本数据为排露沟流域典型下垫面的10天一次的土壤水分观测资料。采用环刀法取土，烘干法测量土壤水分。土壤剖面分层为苔枯层、0-10cm、10-20cm、20-40cm、40-60cm、60-80cm，部分剖面土壤厚度不够。测量的地表类型包括2600m云杉林、2700m云杉林、2900m云杉、3100m云杉、3300m云杉林、3300m灌丛、3400m灌丛、3500m灌丛、阳坡草地2600m、阳坡草地2700m、阳坡草地2800m、阳坡草地2900m。\n
测量时间为2007年和2008年5月至9月，10日一次测量，根据天气状况选择具体日期开展测量。\n
该数据是排露沟流域水文模拟关键的土壤观测资料。
