| 摘 要： | 研究了模拟酸雨pH值,阴、阳离子浓度及比例对成都市典型土壤镉释放的影响.结果表明,研究区水稻土和黄壤经酸雨淋滤都表现出以下规律:(1)土壤中的镉在高酸度条件下极易活化;(2)增加酸雨中阴、阳离子浓度,土壤镉的释放量相应增大;(3)SO42-/NO3-中NO3-的比例提高时,土壤镉的释放量增大.

| Abstract: | This paper studies the impact of simulated acid rain with different pH,concentration and ratios of anions and cations on the cadmium release of typical soils in Chengdu.The results show that for paddy soil and zheltozem in research area,there are similar laws after leaching,such as(1) soil cadmium is readily mobilized under higher pH value of acid rain;(2) the release of soil cadmium increases with increasing of the concentration of anions and cations;and(3) when the proportion of NO 3-is elevated,the release of soil cadmium will occur. |
