为了探索凋落物量及其N,P化学计量随着季节变化所呈现的规律性和相关关系,以湖南枫香（Liquidamba formosana Hance）人工林两年的凋落物为研究对象,开展凋落物量、各组分产量及其N,P质量分数和质量比生态化学计量特征的研究.结果表明：2012和2013年凋落物总量无显著差异性,分别为5 085.9±657.6 kg·hm^-2和4 935.7±609.7 kg·hm^-2.各组分凋落量从大到小排序为：叶、枝、花果、碎屑.叶的N,P质量分数之间,叶的w（P）与m（N）∶m（P）之间,枝的w（P）与m（N）∶m（P）之间以及碎屑的w（P）与m（N）∶m（P）之间均存在一定的相关性（P〈0.01）.枫香人工林凋落物及各组分产量及N,P质量分数和生态...

In order to explore the regularity and correlation of litter production and its N and P ecological stoichiometry with seasonal changes,we took the object of Liquidamba formosana Hance plantation in Hunan as an example to investigate the production of litter and its components,and ecological stoichiometry characteristics of nitrogen（ N）,phosphorus（ P） and the N and P ratio in each component. The results showed that there was no significant defference of litter biomass in the year of 2012 and 2013,which were found to be 5 085. 9 ± 657. 6 kg·...
