摘  要：
以涡度相关系统观测的数据为资料,对矮嵩草草甸2002年的地面热源强度和地面热量平衡以及地上、地下生物量进行了研究。结果表明,在此观测期内,青藏高原矮嵩草草甸的地面均为热源,热源强度具有明显的季节变化,地面热源强度的平均值为88.5 W.m-2;地上、地下生物量也呈现明显的季节变化,地上生物量与热源强度有正相关关系,而地下生物量与热源强度则出现较复杂的关系,在生长季前期和后期表现为一定的正相关关系,在生长季中期则呈现为负相关关系。

摘  要：
Based on the data measured by the eddy covariance method,the intensity of surface heating source and energy balance,and aboveground biomass and underground biomass in an alpine meadow were analyzed in 2002.The results showed that the surface of alpine meadow was heating resource,and the there was an evidently seasonal variation in heating intensity,average of intensity of surface heating source was 88.5 W·m~-2 in 2002.The aboveground and underground biomass also had a seasonal variation,respectively.There was positive correlation between aboveground biomass and heating intensity,while complex relationship between underground biomass and heating intensity existed.In the beginning and end of the growing season,positive correlation occurred,while at the middle of the growing season,negative correlation appeared.
