摘要
本文按时段和随机采集了三峡库区降雨径流水体样品，测定了水体中Ｃｕ、Ｍｎ、Ｎｉ、Ｚｎ、Ｐｂ含量，统计结果表明：Ｍｎ、Ｚｎ、Ｐｂ在径流水体中的含量趋于平均，变异系数较小。随产流时间的变化。
Rainfall runoff samples were collected by time duration at random.The contents of Cu,Mn,Ni,Zn and Pb in the water samples were determuned.The statistical result shows that Mn,Zn and Pb cotents are nearly equal to the average value with small variation coefficients.No obvious changing regulation of those 5elements in the water body with the change of runoff time.
