摘要
通过对比晋西黄土区蔡家川流域人工刺槐林地、人工油松林地、退耕荒草地和农地土壤有机碳和总氮含量的差异性,探讨土地利用变化对该流域土壤碳氮储量的影响。结果表明:(1)4种土地利用类型下,土壤有机碳和总氮均表现出表聚效应,且荒草地降幅最大,各样地土壤有机碳和总氮均呈极显著线性相关。(2)油松林地表层(0-48cm)有机碳含量高于其他样地,刺槐林地表层总氮含量显著高于其他样地,而4种土地利用类型在浅层(48-96cm)和深层(96-160cm)中有机碳和总氮含量差异不显著。(3)从蔡家川流域退耕土壤固碳和固氮效应整体而言,退耕林地具有显著的土壤碳氮固存效应,随着人工林地面积占比的增加,流域土壤总有机碳和总氮储量相应增加。
Through analyze the difference of organic carbon and total nitrogen content in soil profiles under cropland,wasteland,Robiniapseudoacacia forest land and Pinustabulaeformis forest land,to explore the effects of different land use types on the storage of SOC and TN.The results showed as following:(1) Under 4 kinds of land usetypes,we finnd that soil sequestration mainly occurred in the surface soil,as the increase of soil depth,waste land has the biggest decrease of SOC and TN contents,every land use type has the highly significant correlation between SOC and TN contents.(2) In the surface soil layer(0- 48cm),the SOC content of Pinustabulaeformis forest land is significant higher than others,and the TN content of Robiniapseudoacacia forest land is significant higher than others.There are not significant difference among them in superficial layer(48-96cm) and deep layer(96- 160cm).(3) The results also show that at the regional scale,wasteland,Robiniapseudoacacia forest land and Pinustabulaeformis forest land have remarkable SOC and TN sequestration compared with cropland,and the artificial forest land is the best.The increase of forestland area will enhance the storage of SOC and TN in this watershed.
