| 摘 要： | 研究了１１种固氮和非固氮树种凋落物分解及可利用态Ｎ的释放．结果表明，固氮树木凋落物中Ｎ的生物分解系数、落叶分解过程中干重的损失率及有效态氮的释放分别比非固氮树种高出１．３、１．５和８．２倍．

| Abstract: | tudies on the leaf
litter decomposition and its N release of 11 N fixing and non N fixing tree species showed that
the biological decay coefficient of leaf litter, the dry weight loss of leaf litter during its decay, and
the N release from the leaf litter of N fixing tree species were 1.3, 1.5 and 8.2 times higher than
those of non N fixing ones, respectively. |

| Keywords: | Nitrogen fixing tree species Leaf litter decomposition N release |
