| 摘 要： | 以内蒙古高原短花针茅(Stipa breviflora Griseb.)+冷蒿(Artemisia frigida Willd.)+无芒隐子草(Cleistogenes mutica Keng)的荒漠草原为研究对象,野外自然条件下进行增温设施和施氮肥试验,研究了施肥增温、施肥不增温、不施肥增温、不施肥不增温条件下各土层、各种处理土壤有机质的变化规律.结果表明,在增温、施氮条件下有机质含量均增加,在4种处理条件下土壤有机质含量都随着土层的加深而逐渐降低;增温施氮作用下2008年的有机质含量明显低于2007年.这与当年的雨水有很大关系,对照区不同深度土壤的有机质含量变化规律是一致的,都随着年份的增加而逐渐减少.
