摘要: 我们在河南省117个县(市)内采集了913个土样,并对所有样品进行了可溶态稀土总量测定,对300个样品做了氧化稀土总量测定,对其中典型剖面做了单一稀土元素的测定。初步揭示了本省土壤中稀土元素分布规律与宏观环境的关系;初步摸清它们在地球化学过程中迁移、累积的变化动态。

Abstract: About 913 soil samples including main great and subgroups have been collected from 117counties and cities of Henan province. For each sample, the total amount of dissolved rareearth element is determined, and the total amount of oxidized rare earth element is given for300 samples, and the analysis of singlet rare earth element is made on some typical sections.The background content, the relation between distribution rule and enpironment of rare earthelements ard revealed, and their movement, accumulation and change trend in the geochemicalprocess in Henan soils are outlined as well.
