Study on the river piracy in Furong Gorge in Changshan National Geopark,Zhejiang Province;
浙江常山国家地质公园芙蓉峡河段河流袭夺现象研究
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 river piracy which caused the formation of this special alluvial terrace in Furong Gorge.
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。
