| 摘 要： | 陆地生态系统土壤有机质(SOM)的碳动态研究已引起科学界的广泛关注,对海陆交错带的相关研究则较少。本研究选取位于广东湛江红树林保护区高桥三个天然红树林群落土壤剖面,采用C同位素方法测定了土壤有机碳(SOC)含量。结果表明,地表100cm土壤碳库分别为:桐花树(Aegiceras corniculatum)群落碳库量较大,达673.2Mg/ha,而木榄(Bruguiera gymnorrhiza)+秋茄(Kandelia candel)群落为371.9Mg/ha,白骨壤(Avicennia marina)群落为325.2Mg/ha。有机质分解过程、植物根系分泌物和凋落物的差异、潮汐作用、群落演替阶段以及生物干扰等,都会对红树林土壤的碳动态产生一定的影响。

| Abstract: | Steadily increasing concentrations of atmospheric CO2 have drawn considerable worldwide attention to the carbon dynamics of soil organic matter(SOM) under different vegetative conditions.We examined the soil profiles of three natural mangrove stands in Zhanjiang,Southern China,comparing their soil organic carbon(SOC) content.In the upper 100cm,the carbon storage values in the Aegiceras corniculatum,Bruguiera gymnorrhiza+ Kandelia candel,and Avicennia marina profiles were 673.2,371.9,and 325.2Mg/ha,respectively.The depositions such as root and litter and other processes,such as tidal influences,successional stages,and bioturbation,also contributed to this kind of pattern. |
