大多數黃土被認為是一種風成沉積。Wind-deposited sediment called loess occurs in many places.
被稱為黃土的風成沉積物,在許多地區均有。Loess is easy borne by the wind and may be carried long distances before it falls to earth and becomes topsoil.
黃土易被風颳起並帶至遠處方才落下成為表土層。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。Based on the characters of water erosion and rock clasts, the zhangxia loess is possibly a product of aeolian - talus - pluvial process
張夏黃土下部呈現明顯的水流侵蝕痕跡,中間夾有圍巖碎屑,應屬于風成、坡積、洪積成因的黃土狀土。It is thought that the holocene original sediments were the result of the aeolation in the area, but the stream action influence the formation of deuterogenic loess
認為本地區全新世原始沉積物是風成的,但流水作用影響了次生黃土的形成。( 2 ) there is stage of soil formation from the evolution of pedogenic environment in the weihe valley during holocene. soil formation shows the law of evolving from warm and wet strong soil formation period to cold and dry dust deposition period ( weak soil formation period ) and to warm and wet strong soil formation period again. the loess - soil sequence is a compound soil sectional system of different kinds of soil evolution under different bio - environment and pedogenic processes
( 2 )通過對全新世渭河流域成壤環境演變問題的討論,揭示了全新世渭河流域土壤的發育具有階段性,表現為由溫濕的強成壤期向冷乾的沉積期(弱成壤期)演變、再向溫濕的強成壤期演變的規律;黃土一古土壤序列是不同生物氣候環境下、不同成壤過程發育的不同土壤類型演替而形成的復合型土壤剖面體系;而且由於冬夏季風環流及其環境效應在空間上的差異,使得復合型土壤剖面體系也存在著南北差異。The gullies are formed by the processes of infiltration - interflow - collapses. ( 2 ) in the slope with sand - loess, the major factors of water erosion are the rainfall intensity and rainfall amount of annual first rainfall. ( 3 ) in the region, the evolution processes of slope gully system results from alternative actions of sand deposition and water erosion
