摘要

基于西北干旱地区典型土遗址盐渍带盐分野外观测和定性分析结果，初步总结了土遗址盐渍土带特征并阐释了风蚀损耗效应的概念；通过对掺入不同含量2种盐渍带常见盐分Na2SO4和NaCl，并经历干湿循环的遗址土重塑样的风洞模拟试验和微结构分析试验，揭示了盐渍带中常见盐分发生的盐渍过程会对遗址土抗风蚀能力产生显著的影响；并通过统计学分析方法证实了试样的风蚀速率与有关孔隙的部分微结构特征参数之间存在着良好的对应关系；最后结合定性分析和试验研究结果，从微观角度对土遗址盐渍带土的风蚀损耗机制进行了初步的讨论。

Abstract

Based on salinity field observations and qualitative analysis results at salinization belt of the typical earthen ruins in the research area

the paper summarizes the characteristics of earthen ruins with saline soil and generates a brief concept of aeolian erosion ullage effect. And then

on the basis of wind tunnel simulation experiment and microstructure analysis results of reconstituted samples going through dry-wet circulation after being mixed with different content of common salts Na2SO4 and NaCl

it reveals that the saline process of those salts have significant impact on anti-erosion ability of the site

and a good correlation existing between microstructure characteristics parameters of pore and wind erosion rate of the samples under saline process is also proved by statistical analysis method. Finally

with a combination of the qualitative analysis and the experimental results

depletion mechanism of the effect of aeolian erosion ullage at the salinization belt of earthen ruins is preliminarily discussed from a microcosmic standpoint.
