摘要: 在地貌信息熵计算方法和涵义讨论的基础上,计算了秦岭-黄淮平原交界带面积大于100km2各流域的地貌信息熵值,进而分析了秦岭-黄淮平原交界带的地貌演化阶段。得出以下结论:该区地貌演化处于壮年期和老年期的过渡阶段;各流域坡面形状多为下凹形为主,但山地整体的坡面形状近于直线形。

Abstract: Based on the discussion of the calculation methods and the implications of the geomorphic information entropy,this paper calculated the numerical values of the geomophic information entropy of each drainage basin (area≥100km2) in the transitional region of Qinling mountains and Huang-Huai Plain,analysed their geomorphic evolution periods,and reached the following conclusions:the geomorphic evolution stage of the transitional region of Qinling mountains and Huang-Huai Plain is in the transitional period between mature stage and old stage;the slope shapes of the most of the drainage basins are concave,but the whole shape of the transitional region of Qinling mountains and Huang-Huai Plain is roughly straight line.
