| 中文摘要: |
| 测定了4 个季节的大型垂直潜流人工湿地中基质有机碳含量，以研究植物组成与多样性，包括植物物
种多样性，功能群多样性与植物组成对有机碳季节动态的影响方差分析结果表明院在大型人工湿地中，春季，冬季
植物物种多样性对基质有机碳含量有显著正效应且植物组成四季都有极显著的影响，而功能群多样性四季中都没
有显著效应，因而，当衡量植物多样性对基质营养季节动态如有机碳”的影响时，一般是植物组成和物种多样性要
比功能群多样性更具有说服力，同时，基质有机碳含量在春季，冬季较高而在夏秋季较低，表明基质营养(如有机
碳)的季节动态变化趋势与植物的生长周期相一致，另外四季中基质有机碳含量与基质容重呈显著正相关，而在
2008 年10 月植物生物量与基质有机碳含量呈显著负相关。 |
| 英文摘要: |
| This study attempted to measure the contents of substrate organic carbon(SOC) in four different seasons in a
full-scale constructed wetland in southeastern China to investigate the effects of plant diversity (i.e., plant species diversity,
functional group diversity and plant composition) on seasonal dynamics of SOC. ANOVA analysis in this study showed that
plant species diversity had significant effect on SOC in Spring (April, 2008) and Winter (January, 2009), and plant
composition had very significant effect, while functional group diversity had no significant effect in the four seasons.
Therefore, plant species diversity and composition in general explained much more about the measured nutrient cycling
processes (such as SOC) than did functional group diversity in high nutrient supply in the full-scale constructed wetland.
Meanwhile, all treatments had the highest SOC pool size in Winter and Spring. While those in Summer (July, 2008) and
Autumn (October, 2008) were lower, indicating that the seasonal dynamic rules of SOC were very consistent with plant
growth cycle. In addition, in four seasons, soil organic carbon content decreased with the increase of soil bulk density, and
plant biomass decreased with the increase of SOC in October, 2008. |
