摘　　要：采用Komiyama红树林异速生长模型，对海南文昌清澜港海莲-黄槿生态系统的植被生物量、碳密度及其空间分布特征进行研究。研究结果表明：海莲-黄槿植被层总生物量为389.57±12.73 t/hm2，其中，乔木层生物量为387.75±12.01 t/hm2，占林分植被层总碳密度的99.5%；海莲-黄槿生态系统总有机碳库密度为688.51±45.69 t/hm2，其中，群落植被层单位面积的碳贮量为184.5 t/hm2，占总碳贮量的26.6%；0～105 cm土壤有机碳单位面积的贮量为504.01±39.69 t/hm2，占生态系统总碳密度的73.2%；林下植被层和现存凋落物层仅占0.2%。Vegetation biomass, carbon density and its spatial distribution characteristics ofBruguiera sexangula andHibiscus tiliaceus mangrove ecosystem in Qinglan Barbor of Wenchang city, Hainan province by using Komiyama mangrove allometric growth model. The results show that the total vegetation layer biomass of the mangrove ecosystem was 389.57± 12.73 t/hm2, and of them the tree layer biomass was 387.75±12.01 t/hm2, accounting for 99.5% of the total carbon density of forest vegetation layer; Total organic carbon density of the mangrove ecosystem was 688.51±45.69 t/hm2, of them the vegetation layer carbon capacity per unit area was 184.5 t·hm-2, accounting for 26.6% of the total carbon reserves; 0～105 cm soil organic carbon of per unit area was 504.01±39.69 t·hm-2, accounting for 73.2% of the total ecosystem carbon density, the soil organic carbon sum in undergrowth layer and existing litters layer accounted for only 0.2%.
