摘要

O是3大主要温室气体之一

目前对湿地N

O研究主要集中于河口和自然湿地

而城市湿地由于受到人为的强烈干扰和集中管理

其N

O排放特征尚未得到充分认识和研究. 以广州市海珠湖城市湿地为例

通过静态箱−气相色谱法

研究2013年12月~2014年11月期间的美人蕉(

Canna indica

CI)、野芋(

Colocasia tonoimo

CT)、蓝花草(

Aphelandra ruellia

AR)3种典型群落湿地的N

O排放通量季节性变化及相关环境因子. 结果表明: 美人蕉、野芋、蓝花草3种植被群落在无水区N

Abstract

The objectives of this study are to investigate the fluxes of N

O from urban wetlands

and to find the related environmental factors. The enclosed static chamber-gas chromatography method is used to analyze the N2O fluxes of

Canna indica

(CI)

Colocasia tonoimo

(CT) and

Aphelandra ruellia

(AR) from December 2013 to November 2014 in the typical urban wetland of the Haizhu Lake in Guangzhou City. The results shows that the average annual fluxes of N

O in the water-free areas are 0.029 mg·m

for CI

0.089 mg·m

for CI

for CT

0.022 mg·m

for AR in the water areas. Differences in N

O fluxes between different seasons are obvious. Water level and temperature are significant factors affecting N

O emission

while the influence of different plants community type is not significant. The N

O emission flux goes to the largest when the temperature is at 25～35°C.
