摘要

海洋生态系统是最绿色的海洋生态系统之一,在海洋生物中发挥着重要作用,也是生产力最高的新生态系统之一。目前,由于公众对海洋生态系统的功能缺乏了解,海洋生态系统不太受关注。因此,公众维护生态系统健康的努力微乎其微,有时甚至被认为是干扰植物,因此它们最终被忽视或破坏。研究目的是传播对杜逊第四区、西片洼地、西伦巴第区水域古代群落结构的生态学研究。本研究中使用的方法是一种直接的实地实验,使用有目的的采样技术,使用50x50cm的正方形样带观察古代社区结构,样带的站点数量固定为3(三)个。车站的距离和布局基于红树林、羊肉和珊瑚礁的接近,重复三个珊瑚礁,因此在本研究中有9(九)个transecs平方。至于在那里进行的水质测量。研究表明,有四种类型的羔羊,分别是橡子Enhalus acoroides、铁杉Thalassia hemprichii、圆腹圆腹圆背圆腹圆脊圆腹圆唇圆腹圆尾圆脊圆脊圆唇圆脊圆尾圆唇圆唇圆尾圆腹圆纹圆腹圆颈圆腹圆底圆腹圆翼圆腹圆翅圆腹圆顶圆腹。古群落的结构,如密度、频率及其对杜逊第四区水域的封闭或贡献,以圆形Cymodocea型为主。海草生态系统是浅海生态系统之一,在海洋生物的生活中发挥着重要作用,是生产力最高的海洋生态系统之一。由于公众对海草生态系统的功能缺乏了解,海草生态系统目前受到的关注较少。因此,社区为保护这一生态系统所做的努力微乎其微,有时它们被认为是有害植物,因此最终被忽视或破坏。本研究旨在描述对西龙目摄政区西Sekotong区Ketapang Hamlet水域海草群落结构的生态学研究。本研究中使用的方法是通过使用有目的采样的采样技术在现场进行的直接实验。使用50x50 cm的象限样带和3(三)个观测站对海草群落结构进行观测。站点的距离和布局基于红树林、海草和珊瑚礁栖息地的接近,三个钩子重复,因此在本研究中有9(九)个象限样带。至于在现场进行的水质测量。结果表明,该海域共有4种类型的海草,分别为橡果海鞘(Enhalus acoroides)、海鞘海鞘(Thalassia hemprichii)、圆脊海鞘(Cymodocea rotundata)和卵圆海鞘(Halophila ovalis)。海草群落结构,如密度、频率和覆盖率及其贡献

Struktur Komunitas Lamun di Perairan Ketapang, Lombok Barat
Ekosistem lamun adalah salah satu ekosistem laut dangkal yang mempunyai peranan penting dalam kehidupan biota laut dan merupakan salah satu ekosistem bahari yang paling produktif. Ekosistem lamun saat ini kurang mendapat perhatian dikarenakan kurangnya pengetahuan masyarakat tentang fungsi ekosistem lamun. Akibatnya, upaya masyarakat dalam menjaga kelestarian ekosistem ini sangat minim bahkan terkadang dianggap sebagai tanaman pengganggu, sehingga akhirnya diabaikan atau dimusnahkan. Penelitian in bertujuan menjabarkan kajian ekologi struktur komunitas lamun di perairan Dusun Ketapang, Kecamatan Sekotong Barat, Kabupaten Lombok Barat. Metode yang digunakan dalam penelitian ini adalah percobaan langsung di lapangan dengan mengguanakan teknik pengambilan contoh secara purposive sampling Pengamatan struktur komunitas lamun menggunakan transek kuadran berukuran 50x50 cm dengan jumlah stasiun yang ditetapkan sebanyak 3 (tiga) stasiun. Jarak dan tata letak stasiun berdasarkan pendekatan habitat mangrove, lamun, dan terumbu karang dengan pengulangan sebanyak tiga kail, sehingga dalam penelitian ini terdapat 9 (sembilan) transek kuadran. Adapun terkait pengukuran kualitas air dilakukan secara in situ. Hasil penelitian menunjukkan bahwa terdapat 4 jenis lamun, yaitu Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, dan Halophila ovalis. Struktur komunitas lamun seperti kerapatan, frekuensi, dan penutupan maupun kontribusinya di perairan Dusun Ketapang didominasi oleh jenis Cymodocea rotundata.  The seagrass ecosystem is one of the shallow marine ecosystems that has an important role in the life of marine life and is one of the most productive marine ecosystems.

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.
