腐殖质化 meaning in Chinese
humification
Examples
- The final process in organic matter decomposition is known as humification .
有机物分解的最后程序称为腐殖质化。 - 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
实验结果表明：粘粒粉沙比值能很好地指示粉尘堆积物的次生粘化作用；磁化率和全铁很好地指示生物风化成壤作用； sr和rb sr比值能很好的指示生物风化成壤作用和淋溶作用；总有机碳( toc )含量的高低，在一定程度上反应了土壤发育过程中气候和植被状况的变化，指示着成壤过程中腐殖质化的程度； caco3含量的变化，可以反映了黄土古土壤形成时的风化成壤作用的强弱程度，指示成壤过程中的淋溶作用和次生碳酸盐化作用；并且各指标所指示的成壤环境和成壤强度存在明显的区域差异，即渭河流域土壤的生物风化成壤作用、次生粘化作用和淋溶作用均表现出南部强于北部。
