本文根据宁夏1000余个土壤样品的磁化率数据和300个土壤磁化率剖面得出的几项磁性诊断指标。即:(1)土壤磁化率的总体平均数(土壤的磁变幅)μkω;(2)表土层的磁化系数fa;(3)特征层的磁化系数fe;(4)全剖面的磁化系数fp。这些指标能反映土壤的形成过程及肥力变化,可作为分类的依据之一。
In this paper, based on the magnetic susceptibility data of more than 1000 soil samples in Ningxia and 300 soil magnetic susceptibility profiles obtained by several magnetic diagnostic indicators. Namely: (1) the overall average of soil susceptibility (soil magnetic amplitude) μkω; (2) the surface soil magnetization coefficient fa; (3) the characteristic layer of the magnetization coefficient fe; (4) the full profile of the magnetization coefficient fp . These indicators can reflect the process of soil formation and fertility changes can be used as a basis for classification.
