| 摘 要： | 在大量野外实地考察的基础上，研究了济南龙洞景区的河流袭夺现象．阐明了河流袭夺的形态特征，并根据地貌面与沉积证据判定了河流袭夺发生的时代，从而揭示了龙洞景区深谷与陡崖的形成过程．研究表明：龙洞景区河流袭夺发生于第四纪初期，是研究区造景地貌形成的主要外营力．其成因不仅与河流侵蚀能力的差异有关，还与流域地貌演进阶段、区域岩性及构造特征、气候及海平面变化等因素密切关联．

| Abstract: | Based on the data of field investigation, the river capture between Daxin River and Quanlu River in Dragon Cave Area in Jinan City of Shandong Province was studied in this paper. The landform characters and sediment evidences are also proposed. It indicated that the river capture was formed in Eopleistocene. The different erosive abilities of different rivers, the regional rock characters and tectonic features, the stage of drainage landform evolution, climate and sea level changing are all the formation causes of the river capture. It is the river capture that has caused the deep valley and sheer precipice in the Dragon Cave Area. |
