大巴山泥石流侵蚀作用及防治对策研究

Shuitu Baochi Xuebao, 1993
通过对大巴山泥石流形成和发育过程的研究，从侵蚀机制的角度，将其分为坡面侵蚀，沟谷侵蚀，复合侵蚀三种基本的侵蚀类型，并进一步分析了不同影响因素在各类泥石流发育中所起的作用，认为：坡面侵蚀型泥石流的发育与植被关系最密切；沟谷侵蚀型泥石流的发育对暴雨的依赖性最大；复合侵蚀型泥石流的发育与沟岸的不稳定有很大关系。最后，针对性地提出了大巴山区各类泥石流的防治重点。

聚酰亚胺填埋双沟脊型器件沟道的制作方法

一种聚酰亚胺填埋双沟脊型器件沟道的制作方法，包括如下步骤：步骤1：在衬底的表面依次生长有源层和限制层，作为器件的基本结构；步骤2：在限制层的表面制作光刻图形；步骤3：光刻，在限制层的表面刻蚀出双沟脊型结构，刻蚀深度到达有源层的表面；步骤4：在双沟脊型结构内及限制层的表面涂聚酰亚胺介质层，预固化；步骤5：在聚酰亚胺介质层的表面涂光刻胶，烘干；步骤6：曝光，显影去掉双沟脊型结构上的及限制层表面的聚酰亚胺介质层，固化 ...

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 ...
