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.
