砒砂岩泻溜侵蚀的坡向分异及其与气象因素的响应

Shuitu Baochi Xuebao
[目的] 泻溜作为砒砂岩区典型的重力侵蚀方式,已成为沟道内重要的粗砂物质来源,严重威胁流域生态安全,明确该地区侵蚀机理对黄河流域生态保护和高质量发展战略具有重要意义。[方法] 以内蒙古砒砂岩沟坡系统为研究对象,基于野外定位监测,利用三维激光扫描技术,分析不同坡向下沟坡侵蚀界面微地形变化与侵蚀特征的时空变化规律及其与气象要素之间的响应关系。[结果] (1)砒砂岩沟坡存在明显的泻溜侵蚀现象,且坡向分异较为明显。其中,阴坡平均侵蚀面积占研究区总面积的43.11%,阳坡平均侵蚀面积占研究区总面积的45.48 ...

不同坡形坡面径流流速时空分异特征研究

Shuitu Baochi Xuebao, 2007
通过室内模拟降雨试验分析了不同坡形坡面径流流速的时空分异特征,研究结果表明:同雨强、同坡度条件下,直线形坡的坡面流速最大,凸形坡的其次,凹形坡的最小,并且在同坡形条件下,坡面流速随雨强、坡度的增加而增加。另外,不同坡形坡面径流流速在空间上也存在一定的差异,坡面径流流速基本上沿着坡面向下逐渐增大,并且坡面上各段流速随坡度、雨强的增大而逐渐增大。
