摘要
2004～2009年对海南岛周遍海域的海草资源进行综合调查,结果表明:海南岛海草资源丰富,共有6属10种,面积约55 km2,优势种为泰莱藻;海南岛海草分布于近岸海域的珊瑚坪内侧或泻湖沿岸,主要位于潮间带低潮区和潮下带上部4m水深范围;海草生物量范围为71.24～727.24 g/m2,平均为410.26 g/m2;海草密度范围为4 131.20～550.40株/m2,平均为1 753.39株/m2。海南岛海草主要受陆源污染、海洋工程、渔业活动、非法渔业等活动影响。
From 2004 to 2009,a comprehensive survey of sea-grass resources on the surrounding waters of Hainan Island was carried out.The result showed that There were 6 genera and 10 species.The total area was about 55 km^2.The dominant species was Thalassia hemprichii.The sea-grass was distributed in the reef-back or along the lagoon,mainly between the low tide zone and 4 m depth in the sub-tidal areas.The range of sea-grass biomass was 71.24-727.24 g/m^2,which was 410.26 g/m^2 in average.The sea-grass density was between 4 131.20 and 550.40,averaging 1 753.39 d/m^2.The sea-grass was mainly threaten by the land-based pollution,marine engineering,fisheries,illegal fishing and other activities.
