| 摘要: |
| 根据2004～2009 年海南岛东海岸长圮港、龙湾、高隆湾、黎安港、新村港等地海草分布区的水质、沉积物、生物质量、栖息地、生物5 个指标调查数据, 按照《近岸海洋生态健康评价指南》(HY/T087-2005)海草生态系统评价方法, 对海南岛东海岸海草床生态系统健康指标进行评价。结果显示, 海南岛东海岸海草床水环境与沉积环境均处于健康状态; 龙湾海草床生物残毒评价为亚健康, 其余站位均处于健康状态; 黎安港与长圮港海草床栖息地评价处于不健康状态, 其余站位均处于健康状态; 黎安港海草床生物评价处于不健康状态, 新村港海草床生物评价处于亚健康状态, 其他地方栖息地与生物评价均处于健康状态。海草床生态系统健康评价显示, 黎安港处于不健康状态, 新村港与长圮港处于亚健康状态, 龙湾与高隆湾处于健康状态。总体上看, 海南岛东海岸分布于珊瑚沿岸海草床生态系统比较健康, 分布泻湖沿岸海草床趁于亚健康向不健康方向转变。本文希望通过对海南岛东海岸海草床生态系统的健康评价研究, 为海草床生态系统的保护与修复提供理论依据。 |

| Abstract: |
| Based on the data of five indexes including water, sediment, biological quality, habitat and biological indicators obtained from the east coast of Hainan Islands including Changpi harbor, Longwan, Gaolong bay, Lian lagoon and Xincun lagoon from 2004 to 2009. The health index to the sea grass bed ecosystem of the east coast of Hainan Islands was assessed according to the inshore marine ecosystem health assessment guide(HY/T087-2005) which was the sea grass ecosystem assessment methods. The results showed that the water and the sediment environment of the sea grass bed ecosystem in the east coast of Hainan Islands were in the state of health. The assessment of the biological toxicity of Longwan showed that was in the state of sub health, and the others were in the state of health. The result of the assessment of the sea grass habitat was that Lian lagoon and Chang pi harbor were in the state of sick. The assessment of the biological Lian lagoon showed that it was in the state of sick. However, the assessment of the others’habitat and biological showed that they were in the state of health. The results of the assessment of the sea grass bed ecosystem health showed that Lian lagoon was in the state of sick, xincun lagoon and changpi harbor were in the state of sub-health, and Longwan and Gaolong Bay were in the state of health. Overall, the sea grass bed ecosystem in the east coast of Hainan Islands located in coral coast was health, while sea grass located in lagoon coast was changed directly from sub-health to unhealthy. This paper provided theoretical foundation to protect and repair the sea grass bed ecosystem for the assessment of health to the sea grass bed ecosystem in the east coast of Hainan Islands. |
