Distribution of Soil Labile Carbon Along the Northeast China Transect (NECT) and Its Response to Climatic Change

中国东北样带土壤活性有机碳的分布及其对气候变化的响应


基于中国东北样带2001年考察采集土样的实测数据及CO2浓度升高和干旱胁迫的模拟试验资料,分析了土壤活性有机碳的分布特征及其对气候变化的响应。结果表明,样带土壤活性有机碳与土壤有机碳之间呈极显著正相关关系(相关系数R=0.993,p<0.001)。表层土壤活性有机碳平均为(3.5

Terrestrial transects have become an important and effective method for the study of global change. The Northeast China Transect (NECT) is one of the fifteen global transects recognized by IGBP, which is assigned along the latitude 43°30′ N in the mid-l
