用土柱模拟4种加硒处理的土壤还原淋溶过程，研究了硒在土壤中的迁移和积累。结果表明，未加硒处理（土壤背景硒）的溶液中硒的迁移以有机硒占优势，Se(VI)及Se(IV)占的比例很小；土壤富里酸硒由上层向下层迁移。外源蛋白硒的处理的溶液中硒迁移为有机硒，部分外源硒以富里酸硒积累在下层土壤。外源Se(VI)和Se(IV)处理的溶液中硒迁移量只占加入量的0.2%和0.4%，硒迁移的主要形态前者为有机硒，后者为Se(IV)和有机硒。外源Se(VI)和Se(IV)的绝大部分以富里酸硒的形态积累于土壤，其积累量Se(VI)处理高于Se(IV)处理，上层土壤高于下层土壤。

Situation and problems of the China plastics packaging sector during the Eleventh Fiveyear Plan Period were introduced, of which the total output of plastics packaging materials was over 15 million tons, an annual average growth rate of more than 11 percentages. Some suggestions for its development during the Twelfth Five-year Plan Period were made, including its...
