Abstract

Perairan Kepulauan Riau yang terdiri dari pulau-pulau kecil umumnya memiliki ekosistem pesisir yang tersusun dari ekosistem mangrove, ekosistem lamun dan ekosistem terumbu karang. Ekosistem lamun merupakan bagian dari ekosistem pesisir yang memiliki peran tidak kalah penting seperti habitat biota, area pengasuhan, regulasi karbon dan lain sebagainya. Monitoring terkait kondisi ekosistem lamun penting untuk dilakukan dalam rangka mengetahui status ekosistem sehingga kedepan dapat menentukan langkah pengelolaan ekosistem yang baik. Penelitian ini dilakukan pada tahun 2021 di Perairan Kepulauan Riau meliputi Perairan Kota Batam, Perairan Pulau Bintan, Perairan Lingga, Perairan Natuna dan Perairan Anambas. Metode pengamatan dilakukan dengan menggunakan transek garis yang dibantu dengan transek kuadrat dalam mengamati tutupan lamun di setiap lokasi penelitian.  Berdasarkan hasil penelitian yang telah dilakukan ditemukan 11 jenis lamun di Perairan Kepulauan Riau, meliputi spesies Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, Cymodocea serrulata, Halophila ovalis, Halophila minor, Halophila spinulosa, Thalassodendron ciliatum, Halodule uninervis, Halodule pnifolia dan Syringodium isoetifolium. Nilai tutupan berada pada kisaran 20,68%-54,44%, Berdasarkan tutupannya secara umum ekosistem lamun di Perairan Kepulauan Riau berada dalam status sedang.The waters of the Riau Archipelago which consist of small islands generally have coastal ecosystems consisting of mangrove ecosystems, seagrass ecosystems and coral reef ecosystems. Seagrass ecosystems are part of coastal ecosystems that have no less important roles such as biota habitat, nurturing areas, carbon regulation and so on. Monitoring related to the condition of seagrass ecosystems is important to do in order to determine the status of the ecosystem so that in the future it can determine steps for good ecosystem management. This research was conducted in 2021 in the waters of the Riau Archipelago including Batam City Waters, Bintan Island Waters, Lingga Waters, Natuna Waters and Anambas Waters. The observation method was carried out using line transects assisted by quadratic transects in observing seagrass cover at each research location. Based on the results of the research conducted, 11 species of seagrass were found in the waters of the Riau Archipelago, including species of Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, Cymodocea serrulata, Halophila ovalis, Halophila minor, Halophila spinulosa, Thalassodendron ciliatum, Halodule uninervis, Halodule pinifolia and Syringodium isoetifolium. The cover value is in the range of 20.68%-54.45%, based on seagrass cover in general the seagrass ecosystem in the Riau Islands waters is in a poor status.

卵泡海葵在廖群岛水域的种类和状况
廖内由小岛组成的廖内群岛水域通常有由红树林、海葵和珊瑚礁生态系统组成的沿海生态系统。海葵生态系统是沿海生态系统的一部分,在生态系统中扮演着同样重要的角色,如生物生境、养育区、碳调节等。对海草生态系统状况的监测对于评估其生态系统状况至关重要,以便在确定健全生态系统管理的下一步上采取行动。这项研究于2021年在廖内群岛水域进行,包括巴淡岛水域、宾坦岛水域、林加水域、纳拿纳水域和南巴斯水域。观测方法是使用经四边形帮助的横线,在每个研究地点观察海葵。根据所做的研究,在廖内群岛水域发现了11种海草,地中海贫血,cymodochii, cymodochii rotunchii, Cymodocea ovalis, Halophila ovalis, Halophila ovalis, Halophila ovalis,根据其覆盖面积一般为廖内海海葵的一般生态系统,封面的值为2068% - 54.44%。利奥群岛认为较小的岛屿的水域通常有红树林生态系统、海草系统和珊瑚系统的考虑。海洋生态系统是生态系统的一部分,它没有比生物栖息地、苗圃、碳法规和so更不重要的结构。监测ecosystems的关系至关重要,在命令中确定生态系统的状态,这样在未来,它就可以确定采取有利于生态系统的措施。这项研究是在2021年由里奥群岛水域包括巴坦市水域、宾坦岛水域、林加水域、纳纳水域和南巴斯水域的水域进行研究的。每个研究地点的观察结果都采用了四分段关系的观察结果。根据研究受委托的结果,11种西草的物种在我们国家的河流中被发现,包括鼠尾草属、地中海贫血的物种、地中海贫血、cymodochii、cymodochii、cymodochii、cylophila ovalis、Halophila ovalis、Halophila ovalis、封面价值在20% 68%-54.45%的范围内,基于廖内沿海生态系统的覆盖。

期刊介绍: The Journal of Marine Research publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. In the area of biology, studies involving coupling between ecological and physical processes are preferred over those that report systematics. Authors benefit from thorough reviews of their manuscripts, where an attempt is made to maximize clarity. The time between submission and publication is kept to a minimum; there is no page charge.
