| 摘 要： | 选择处于全球变化中国东北样带东部典型生态系统的长白山阔叶红松林作为研究区，采用动态气室-CO2红外分析法测定了森林生态系统不同退化阶段的土壤呼吸作用.结果表明：在生长季，长白山阔叶红松林不同退化阶段的土壤呼吸动态变化呈单峰型曲线，在7-8月达到最大值；不同退化阶段林地土壤呼吸大小顺序为：杨桦林＞蒙古栎林＞阔叶红松林＞硬阔叶林＞裸地.其中，杨桦林和蒙古栎林样地的碳释放量分别为对照阔叶红松林的1.4和1.3倍，硬阔叶林和裸地的碳释放量分别为对照阔叶红松林的88%和78%.

| Abstract: | Taking the broad-leaved Korean pine forest area in Changbai Mountains,a typical eastern forest belt of Northeast China for global change as test object,and by using the approaches of trenching-plot and infrared gas exchange analyzer,this paper analyzed the soil respiration in a selected series of degraded Korean pine forest ecosystem,i.e.,broad-leaved Korean pine forest (CK),poplar-birch forest (Y),hardwood forest (S),Mongolian oak forest (M),and bare land (L). In the growth season of the forests,soil respi... |
