以典型区域茅尾海红树林自然保护区为样区,采样估算广西红树林湿地沉积层有机碳储量.结果表明,红树林土壤有机碳含量平均值从大到小排列顺序为混交林＞桐花＞光滩,0～50 cm土层分别为2.797％、1.218％和0.870％;红树林湿地土壤有机碳储量由大到小依次为混交林＞桐花＞光滩,混交林、桐花和光滩0 ～ 50 cm土层土壤有机碳储量分别为142.79、47.25和47.21 t/hm2.与周边红树林地区相比,钦州湾混交林的各层土壤碳储量与深圳湾红树林和海口的白骨壤接近,但远低于深圳福田的秋茄林和海口的桐花,而钦州湾桐花、光滩的各层土壤碳储量与深圳湾光滩较接近.
An Estimation of Soil Organic Carbon Storage in Mangrove Wetlands of Guangxi
Taking Mao Wei Sea mangrove nature reserve as a typical sample area,organic carbon storage of mangrove wetland sediment was estimated according to sample analysis.The results showed that:the order of soil organic carbon storage was mixed species ＞ Aegiceras corniculatum ＞ bare flat,the average content organic carbon in the mangorove wetland soil (0-50 cm depth) were 2.797％,1.218％ and 0.870％ respectively;The order of soil organic carbon storage per unit area is mixed species ＞ Aegiceras corniculatum ＞ bare flat,carbon storage in the mangrove wetland soil (0-50 cm depth)were 142.79,47.25 and 47.21 t/hm2 respectively.Contrast with the mangrove wetland surrounding area,soil carbon storage of mixed species in Qinzhou Bay close to that of Vicennia mariana in Shenzhen Bay and Haikou,but much lower than that of Kandelia candel in Shenzhen Futian and Aegiceras corniculatum in Haikou.The soil carbon storage of Aegiceras corniculatum and bare flat in Qinzhou Bay is closer to that of bare flat in Shenzhen Bay.
