摘要
Abstract
It adopted the saturated-unsaturated layered soil column experiment and its numerical simulation to study the variation of copper migra-tion depth with time and the influence factors. The results show that early in the experiment,negative pressure in the vadose zone can lead to soil water redistribution:the moisture content of unsaturated soil increases in a small degree and that of upper unsaturated soil reduces obviously,but recovers soon. Water negative pressure has a little influence to the copper migration. Migration rate of copper will decrease with the increase of soil depth. Adsorption-precipitation effect is the main factor. That copper reaches the depth of 20 cm,35 cm,45 cm,52. 5 cm,66. 7 cm and 70 cm at the time of 60 d,110 d,160 d,1 y,3 y and 5 y,which can be used for dealing with copper polluting of soil and underground water.关键词
