窟野河河流阶地的相关分析

Correlation Analysis on River Terraces of Kuye River

对窟野河河流各级阶地基座顶面高差相关分析的结果表明,各级阶地所反映的新构造运动的幅度变化在沿河方向上分段具有开口向下,对称轴铅直的二次抛物线特性,其性质、幅度和中心位置具有明显的继承性。各次抬升幅度的区域差别随时间呈阻尼式减小。同时,新构造运动的区域差异与流域现代土壤侵蚀强度的区域分异基本吻合,即抬升幅度大的地区土壤侵蚀强度亦大。

In this paper,the neotectonics of the Kuye River basin have been reconstructed based on the extensive field investigation and correlation analysis.These analytical results show that the neotectonics of the Kuye River basin have remarkable characteristics of the divided quadratic parabola as well as vibration and inheri- ty and synchronization along the channel.Its uplifting extents,speeds,centres,extreme value and gradients have been gained.The more intense amplitudes of the neotectonics are,the more serious the soil erosion will be.
