Abstract:

秦岭山系是我国南北气候的分界线,地理位置独特,对气候变化响应比较明显,气温升高会影响其土壤碳释放。因此对秦岭土壤CO2释放特征的研究具有重要意义。通过对秦岭主峰太白山六种不同植类型土壤CO2释放特征的野外测定,结果表明,太白山土壤CO2的释放从8:00-11:00升高,11:00-16:00达到峰值;土壤CO2的释放速率的大小顺序是:阔叶栎林>桦木林>落叶阔叶林>太白红杉林>秦岭冷杉林>高山草甸。不同植被类型土壤CO2的释放速率与温度呈正相关,与地表气温以及土层深度0~5cm处温度呈极显著正相关性。不同植被类型土壤CO2释放速率的Q10顺序是:秦岭冷杉林>桦木林>阔叶栎林>高山草甸>落叶阔叶林>太白红杉林。
