金門地區海藻資源調查
一、研究緣起
金門沿岸受到大陸沿岸流較冷水團的影響，可見到溫帶地區較大型之海藻種類，如海帶等，此與台灣本島沿岸屬於亞熱帶或熱帶地區的海藻相有明顯差異。由於過去受到海岸的管制，金門的海藻種類與資源分佈並未完整建立，僅散見於金門海域之環境影響評估報告中，無相關的資料可供查詢，因此藉由此金門海藻調查計劃，調查金門海岸潮間帶的海藻種類，以增加金門地區藻類生物多樣性的物種。
二、研究方法及過程
自民國97年04月01日起至民國97年12月31日，每季(4、6、9、11月)在金門地區的金寧鄉、金沙鎮、金湖鎮、金城鎮、烈嶼鄉等五個地區海岸的潮間帶進行採集一次，共四次。在金門選定調查樣點後，配合潮汐的變化進行採樣，採集時以工具或徒手將藻類由附著的岩石上採下，亦配合浮潛或水肺潛水方式於潮間帶進行採樣工作，並記錄種類且拍照存檔，同時作採集地的GPS 定位。採集所得之新鮮海藻洗淨後放入冰櫃中帶回實驗室，一部份海藻放入5-10%的海水福馬林(5-10%formalin/seawater)固定做成浸液標本，一部份乾製成臘葉標本，做為日後形態觀察之用。做海藻鑑定種類時以新鮮標本為主，浸液標本與臘葉標本為輔，於解剖顯微鏡下觀察，依據外部形態特徵比對鑑定之。
三、重要發現
本研究於民國97年04月01日起至民國97年12月31日，於每季(4、6、9、11 月)在金門地區的金寧鄉、金沙鎮、金湖鎮、金城鎮、烈嶼鄉等
五個地區15個海岸的潮間帶進行海藻種類與分布之調查，共四次。採集地點為大金門的北山斷崖、馬山、青嶼、山后、田埔、峰上、料羅灣、翟山、塔山、建功嶼、慈湖等海岸，小金門的林邊、東林、上林、東崗海岸。採集調查結果，共有57 種海藻，其中以紅藻24 種最多，綠藻18種次之，褐藻14 種，藍綠藻1 種最少。物種數量以4 月最多有31 種，6月次之27 種，11 月最少13 種，海藻的種類在4 月到11 月之間有逐漸遞減的趨勢。就地點而言，大金門以田埔的種類數最多22 種，青嶼及料羅灣次之有17 種，北山斷崖及山后最低5 種；小金門以東林最多17 種，東崗次之15 種，以林邊最少4 種。
其中有11 屬具有經濟價值，例如Ulva、Codium、Endarachne、Sargassum、Corallina、Chondracanthus、 Gloiopletis、Gracilaria、Grteloupia、Hypnea、Porphyra 等可用於健康食品、醫藥、飼料、肥料、工業方面。在四次採集中，大金門的具經濟海藻物種數以田埔最多16 種，青嶼及料羅灣次之分別為13 種，山后2 種最少；小金門的具經濟海藻物種數以東林最多12種，東崗次之11種，林邊最少4種。
Abstract
1、The origin of study
We can find large seaweeds which are grown in the temperate zone is because of the continental coastal flow through the Kinman area. It shows remarkable difference between the tropical and the temperate zone when Taiwan is belongs to subtropical and tropical zones. Since littoral area has been to restrain, the species of seaweeds and resource distribution is not establish completely. Since littoral has been to restrain we can only see few data in some environment effect estimate reports. The category and distribution of seaweeds has not established completely. Due to those reasons we research inter seaweeds and concern the diversity of this area.
2、 Methods and progression
We sampling seaweeds which growth on shoreline from April 1 to December 31 2008, once per season (April, June, September, November). There are four times. There are fifteen sampling sites along coastline. Sampling sites are Peishan、Mashan、Chinyu、Shahou、Tianpu、Fongshun、Liaolo harbor、Chuh Mountain、Shuitou、Kincheng、Tsu lake、Linpan、Tonlin、Shanglin、Jiugong Harbor. First, pick up sampling site along shoreline in Kinman. Secondly, sampling time is to coordinate with tide. Use tools or hand and recreational diving to sampling seaweeds, which are attach reef. Record GPS of each sampling site and take photographs on every species of seaweeds. Seaweeds are washed and put into refrigerator then transport back to laboratory. Some seaweeds lay at 5-10% formalin/seawater to been fixed, the others are herbarium specimen for morphology observation. Take parts of fresh samples and preserve it in 95% Ethanol. Fresh sample is priority when we identify species under stereomicroscope, fluid specimen and herbarium specimen auxiliary.
3、Important findings
We observed 57 species seaweeds in Kinmen, Rhodophycophyta includes 24 species, Chlorophycophyta are 18 species, Phaeophyta are14 species and Cyanophyta only 1 specie. Total species is 31 In April. In June are 27 species less than April, besides November only 11 species. The abundance of seaweeds is progressively decreasing from April to November. Concern about site we can discover that the most abundance area is Tianpu. There are 22 species were observer here. We are found 5 species of seaweeds at Peishen and Shahou. There are 17 species at Tonlin, 15 species at Tonkung and 4 species at Linpan, Lieyu village. Some of these species have economy value, for example Ulva、Codium、Endarachne、Sargassum、Corallina、Chondracanthus、Gloiopletis、 Gracilaria、Grteloupia、Hypnea、Porphyr, they can exploit for healthy foods, medicine, forage, fertilizer and industry. Since Kinman is a national park it build up not only preserve historical landmarks and maintain traditional community but also biodiversity. In Tianpu show the highest biodiversity, Seaweeds which are taken here is not often seen in Taiwan.
