选择浙西金华地区兰溪实验观测站六种不同退化程度的红壤为研究对象 ,分析了反映红壤退化程度的物理、化学和生物指标及红壤磁测参数与它们之间的内在联系。结果表明 ,磁性参数与反映红壤退化程度的理化及生物指标均有显著或较显著的相关性。退化程度较轻的香樟林和混交林表现了较低的细晶粒磁性矿物含量和较高的反铁磁性矿物含量 ,退化程度较高的杉木林、桔园、草地则相反 ,细晶粒磁性矿物含量较高且亚铁磁性矿物的相对含量上升。磁性参数和土壤理化生物指标之间良好的相关性表明 ,磁性参数可以作为指示红壤退化程度的重要指标。
In this paper, six different degraded red soils were selected as research objects in Lanxi experimental station in western Jinhua, Zhejiang Province. The physical, chemical and biological indexes that reflect the degree of degradation of red soils, and the intrinsic relationship between them were also analyzed. The results show that there is a significant or significant correlation between the magnetic parameters and the physico-chemical and biological indexes that reflect the degree of degradation of red soil. Cinnamomum camphora and mixed plantations with less degradation show lower fine grain magnetic minerals and higher antiferromagnetic mineral content. Cunninghamia lanceolata, orange orchards and grasslands with higher degrees of degeneration show the lower fine grain The content of magnetic minerals is high and the relative content of ferrimagnetic minerals is increased. The good correlation between the magnetic parameters and the soil biochemical indicators shows that the magnetic parameters can be used as an important indicator of the degree of degradation of red soil.
