Community Characteristics and Organic Carbon Storage of Sonneratia apetala-Kandelia obovata Mangrove in Fenglin Bay,Xiamen
摘要
Abstract
The study selected 20-year-old artificial planted Sonneratia apetala-Kandelia obovata in Fenglin Bay,Xiamen as the ob-ject and researched the community structure characteristics and organic carbon storage.The average tree densities of Sonneratia ap-et ala and Kandelia obovata were 1911 and 14178 ind·hm-2;breast diameter were 13.03 and 3.98 cm;height were 7.77 and 3.80 m respectively.Although the density of Sonneratia apetala was significantly lower than Kandelia obovata,its height was significantly higher.Thus,Sonneratia apetala was dominant species.Its canopy density to Kandelia obovata was 79.26% and the community formed a clear two-layer structure.Both Sonneratia apetala and Kandelia obovata came along splendidly with rare dead trees in Son-neratia apetala-Kandelia obovata mangrove in Fenglin Bay,Xiamen.The growth of Sonneratia apetala was similar to that of monotyp-ic Sonneratia apetala in other regions in Xiamen.Compared with monotypic Kandelia obovata in other regions in Xiamen,the breast diameter of Kandelia obovata in Fenglin Bay was lower while its height was higher.Ecosystem total organic carbon storage was 157.63 t C·hm-2,where vegetation and soil(0-50 cm)organic carbon storage were 71.00 t C·hm-2(the carbon storage of Son-neratia apetala and Kandelia obovata were 45.79 and 25.51 t C·hm-2 respectively)and 86.63 t C·hm-2 respectively.Compared with monotypic Kandelia obovata in Xiamen,vegetation organic carbon storage of Kandelia obovata in Fenglin Bay was lower;even though considering the contribution of Sonneratia apetala,vegetation organic carbon storage was still lower than monotypic Kandelia obovata.However,the mix of planting Sonneratia apetala and Kandelia obovata could significantly increase soil organic carbon stor-age,which may increase ecosystem organic carbon storage.These results indicate that the mix planting of Sonneratia apetala and Kandelia obovata is beneficial to the stability and the enhancement of carbon sequestration function of community structure.关键词
