及该地区不同时期的气候变化、新构造运动的性质和幅度,认为六级河流阶地在太行山河谷内普遍发育;但由于第四纪是强烈切割时期,所以这些河流阶地也大部分被剥蚀掉,仅在部分地区还不同程度残留有六级河流阶地的产物。Yuntaishan Geopark is located in the southern edge of the Taihang Mountains,originating from series of rivers of the hinterland of Mt.Taihang and cutting through the Taihang peak ridge.It has many groups of canyons with high mountains and deep valleys,and has become the core geological heritage landscape of the tourism in Southern Taihang.River terraces develop in the Taihang canyons,the development history of the valleys through researching on the developmental characteristics of nine typical river terraces in Yuntaishan and its surrounding areas are discussed.Moreover,it also probes into the climate changes in the region in different periods,as well as the nature and scope of the new tectonic movement.It finds that sixth-class river terraces widely developed in the valleys of Taihang Mountain,but most of them have been eroded away due to the strong cutting in Quaternary period.Consequently,products of sixth-class river terraces can only be found in a few areas.
