应用WCL-1型磁化率仪对省内几种主要土壤进行磁测.结果表明,153个耕层土壤磁化率范围值为4～120K·10~(-6)emu/cm~3.按土类分,暗棕壤>黑土、栗钙土>台地白浆土、黑钙土>草甸土、碱土.影响土壤磁化率的主要因素是:(1)磁化率与有机质含量成正相关;(2)发育在火山喷发物上的暗棕壤磁化率>发育在花岗岩坡积物上的暗棕壤,黄土母质黑土>红土母质黑土的磁化率;(3)还原条件下的土壤磁化率降低.土壤磁测可能对土壤分类和定量土壤成分等方面有一定的意义.
The magnetic susceptibility of several main soils in the province was measured by WCL-1 magnetic susceptibility meter.The results showed that the soil susceptibility range of 153 tillage layers was 4 ~ 120K · 10 ~ (-6) emu / cm ~ The main factors influencing the soil magnetic susceptibility are: (1) there is a positive correlation between magnetic susceptibility and organic matter content; (2) ) Magnetic susceptibility of dark brown soil developed on volcanic eruptions> Magnetic susceptibility of dark brown soil, loess parent black soil> red soil parent black soil developed on granite slope sediments; (3) Soil magnetic susceptibility decreased under reducing conditions. Soil Magnetometry may have some significance in soil classification and quantitative soil composition.
