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 ...
