摘要

2004年5月至2005年4月在长江口崇明东滩湿地采用原位静态箱法对甲烷(CH4)排放通量进行了现场测定。结果表明,崇明东滩潮间带(CM)是大气CH4的排放源,且CH4排放具有明显的季节变化规律,中潮滩(CM-2)7月CH4排放最多,其通量为9.27 mg/(m2·h),在次年4月排放最少,只有0.03 mg/(m2·h)。低潮滩(CM-3)在春季5月CH4排放最多,通量为0.09 mg/(m2·h);冬季2月CH4通量值最低,只有0.002 mg/(m2·h),中、低潮滩CH4年平均排放通量分别为2.06 mg/(m2·h)和0.04 mg/(m2·h)。

Abstract

CH4 emission flux was measured in Chongming east intertidal flat(CM) of the Yangtze River estuary by static closed chamber technique from May 2004 to April 2005.The results show that CM is the source of atmosphere CH4;and its emission had significant seasonal variation.Emission flux was highest in July from middle flat(CM-2),its flux was 9.27 mg/(m2穐),while the lowest CH4 flux was 0.03 mg/(m2穐) in April In low flat(CM-3) CH4 emission was maximum in May and its flux was 0.09 mg/(m2穐),while the minimum flux was 0.002 mg/(m2穐) in February.The annual average CH4 emission flux of was 2.06mg/(m2穐) from CM-2 and 0.04 mg/(m2穐) from CM-3 respectively.CH4 emission flux from CM-2 was higher than that from CM-3 obviously,and vegetation,temperature and contents of sediment organic carbon(OC) are major factors which control the CH4 emission.There were significant positive relationships between CH4 flux and temperature and illumination.The photosynthesis of the tidal flat plant,Scirpus mariqueter,increased the CH4 emission in CM-2,but the photosynthesis of bethonic alga and respiration of Scirpus mariqueter restrained the CH4 emission.

Key words： Chongming east intertidal flat; CH4 emission; seasonal variation
