2012年对海南省麒麟菜保护区内野生麒麟菜资源进行调查研究。结果表明,海南省麒麟菜自然保护区有琼枝和耳突卡帕藻2种麒麟菜,优势种为琼枝。保护区内麒麟菜分布面积约为19.40 km~2,平均覆盖度为0.54%,平均生物量为7.30 g/m~2。其中文昌海域约为14.35 km~2,平均覆盖度为0.55%,平均生物量为7.85 g/m~2;琼海海域约为5.05 km~2,平均覆盖度为0.49%,平均生物量为5.78 g/m~2。伴生生物有33科50种,其中多毛类有9科14种,软体动物有14科17种,甲壳类9科18种以及棘皮动物1科1种,平均生物量为6.38 g/m~2,平均栖息密度为72.72个/m~2。优势种为斑纹围沙蚕、地中海巨亮钩虾、雷氏藻钩虾和四肢舟钩虾。受草食性动物、渔业活动、陆源污染和海洋工程影响海南省麒麟菜保护区麒麟菜大面积减少。
In 2012, the research on the wild Eucheuma resources in the Eucheuma protected area of Hainan Province was conducted. The results showed that there were 2 kinds of Eucheuma in Qionglai Nature Reserve in Hainan Province and two kinds of Koehnaga in Euglena were the dominant species. Euonymus japonicus in the reserve covers an area of about 19.40 km ~ 2 with an average coverage of 0.54% and an average biomass of 7.30 g / m ~ 2. The Wenchang sea area is about 14.35 km ~ 2, the average coverage is 0.55% and the average biomass is 7.85 g / m ~ 2. The Qionghai area is about 5.05 km ~ 2, the average coverage is 0.49% and the average biomass is 5.78 g / m ~ 2. There are 33 families and 50 species of concomitant organisms, of which there are 14 species of polychaetes, 14 species of 17 species of molluscs, 18 species of 9 families of crustaceans and 1 species of echinoderms. The average biomass is 6.38 g / m 2, The average habitat density was 72.72 / m ~ 2. The dominant species of striped nematodes, Mediterranean shining giant shrimp, Rehmannia hook shrimp and four limbs hook shrimp. Affected by herbivores, fisheries activities, terrestrial pollution and marine engineering, the Eucheuma Minnesota Protected Area in Hainan Province is greatly reduced.
