| 中文摘要: |
| 结合2008年和2014年的调查数据,对海南岛南部海草分布现状进行分析探讨。结果显示,海南岛南部海草种类有2科3亚科5属5种,即海神草 Cymodocea rotunda、泰莱藻 Thalassia hemprichii、海菖蒲 Enhalus acoroides、喜盐草 Halophila ovalis 以及二药藻 Enhalus acoroides,泰莱藻广泛分布;海草分布面积从2008年的1.64 km2减少到2014年0.50 km2,减少幅度较大区域为铁炉港和小东海;平均盖度从2008年35.67%下降到2014年26.40%;受人为活动及无人管理因素影响程度不同,海南岛南部不同海域海草平均密度及平均生物量各有不同,后海湾与鹿回头海草平均密度和平均生物量呈增长趋势,铁炉港、西瑁洲岛及小东海海草平均密度和平均生物量呈下降趋势。鉴于海南岛南部海草资源已出现退化,希望社会各界重视海草的保护,在海草资源丰富区域设海草保护区,在海草破坏严重区域加大政府科研扶持力度,对海草进行保护与修复。 |

| Analysis and discussion of the distribution status of the seagrass in the southern part of Hainan island, based on the investigation data that were collected in 2008 and 2014. The results show that, the species of the seagrass in the southern part of Hainan island have 2 families, 3 subfamily, 5 genera and 5 species, namely Cymodocea rotunda, Thalassia hemprichii, Enhalus acoroides, Halophila ovalis, Enhalus acoroides, and the Thalassia hemprichii was distributed widely. Tielugang lagoon and Xiaodonghai were the decreased greatly areas, when the distribution of the seagrass has decreased by 1.64 km2 to 0.50 km2, and the average coverage of seagrass was downed by 35.67% to 26.40% from 2008 to 2014. It was difference to the average density and average biomass when they was subjected to the different influencing factors of the human activity and no one manage. The average density and biomass have increased in Huohai Bay and Luhuitou, while them have decreased in the areas just as Tielugang lagoon, Ximaozhou Island and Xiaodonghai. It hopes all society sectors to protection of seagrass, set up seagrass reserves in the rich seagrass resources areas, increase the government scientific support to protection and restoration of seagrass in the destroyed severity areas, in view of the seagrass resources has showed a degradation phenomena. |
