为探讨森林生态系统中苔藓枯落物的生态属性与其下层土壤水热之间的关系,采用样地调查法及特征描述统计、相关系数等分析法,对祁连山大野口流域49块样地的青海云杉林苔藓枯落物及其土壤水热特征进行分析.结果表明：苔藓枯落物平均厚度(6.0±0.3)cm,平均含水率为(101.9±6.3)%；0~10、10~20、20~40、40~60、60~80 cm 土层深的土壤含水率平均值分别为(66.24±4.22)%、(57.62±3.23)%、(48.44±3.21)%、(42.81±6.48)%、25.89%,各土层温度平均值分别为(7.2±0.26)(5.2±0.27)(2.8±0.29)(2.0±0.61)(1.6±0.95)℃；苔藓枯落物厚度与海拔、坡向、坡度、胸径、树高、冠长、冠幅、郁闭度、土壤各层含水率和温度等因子均极弱相关,甚至认为不相关；苔藓枯落物含水率与海拔为中度正相关(P<0.05),与40~60 cm 深的土壤含水率存在显著正相关,与其温度成中度负相关.
