摘要(Abstract)：

采用样方对角线混合法采集土壤样品,用圆锥四分法分样,测定土壤有机碳及相关土壤因子理化性质,用单因素方差法比较不同排土场各土壤因子的差异性,用主成分分析法(PCA)分析了土壤有机质与土壤因子、复垦方式、复垦年限间的关系。结果表明:1)影响排土场土壤环境的第1主成分为复垦管理相关因子,贡献率为71.43%,第2主成分为排土工艺相关因子,贡献率为12.10%;2)排土场土壤有机质与土壤水分、土壤孔隙度、复垦方式和复垦年限呈正相关,与土壤容重、土壤黏粒含量和土壤pH值呈负相关;3)相同复垦年限时,油松(Pinus tabulaeformis Carr.)+蒙古冰草(Agropyron mongolicum Keng)组合较新疆杨(Populus alba var.pyramidalis Bunge)+紫花苜蓿(Medicago sativa L.)复垦模式有利于土壤有机碳积累,但复垦14 a土壤有机碳含量最高的排土场尚未达到对照CK样地土壤有机碳水平。人工维系促建林地生态系统土壤环境尚不稳定。
