摘　　要：芙蓉峡是常山"国家地质公园"内一具独特地貌现象的山区河段——河床狭窄、谷坡陡峭、阶地宽广。该文从地貌、沉积、年代和构造四方面研究导致该现象的地貌事件过程、发生时间和发生原因等。结果显示:正是由于芳村溪袭夺金源溪上游及所引发的河流强烈下切,才形成芙蓉峡段地貌景观;这次河流袭夺发生的年代约在52.38-33.6 kaB.P.,可能与区域一NE向断裂的一次强烈活动有关。该研究成果有助于揭示公园的地学科学内涵,挖掘其地学旅游价值,指导当地地学科普旅游的开发。Furong Gorge in Changshan ncatonal geopark is a spectacular section with a special alluvial terrace （T2） in a mountainous area： extensive terrace plane and deeply incised valley. Based on the landform features in the upper and lower reaches around the section, and the comparison of the sediment characteristics of the terrace with those in adjacent rivers,it was found that it may be the fiver piracy which caused the formation of this special alluvial terrace in Furong Gorge Using the data collected in the field, the process,the time and the reason causing this river piracy has been further analyzed. The research result shows it may be 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 in NE direction in the region, which took place during 52.38--33. 6 kaB. P.. This research result can contribute to the enlarging of the tourism activities and promote tourism quality in the national geopark.
