对 Si、Al、Fe、Ca、Mg、Mn、K、Na和 P等元素在南极菲尔德斯半岛地区三个代表性土壤剖面 (不饱和寒冻雏形土、纤维质寒冻有机土和鸟成土 )中的迁移与富集规律进行了研究 ,结果表明 ,本区土壤中物质移动和元素迁移现象明显 ;几种主要元素在不同类型土壤以及同一土壤不同层次中的移动行为有显著差异 ,土壤自由水状况和地表生物活动在元素迁移与富集过程中发挥重要作用。另外 ,在土壤发育和土壤粘粒形成过程中 ,不同元素在不同土壤颗粒之间的再分配现象存在较大差异。
Three representative soil profiles of Si, Al, Fe, Ca, Mg, Mn, K, Na and P in the Fildes Peninsula of Antarctica (unsaturated frozen soil, The results showed that there was a significant phenomenon of material movement and element migration in the soil of this area. There were significant differences in the movement behavior of several main elements in different types of soils and in different layers of the same soil. Soil free Water conditions and surface biological activities play an important role in the migration and enrichment of elements. In addition, redistribution of different elements between different soil particles is quite different in soil development and clay formation.
