| 摘 要： | 为探讨小飞蓬入侵对伊犁河谷草原生态系统的影响,揭示小飞蓬的入侵机制,对不同入侵程度(轻度、中度、重度)小飞蓬及本地植物猪毛蒿根际土壤有机碳(SOC)、土壤容重和土壤含水量的变化规律进行研究。结果表明:随着小飞蓬入侵程度的加深,土壤SOC含量上升:小飞蓬重度、中度、轻度入侵和猪毛蒿群落土壤有机碳含量平均值分别为16.70、11.31、9.56 g·kg-1和8.23 g·kg-1,表明小飞蓬入侵增加了伊犁河谷草原土壤SOC的含量,随着入侵程度的加深,土壤SOC含量提高更加明显,同时增加了伊犁河谷草原土壤的碳汇功能。从垂直分布剖面上看,4个群落土壤SOC含量变化一致:随着土壤深度的增加而SOC含量减少,且最大土壤SOC含量均出现在0～20 cm土层,小飞蓬重度、中度、轻度入侵和猪毛蒿群落最大土壤SOC含量分别为:20.3、15.0、13.2 g·kg-1和11.5 g·kg-1。小飞蓬重度、中度、轻度入侵和猪毛蒿群落土壤容重平均值分别为5.02、4.94、4.85 g·kg-1和5...
