摘　　要：本文基于数字高程模型和空间分析技术,对山东沂源柴汶河袭夺地区的流域地貌进行研究,划分流域地貌的发育阶段。分别计算了柴汶河源头——恶沟和沂河源头——大张庄河流域的水系分形维数、面积-高程积分和地貌信息熵并划分流域地貌发育阶段,认为面积-高程积分和地貌信息熵值的划分结果较为准确。恶沟流域处于流域地貌发育的壮年期,大张庄河流域处于老年期;河流袭夺事件使恶沟(袭夺河)侵蚀能力增强,大张庄河(被夺河)侵蚀能力减弱。Based on the digital elevation model and the spatial analysis techniques,in this paper,we studied the watershed landforms in the area of Chaiwen River in Yiyuan,Shandong Province,and divided the developing stages of the watershed landforms.Egou and Dazhangzhuang River are the head of Chaiwen River and Yihe River,respectively.Their water system fractal dimension,hypsometric index and geomorphic information entropy were calculated,and the geomorphologic development stages were divided.It is believed that the result of hypsometric index and geomorphic information entropy is more correct.The Egou River basin is now at the mature stage of geomorphologic development,and the Dazhangzhuang River basin is now at the old stage.River capture event enhanced the erosion ability of Egou and weakened the erosion ability of Dazhangzhuang River.
