新疆荒漠与半荒漠土壤微量元素的土类分异与地域分布趋势

本文研究了新疆荒漠与半荒漠土壤微量元素的土类分异、地域分异及微量元素在土壤剖面中的分布,并对土壤样品的误差分布进行了估计。研究表明,除风沙土外,各土类间微量元素含量差异不大;北疆土壤中大部分元素含量高于南疆;山地土壤微量元素含量高于平原荒漠与半荒漠地区土壤;微量元素在土壤剖面中的分异不明显。

The Regional Distribution of Soil Trace Element Contents in Desert and Semi-desert Areas of Xinjiang Uighur Autonomous Region

In this paper, the authors studied the differences of soil trace element contents among soil types, regions as well as soil profiles. The error distribution of soil samples are also discussed. Results showed that no significant differences can be found among most soil types; contents of soil trace elements from north Xinjiang are higher than those from south Xinjiang. There are also no significant differences can be found in soil profiles for trace element contents.
