摘要/Abstract

摘要： 芙蓉峡是常山国家地质公园内一具独特地貌景观的山区河段-狭窄的河床、陡峭的谷坡和宽广的阶地.本文从地貌、沉积、年代和构造四方面对导致该景观的地貌事件，从事件过程、事件发生时间和事件发生原因等方面进行了初步调查研究.研究结果显示：正是由于芳村溪袭夺了金源溪上游及所引发的河流强烈下切，才形成了芙蓉峡段这种地貌景观；这次河流袭夺发生的年代估计在52.38~33.6 ka B.P.期间，发生的原因可能与区域一NE向断裂在这期间的一次强烈活动有关.

Abstract: Furong Gorge in Changshan National Geopark is a spectacular section with a special alluvial terrace. Based on the sediment characteristics, the landform and the datings on some sediment samples, this paper analyzed the process, the time and the reason of the river piracy which caused such phenomena. The result showed it was the Fangcun River that pirated the Furong River which originally flowed into Jinyuan River. This geomorphologic event may be the result of the movement of the faults with NE and NNW stikes in the region, which took place during 52.38~33.6 ka B.P.

Key words: national geopark, Furong Gorge, river piracy, Changshan County, national geopark, Furong Gorge, river piracy
