But the conflict between them was appeared during our research in field and the discussion with others . it is followed that the former with the rolling bedrock , the mid with mild bedrock and the latter with the stable bedrock relatively . the conflict between two conclusion above arise , what relationship between loess landforms and their bedrock exist 但在野外调查及同其他学者交流中发现两者并非总体对应一致，显示出陕北黄土高原南部黄土塬基底起伏相对较大，北部黄土梁状(为主)丘陵沟壑区及黄土峁状(为主)丘陵沟壑区基底相对平坦的特征。

At the same soil layer , the sic contents on the tops of the hills were higher than those in the gullies , however , the soc contents on the tops of the hills were lower than those in the valleys . the possible factors of influence on the distribution of soil carbon were soil water content and human activities Kriging插值结果显示，在同一土壤层次的不同地貌部位，土壤碳含量存在明显差异，土壤无机碳含量是梁峁地高、沟川地低，土壤有机碳含量是沟川地高、梁峁地低。

On the contrary , the valley soils had the minimum change for the profile sic content and the maximum change for the profile soc content the diversity of the soil profile carbon content change were related to their sources , movements and inversions in the soils 在不同地貌部位的不同层次之间，无机碳含量在地势高的梁峁地的土壤剖面上变化幅度大，有机碳含量在地势低的沟川地的土壤剖面上变化幅度大，二者的差异主要由各自的来源、在土壤中的迁移、转化等的不同所引起。

There is a evolutional phenomenon to have been recognized in shaanbei loess plateau from south to north . that is luochuan district with the loess yuan ( platform land ) in south . yan ' an - an ' sai district with the loess liang ( ridges ) mainly in middle and shunde - mizhi district with the loess mao ( rounded knolls ) mainly in north . this frame and tendency is got and thought to coincide with the styles of their bedrock traditionalh ? called conformability 在长期的研究和调查过程中，发现陕北黄土高原在南北纵向上存在明显的黄土地貌分异现象，即由南向北，大致依次为洛川黄土塬(广义)地貌、延安?安塞黄土梁状(为主)丘陵沟壑地貌、绥德?子洲黄土峁状(为主)沟壑地貌。
