摘要

红树林生态系统可以被一些生物群用作寻找食物的地方、栖息地和庇护所。由于红树林的功能,红树林生态系统的状况可能会下降一级。这将对该地区的渔民、伤亡人员和其他社区的经济产生恶劣影响。需要进行这项研究,以分析帕蒂角塔尤红树林生态系统中存在的红树林群落结构。本研究采用调查方法和有目的的抽样技术来确定其位置。共有4个测站,每个测站由3个地块组成,每个地块10米x 10米用于树级,5米用于儿童。红树林群落结构数据处理是使用微软Excel等软设备完成的。在这项研究中发现了两种类型的红树林:滨海阿维森尼亚红树林和阿尔巴阿维森尼亚红树林。研究地点的红树林列车距离很近。根据其频率值,在每个观测点上总是发现海洋阿维森尼亚型。优势指数的结果表明,在第一阶段至第四阶段,有一些类型占主导地位,其值范围为0.7–0.78。最高的INP可用于阿维森尼亚海洋,其值为260%且较高。多样性指数的结果表明,该研究地点的红树林多样性较低。而等值指数的值包含在当前和较少的类别中。水质参数(温度、pH、盐度、基质和硝酸盐含量、磷酸盐基质)通常被指定为适合红树林生活且有益的参数。[UNK]红树林生态系统可被一些生物群用作觅食、产卵和苗圃。红树林生态系统的状况可能会下降,其中之一是由于红树林的转变。这将对该地区渔民、农民和其他社区的经济产生不利影响。本研究旨在分析Pati Regency Tayu区红树林生态系统中红树林群落的结构。本研究采用了一种调查方法和有目的的抽样技术来确定位置。共有4个站点,每个站点由3个地块组成,每个地块的树木高度为10 x 10m,树苗高度为5 x 5m。利用Microsoft Excel等软件对红树林群落结构数据进行了处理。在这项研究中发现了两种类型的红树林,即滨海阿维森尼亚和阿尔巴阿维森尼亚。研究地点的红树林密度被归类为非常密集。根据频率值,在每个观察小区中总能找到阿维森尼亚的类型。优势指数的结果表明,在I站至IV站,有一些类型的优势值范围为0.7至0.78。INP值最高的是阿维森尼亚码头类型,其值为260%,被归类为高。多样性指数值的结果表明,该研究地点的红树林多样性相对较低。而均匀性指数的值则被列入中等及以下的类别。一般来说,水质参数(温度、pH、盐度、基质和基质中的硝酸盐磷酸盐含量)适合红树林生活。

Struktur Komunitas Mangrove di Ekosistem Hutan Mangrove Kecamatan Tayu, Kabupaten Pati
Ekosistem mangrove dapat dimanfaatkan oleh beberapa biota sebagai tempat untuk mencari makan, sebagai tempat memijah dan area asuhan. Kondisi ekosistem mangrove dapat mengalami penurunan salah satunya karena alih fungsi hutan mangrove. Hal ini akan berdampak buruk terhadap perekonomian nelayan, petambak dan masyarakat lainnya pada daerah tersebut. Penelitian ini perlu dilakukan dengan tujuan untuk menganalisis struktur komunitas mangrove yang ada di ekosistem hutan mangrove Kecamatan Tayu, Kabupaten Pati. Penelitian ini menggunakan metode survei dengan teknik purposive sampling untuk penentuan lokasinya. Terdapat 4 stasiun dan setiap stasiun terdiri dari 3 plot, masing-masing plot berukuran 10m x 10m untuk tingkat pohon dan 5 x 5 m untuk anakan. Pengolahan data struktur komunitas mangrove dilakukan dengan menggunakan perangkat lunak berupa Microsoft Excel. Terdapat dua jenis mangrove yang ditemukan pada penelitian ini yaitu Avicennia marina dan Avicennia alba. Kerapatan mangrove di lokasi penelitian tergolong sangat rapat. Berdasarkan nilai frekuensinya jenis Avicennia marina selalu ditemukan pada setiap plot pengamatan. Hasil indeks dominansi menyatakan bahwa pada Stasiun I hingga Stasiun IV terdapat jenis yang mendominasi dengan kisaran nilai sebesar 0,7 – 0,78.

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.
