     Based on the division of water systems in the Xiaoqinling gold ore district, the authors studied the concentrations and distribution of seven kinds of heavy metals. On such a basis, the factors affecting the occurrence and migration of heavy metals in stream sediments were revealed. Some conclusions have been reached: 1) in the light of regional distribution, the heavy metal concentrations of the stream sediments at the northern foot of the Xiaoqinling Mountains are generally higher than those at the southern foot; and 2) in the light of the differences in element content in the stream sediments of the Xiaoqinling gold ore district, Pb has the highest content and most remarkably deviates from the background value, followed by Hg.
