摘　　要：以甘肃省天水市麦积区花牛镇花牛村苹果种植区的某一果园为研究基地,通过人工干预该种植地区土壤中微量金属元素含量的方法,将Cd、Pb、Hg三种有害金属元素添加到土壤中,然后每隔15天对土壤中各有害元素含量进行了测定来考察有害金属元素在果树种植土壤中的迁移规律。结果表明,Cd、Pb和Hg有害金属元素随着植株生长过程都会迁移到果实当中,最终会影响人类的身体健康,而且迁移速率随着时间的延长有增大的趋势。The soil of apple planting area in Tianshui, Gansu province michael plot huaniu town village as the research object, through manual intervention motion, Cd, Pb, Hg, three kinds of harmful metallic element were added to the soil to change trace element contents.Every 15 days the harmful element content in soil was determined, inspected the transferring disciplinarian of harmful metal elements in fruit trees planted in the soil.The results showed that with the change of time, elements of Cd, Pb and Hg in soil were migrated, and soil was contaminated, it ultimately impacted on human health and safety, and migration rate over time had a tendency to increase.
