摘要

摘要: Ramos GB、Panduyos JB、Caray RE、Bacquial LS.Ramos GB, Panduyos JB, Caray RE, Bacquial LS.2024.揭开沿海多样性的面纱:菲律宾 Surigao del Sur 海滩森林植物区系的清查和保护报告。Biodiversitas 25: 421-430.由红树林和海滩森林树木组成的沿海绿化带在减轻灾害和抵御气候变化方面起着举足轻重的作用。尽管这些沿海生态系统的重要性显而易见,但由于缺乏有关物种群落结构及其更广泛生态重要性的综合数据,它们在研究中往往被忽视。因此,本研究旨在记录菲律宾南苏里高省部分沿海城市的海滩森林组成和保护状况。这项研究在五个取样点进行,即拉巴斯、比尔阿特、巴利巴顿、波布拉钦-卡格韦特和阿兰加萨岛。在每个取样点,都建立了一条与海滩海岸线平行的 2 公里横断线,横断线上有 100 平方米的取样地块,间距为 50 米。对海滩物种频率计数、百分比和多样性指数进行了量化。研究记录了隶属于 21 科 25 属的 27 种海滩森林物种,主要物种为 Crinum asiaticum、Cocos nucifera、Millettia pinnata、Timonius compressicaulis 和 Terminalia catappa。阿朗加萨岛和拉巴斯海滩森林的物种多样性最高(H' = 2.04);然而,卡格韦特的物种丰富度最高(Margalef = 2.34)。这项研究有可能大大有助于解决菲律宾海滩森林物种方面现有的数据缺口。由于基础设施建设和人类活动造成的迫在眉睫的物种灭绝威胁,这项研究的成果是对行动的紧急呼吁;因此,在这些物种面临灭绝威胁之前,地方政府部门、学术界和社区应共同努力保护这些物种。
