- 摘要:
- 对黔中典型喀斯特地区，对不同土地利用方式下的土壤矿物磁性做了研究.研究结果显示，典型喀斯特地区发育的土壤的磁性矿物组成一致，基本上是以亚铁磁性矿物为主，多畴颗粒(MD Multi-Domain，>0.04 μm)、稳定单畴颗粒(SSD Stable Single Domain，0.02～0.04 μm)和超顺磁颗粒(SP Super Paramagnetism，＜0.02 μm)三种颗粒都含有.不同的土地利用方式对土壤的磁性特征有着明显的影响，林地和耕地的磁性矿物中含有较多的细颗粒物质，而撂荒地、草地和灌丛地则相对较少;土壤中细颗粒的磁性物质的含量又与土壤本身的黏粒含量有明显的相关关系;土壤中反铁磁性矿物的含量均较少，其中耕地的反铁磁性物质的含量明显高于其他土壤，可能与长期渍水和耕种翻作有关.
- Abstract:
- Study on magnetic susceptibility,frequency dependent susceptibility,anhysteretic remanent magnetization,acquisition curve of isothermal remanent magnetization,saturation isothermal remanent magnetization and demagnetization parameters on soils of different land uses in Karst mountain area.The result shows that the magnetic mineral is mainly composed of ferrimagnetic with different grain sizes,such as multi-domain,stable single domain and super-paramagnetism.The different land uses of soils will impact the composition of magnetic minerals.The soils in woodland and cultivated land will have more fine grain size than those in grassland,fallow field and shrub land.The content of fine magnetic minerals is also correlated with the clay particle content,and the content of anti-ferrimagnetic minerals in cultivated land are more than other four types,it is maybe related to paddy soil’s farming and perennial waterlogging.
