摘要:

        采用pH=3.0、pH=4.5与对照pH=5.6的3种模拟酸雨淋溶土柱的方法,研究酸雨及含磷酸雨淋溶下合肥市郊水稻土中铅的释放特征与规律。结果表明:经过相当于1 980 mm降水量的淋溶后,铅释放量总体上表现为随着酸雨强度增加累积淋溶量也增加的现象。酸雨作用下,施磷量越多土壤中铅的淋失总量越大。在酸雨及施磷条件下,大兴地区黄褐土中Pb较义城地区水稻土中易于淋失。

Abstract:

      A soil leaching column experiment has been designed to investigate the release of Pb from paddy-soil in suburb of Hefei City under the influence of simulated acid rain.Compared with pH=5.6 rain, pH=3.0 and pH=4.5 acid rains were studied.Under leaching similar to 1,980 mm rainfall in the experiment, the release of Pb from the paddy-soil increases with the increasing of the acid rain strength.Promoting the release of Pb can be due to the enhancement of the phosphate quantity increased.The release amount of Pb differs with soil types.The leaching effect is more remarkable for soil sample from Daxing area than that from Yicheng area.

Key words: acid rain, paddy-soil, phosphorus, leachate
