鐵質淋溶土
英文
ferric luvisols-
The main results are following : ( 1 ) the variation of clay / silt ratio can indicate the secondary clay action of dust depositions ; the variations of magnetic susceptibility and total fe content are inferred to be records of the changeable intensity of bio - pedogenesis ; the variations of sr content and rb / sr ratio can indicate bio - pedogenesis, dissolving and leaching action ; the content of total organic carbon ( toc ) can reflect variation of climate and vegetation during soil formation, it indicates the intensity of weathering and bio - pedogenesis ; the content variation of caco3 can show the intensity of dissolving - leaching action and secondary deposit, which was noted as pseudomycilia in pores and fissures in the sediment, so it can indicate the intensity bio - pedogenesis quite well. these proxy indexes also reflect obvious regional difference of pedogenic environment and the intensity bio - pedogenesis ; namely, secondary clay action, dissolving - leaching action and bio - pedogenesis are all much stronger in south than that in north
實驗結果表明:粘粒粉沙比值能很好地指示粉塵堆積物的次生粘化作用;磁化率和全鐵很好地指示生物風化成壤作用; sr和rb sr比值能很好的指示生物風化成壤作用和淋溶作用;總有機碳( toc )含量的高低,在一定程度上反應了土壤發育過程中氣候和植被狀況的變化,指示著成壤過程中腐殖質化的程度; caco3含量的變化,可以反映了黃土古土壤形成時的風化成壤作用的強弱程度,指示成壤過程中的淋溶作用和次生碳酸鹽化作用;並且各指標所指示的成壤環境和成壤強度存在明顯的區域差異,即渭河流域土壤的生物風化成壤作用、次生粘化作用和淋溶作用均表現出南部強于北部。3. the soils are divided into 2 order, 3 suborder, 6 groups in soil taxonomy ; the soil vertical zone strcture of south slope taibai mountain is : ferric - udic argosols ( < 1600m ) - acidi + ferric - udic cambosols ( l 600 - 2700 m ) - bori - udic cambosols ( 2700 - 3400 m ) - molli - gelic cambosols ( 3400 - 3500m ) - umbri - gelic cambosols ( > 3500m )
供試土壤在系統分類中劃分為2個土綱, 3個亞綱, 6個土類;太白山南坡土壤垂直帶譜結構為:鐵質濕潤淋溶土( 1600m )酸性+鐵質濕潤雛形土( 1600 2700m )冷涼濕潤雛形土( 2700 3400m )暗沃寒凍雛形土( 3400 3500m )暗瘠寒凍雛形土( 3500m ) 。
