摘要:
 为更加准确判识小流域地貌发育阶段，以黄土高原综合治理小流域——陕西省淳化县泥河沟流域和乾县枣子沟流域为例，分别应用盒分维方法和Horton分维方法进行水系分维值的计算，并利用面积高程积分和地貌信息熵进行验证。结果表明，泥河沟和枣子沟流域水系盒分维值分别为1.886和1.827。根据Strahler曲线积分值和地貌信息熵方法验证结果表明，盒分维方法计算的水系分维值对流域地貌发育阶段的判识更加准确、可靠；这2个流域地貌处于侵蚀发育阶段的壮龄期，其生态敏感性整体上处于较低水平，生态环境抗干扰能力增强并趋于更加稳定的状态。
Abstract:
 In order to identify the geomorphic evolution of small catchments accurately，two typical small catchments (Nihegou and Zaozigou,located in Chunhua and Qianxian,Shaanxi Province,respectively,) in which the projects of comprehensive management of small catchments on the Loess Plateau of China have been conducted.The fractal dimension values of the two catchment were calculated by the Box fractal method and the Horton fractal method,and the results were verified by using the methods of the area-elevation integral and geomorphic information entropy.The results showed that the box fractal dimension values of the drainage systems of Nihegou and Zaozigou catchments were 1.886 and 1.827,respectively.According to the results of Strahler curve integral and geomorphic information entropy methods，the Box fractal method was more accurate and reliable for identifying the geomorphic evolution of the catchments.In conclusion,the erosional development stage of the two catchments is in the adolescent period.The ecological sensitivity is generally at a low level，and the anti-interference ability of the ecological environment is enhanced and tends to be more stable.
