Carbon Storage and its influencing factors in Hainan Dongzhangang Mangrove Wetlands of China

The powerful carbon storage function of mangrove has been paid a lot of attention; however, most of the studies were focused on the ecosystem level, or broader scale, while ignored the differences among various communities. This study took Hainan Dongzhaigang mangroves, which has the most complete ecological structure and the richest mangrove species in China, as the research area. Remote sensing and field survey were combined to get the community classification map, then, based on the sampling and testing, the carbon storage in soil, plant and litters of each community was calculated and analyzed. The results showed the total area of Hainan Dongzhaigang mangrove forest was 1576.24hm2 and carbon storage was 16.81×104 t C, among which, 13.45×104 tC(80.03%) was fixed by soil, 2.66×104 tC(15.88%) by plants, and 0.69×104 tC(5.1%) by litters. The comparison between different communities showed that the carbon storage function of Bruguiera marina, Sonneratia caseolaris and Ceriops tagal communities were top in 12 mangrove communities. Further analysis displayed that carbon storage correlated significantly with carbon storage in soil and plant, height, DBH and average interval of the community. Meanwhile, tide locations of mangroves had obvious influences on soil carbon storage; while carbon storage in plant and litters showed significant correlation with community structure too.
