| 摘 要： | 运用静态箱-预浓缩-气相色谱-质谱法和静态箱-色谱法分别测量了南亚热带鼎湖山针阔叶混交林土壤-大气COS和CO2通量。结果表明,土壤吸收COS,凋落物保留样地COS吸收速率显著高于凋落物去除样地,3月土壤COS吸收速率最高。土壤COS吸收速率与大气COS浓度正相关。土壤COS吸收速率与土壤温度、土壤含水量单独未表现出显著相关性,但凋落物保留样地COS吸收速率与土壤温度和含水量两者共同呈二次多项式相关。凋落物保留样地CO2释放速率高于凋落物去除样地。与土壤COS吸收速率相反,土壤CO2释放速率3月最低,7月最高,主要受温度和土壤含水量的影响。土壤CO2释放速率与土壤温度呈指数相关,与土壤含水量直线相关,多元回归分析表明,土壤CO2释放受温度和含水量的共同影响。土壤COS吸收速率随土壤CO2释放速率的增加而增加,表明两者可能受某些共同因素的影响。 |

| Abstract: | Static chamber-preconcentrator-GC-MS and static chamber-GC techniques were applied respectively to measure COS and CO2 flux between soil and atmosphere in a coniferous and broad-leaved mixed forest in Dinghushan Biosphere Reserve in Guangdong province,low-subtropics China.The results showed that soil acted as sink for COS,and COS uptake rates at plots with litter were significantly higher than those without litter.The highest rates were found in March.COS uptake rates were influenced mainly by ambient COS c... |
