三亚市红树林碳储量与固碳能力分析

Analysis of the carbon storage and fixation of mangrove forests in Sanya

本研究以近10年红树林研究的数据为基础,结合实地考察与调研,探讨了三亚市红树林碳储量与固碳能力.分析发现,三亚地区现存红树林植物和半红树植物共计20科29属31种,现存红树林总面积为54.0～109.6hm2,生物量总量在6.8～13.9×103t范围内,碳储量为3.0～6.2×103t,净初级生产量为1.6～3.2×103t/a,总固碳能力为0.71～1.44×103t/a.三亚地区红树林群落的有效光能利用率为1.9%,属于高固碳能力和高光能利用率的热带生态系统,固碳潜力巨大且具有较强的提升空间.

The carbon storage and fixation of mangrove were analyzed in Sanya based on the data studied on mangrove recent ten years, combined with field investigation. The results indicated that a total of 31 species of mangrove plants belonging to 29 genera in 20 families found in Sanya, and the total distribution area was about 54. 0 ~ 109.6 hm2, the total biomass was about 6.8 - 13.9 ×10^3 t, the total carbon storage was about 3.0 -6. 2 ×10^3 t, the total primary productivity was about 1.6 - 3.2 ×10^3 t/a, and the total carbon fixation was about 0. 71 - 1.44×10^3t/a. The effective solar efficiency of mangrove plant community was 1.9%, which indicated that the ecosystem having high carbon fixation capacity and solar efficiency, and also large carbon storage potential.
