The Buddhist temple site at the ancient city of Beiting,dating to the Khoco Uighur period,is located in Jimsar County in Xinjiang.There are various kinds of deterioration in the relics,such as the slipping of adobe structure,partial collapse,severe weathering of the surface and salt damage.The changes and development of salt damage further exacerbated the extension of both partial collapse and surface weathering.This paper presents a study on the law of salt distribution by measuring samples with the technology of a high-density resistivity instrument and infrared thermal imager.The results show that salts are mainly distributed at the bottom of the walls,and the proportion of salts diminishes gradually from the bottom to top in the wall.The application of the high-density resistivity instrument and infrared thermal imager in earthen sites plays an important role in the in-vestigation of earthen sites and non-destructive testing analysis.
