系统研究了西天山地区水系沉积物在不同粒级的主要元素分布特征和风积黄土的粒级、元素含量分布特点。应用稀土配分模式的方法证实了水系沉积物中有风积黄土掺入。同时发现了风积黄土掺入对水系沉积物中元素含量产生了干扰作用，此种干扰作用随着采样粒级的变化而变化。通过对比，认为水系沉积物采样应该大于80目才能有效避免风积黄土的干扰，该研究为制定西天山地区水系沉积物测量的方法技术提供了重要依据。

The article systematically studied the primary elements distribution of different grades of stream sediments as well as the grain size and element content characteristics of aeolian loess. The REE partitioning method has confirmed the existence of aeolian loess in stream sediments, what′s more,the involvement has disturbed the content of elements in the sediments,and the interference varies as the sample particle size changes.The study supply important gist for the method and technique of stream sediment measuring,and suggest that the best sample grade should be greater than 80 mesh to avoid the interference of aeolian loess.
