| 摘 要： | 为研究台风过程对广西红树林净生态系统碳交换的影响,利用北海红树林生态观测试验站涡度相关系统观测的红树林碳通量和气象观测数据,分析台风“韦帕”登陆前后红树林净生态系统碳交换变化特征及其与气象因子的响应关系。结果表明:(1)红树林净生态系统碳交换碳汇峰值在台风登陆前递增并达到极值,台风登陆时碳汇峰值迅速降低,而在台风登陆后期逐渐恢复;(2)饱和水汽压差是小时尺度上红树林净生态系统碳交换的主要影响因子,最大风速和降雨量是日尺度上红树林净生态系统碳交换的限制因子。

| Abstract: | In order to study the effect of typhoon process on carbon exchange of mangrove net ecosystem in Guangxi,the paper analyzed the variation characteristics of carbon exchange of mangrove net ecosystem before and after Typhoon Wipha landing and its response to meteorological factors.The carbon flux and meteorological data of mangrove net ecosystem in Beihai mangrove ecological observation station were used.The results showed that(1)the peak value of carbon sink increased and reached the extreme value before typhoon landfall,and decreased rapidly when typhoon was landing,but gradually picked up in the later stage of typhoon landfall.(2)Saturated water vapor pressure was the main influencing factor of mangrove net ecosystem carbon exchange on the hourly scale,and the maximum wind speed and precipitation were the limiting factors on the daily scale. |
