腾格里沙漠穿沙公路沿线盐渍土分布特征

Distribution Characteristics of Desert-crossing Highway in Tengger Desert

通古勒格淖尔至额尔克哈什哈公路(蒙甘界)全线穿越腾格里沙漠,穿越里程约200km,公路线路通过湖盆地带,这些湖盆地带处于沙漠腹地地势低洼处,主要为盐渍土地基。文章通过现场调查、取样与室内试验对公路沿线盐渍土的形成原因及分布特征进行了分析,得出了该路段沿线盐渍土分布特征。

Tonggulege Nur to Elk Hashha（the boundary between Inner Mongolia and Gansu） goes through the Tengger Desert, and the crossing mileage is about 200 kilometers. The highway route inevitably passes through the lake basin, which is located in the low - lying areas of the desert, and these lake basins are mainly saline soil. In this paper, the causes and distribution characteristics of saline soil along the highway were analyzed by field investigation, sampling and indoor experiment, and the distribution characteristics of saline soil along the line were obtained.
