| 摘 要： | 土壤颗粒组成决定着土壤的物理、化学和生物特性.不同的土壤机械组成,在矿物组成上有显著的差别,其化学成分和其它各种性质也均不相同.土壤机械组成对土壤中元素含量的影响,国内外曾有报道.但两者间相关性的研究报道不多.Ure曾研究过苏格兰10种土壤中61种元素之间的相关系数,讨论了元素与母质的关系.

| Abstract: | The contents of Cd,Hg,As,Cu,Zn,Pb,Co,Mn,Ni,Cr,Li,Fe,Ti,Ca,Sr and Zr in 91 samples of soils developed on alluvial deposits in Tianjin region were determined by Xray fluorescence and colorimetry and their mechanical compositions were determined by gravimetry.The correlation between the rnntents of those elements and machanical compositions of the soils were studied,and the data obtained indicate that the soil particles with 0.01 mm diameter is a obvious critical limit. |
