摘　　要：河流袭夺是第四纪地质与地貌学的重要问题,一直受到国内外学者的广泛关注。在山东沂源柴汶河上游,于晚更新世发生了一起河流袭夺事件,迄今还保存着典型而完整的河流袭夺地质遗迹。本文在实地调查基础上,结合高精度DEM数据,研究了该地区的典型河流袭夺地质遗迹资源类型、特征及成因,并利用层次分析法对河流袭夺地质遗迹资源进行了综合定量评价。结果表明,山东沂源柴汶河上游河流袭夺主要地质遗迹资源达到世界级1处、国家级4处、省级3处、地方级2处。该地河流袭夺地质遗迹资源的综合定量评价,对正确认识河流袭夺地貌演化、保护与开发地质遗迹资源、促进当地旅游经济发展等具有参考价值。River capture is an important issue in Quaternary geology and geomorphology,which has been widely concerned by scholars at home and abroad.In the upper reaches of the Chaiwen River in Yiyuan,Shandong,a river capture event occurred in the late Pleistocene,and the typical and complete river capture geological remains are still preserved.On the basis of field investigation and high precision DEM data,this paper studies the types,characteristics and causes of typical river capture geological relics resources in this area,and makes a comprehensive quantitative evaluation of river capture geological relics resources by using analytic hierarchy process.The results show that there are 1 world-class,4 national,3 provincial and 2 local level geological relics in the upper reaches of The Chaiwen River in Yiyuan,Shandong province.The comprehensive quantitative evaluation of the geological relics resources captured by rivers in this area has reference value for correctly understanding the evolution of the geomorphology captured by rivers,protecting and developing the geological relics resources,and promoting the development of local tourism economy.
