摘要
从2010～2012年对曲阜市吴村镇峪口东村棕壤试验地3种土地利用类型下土壤有机碳进行研究,结果表明,表层土壤有机碳含量及碳密度高低为耕地＞休耕地＞荒地,耕作方式是耕地表层有机碳含量及有机碳密度较高的主要原因.试验区表层土壤有机碳密度在国内处于一般水平状态,在时间上试验区耕土壤有机碳呈长期稳定状态,休耕初始阶段则使土壤有机碳含量降低,荒地有机碳呈不规则波动状态.试验区土壤有机碳与人类活动影响下As等理化指标较强显著相关.
The organic carbon of brown soil under three land use types was studied in Yukou Village from 2010 to 2012.The results show that the surface soil organic carbon content and carbon density is：arable land ＞ fallow ＞ wasteland.Farming way is the main reason for the high content and organic carbon density in arable land.Compared with other domestic research,surface soil organic carbon density in the test area is at the general level status,and soil organic carbon in long-term stable state in the test zone.The initial stages of the fallow soil organic carbon content decreased,wasteland organic carbon fluctuated irregularly.Soil organic carbon is significantly associated with these indicators such as As which is under the impact of human activities.
