| 摘 要： | 报道了浙江建德青冈林碳素的含量、现存量、存留量、归还量、释放量以及在生态系统中的动态过程。结果表明：植物群落中碳素含量的变化幅度不大，一般在１０％以下。其中，叶片（器官比较）、乔木层（层次比较）和春夏季（季节比较）的含量稍高，根系、草本层、秋冬季的含量稍低。群落的碳素现存量为６６．１１３ｔ／ｈｍ２，主要集中在乔木层或常绿树种内；群落的碳素存留量为５．６９１ｔ／ｍ２·ａ；每年通过凋落物归还至地表的量为２．２９６ｔ／ｍ２·ａ；死地被物中又有０．９１１ｔ／ｈｍ２·ａ的碳素释放至大气库中。

| Abstract: | The forest dominated by Cyclobalanopsis glauca is a main subtropical evergreen broad-leaved forest type in South-East China.Carbon dynamics including the concentration,standing crop,retention,return amount via litterfall and release amount is studied.The results show that:The concentration of carbon is higher in spring and summer,leaf and the tree layer,and lower in fall and winter, root and the herb layer.The standing crop of carbon is 66.11t/hm2, and it focuses on the tree layer or evergreen species.The r... |
