英文: Abstract: Soil incubation experiments were conducted in lab to delineate the effect of soil temperature and soil water content on soil respirations in broad-leaved/Korean pine forest(mountain dark brown forest soil),dark coniferous forest(mountain brown c

中文: 文摘:为了研究土壤温度和土壤含水量对阔叶红松林(山地暗棕壤)、云冷杉暗针叶林(山地棕针叶林土壤)和岳桦林(生草森林土)的土壤呼吸的影响,于2001年9月在长白山进行了土壤实验.利用增加土壤样柱的含水量,将土壤含水量分为9%,、21%、30%、37%和43%5个等级,土壤样品分别在0、5、15、25和35℃的温度下保持24小时.阔叶红松林土壤在0(35℃范围内,土壤呼吸速率与温度呈正相关.在一定的含水量范围内(21%(37%),土壤呼吸随含水量的增加而升高,当含水量超出该范围,土壤呼吸速率则随含水量的变化而       更详细...
