摘要
对塔里木沙漠公路沿线不同立地类型沙丘化学性质特征进行了初步研究 ,通过分析测定 ,结果表明 :沙漠公路沿线的沙丘上 ,盐分和养分含量均差异较小 ,但普遍较低 ,盐分中主要离子平均值均小于 0 .5 0 % ,总盐均值也仅为 1.0 4 % ,而有机质均值为 5 .36 g·kg-1;pH值均在 8～ 9之间 ,基本上维持了中性偏碱的特点。
This paper elementally studied the sand dune physical and chemical properties under different types of site by Taklarmakan desert highway.Through measuring and analysing,the results of testing the sand dune indicated: the difference of salt and nutrient content wasn't obvious,but salt and nutrient content were general skew little, big eight ions' average of salt content,except total salinity, was less than per 0.50, average of total salinity was only per 1.04,as yet average of organic matter was 5.36 g·kg^(-1); pH was 8 to 9 in between that basically maintained neutrality skew alkaline character.
