摘要: 本研究採樣區位在台灣中部三條主要河川,大甲溪、大肚溪、濁水溪,的河口,在2001年秋季至2003年冬季從三個樣區各三個不同樣點依季節進行採樣。在野外,以拭鏡紙採集石附生和砂附生矽藻,共觀察得159種矽藻種類,鑑定出其中140種。羽紋矽藻為最常見的矽藻種類。三個採樣區的矽藻種類不同,矽藻種類歸群分析結果可大致分成三群。高美樣區出現的主要附生矽藻種類為Navicula forcipata、Navicula sp. 1、Achnanthese haukiana、Navicula salinicola、Amphora subacutiuscula 、Navicula cryptocephala var. veneta、Navicula sp. 2、Nitzschia libetruhii var. siameis、Navicula augusta、Navicula biseriata、Nitzschia palea、Navicula sp. 2、Navicula jentzii、Coscindiscus furcatus、Stauroneis marina;大肚樣區出現的主要附生矽藻種類為Navicula sp. 1、Amphora subacutiuscula、Navicula augusta、Nitzschia palea、Nitzschia granulata、Navicula sp. 2、Amphirora spp.、Nitzschia constricta、Nitzschia sp. 1、Nitzschia navicularis、Nitzschia libetruhii var. siameis、Achnanthes lemmermannii、Coscindiscus furcatus、Surirella sp. 1、Cyclotella stylorum、Navicula salinicola、Nitzschia hustedtiana、Nitzschia dissipata;漢寶樣區的主要矽藻種類為Navicula sp. 5、Amphora subacutiuscula、Navicula sp. 1、Navicula augusta、Hantzschia marina、Achnanthes hauckiana、Navicula sp. 4、Cocconeis sp.、Amphora staurohyalina、Amphora cingula、Nitzschia sp. 2、Coscindiscus furcatus、Tropidoneis semistriata、Navicula forcipata。這三個樣區僅四種矽藻共同出現,Navicula sp. 1、Amphora subacutiuscula、Navicula angusta、Coscindiscus furcatus。
In this study there are three sampling field located on each estuary of Ta-Chia-Shi, Ta-Du-Shi, and Chuo-shue-Shi. The epipelic and episamic diatoms were collected seasonally from autumn 2001 to winter 2003. A total of 159 diatom species were observed, and 140 species were indentified. Pennate diatoms were generally the most prevalent of them. The diatom communities of each sampling field could be clustered to three groups by using the software Primer 5.0. The dominant diatom species of Kaumei wetland (estuary of Ta-Chia-Shi) were Navicula forcipata, Navicula sp. 1, Achnanthese haukiana, Navicula salinicola, Amphora subacutiuscula, Navicula cryptocephala var. veneta, Navicula sp. 2, Nitzschia libetruhii var. siameis, Navicula augusta, Navicula biseriata, Nitzschia palea, Navicula sp. 2, Navicula jentzii, Coscindiscus furcatus, and Stauroneis marina. The dominant diatom species of Tadu estuary were Navicula sp. 1, Amphora subacutiuscula Navicula augusta, Nitzschia palea, Nitzschia granulata, Navicula sp. 2, Amphirora spp., Nitzschia constricta, Nitzschia sp. 2 , Nitzschia sp. 1, Nitzschia navicularis, Nitzschia libetruhii var. siameis, Achnanthes lemmermannii, Coscindiscus furcatus, Surirella sp. 1, Cyclotella stylorum, Navicula salinicola, Nitzschia hustedtiana, and Nitzschia dissipata. The dominant diatom species of Hanbo wetland (estuary of Chuo-Shue-Shi) were Navicula sp. 5, Amphora subacutiuscula, Navicula sp. 1, Navicula augusta, Hantzschia marina, Achnanthes hauckiana, Navicula sp. 4, Cocconeis sp., Amphora staurohyalina, Amphora cingula, Nitzschia sp. 2, Coscindiscus furcatus, Tropidoneis semistriata, Navicula forcipata. Only four diatom species were common in the three sampling site, Navicula sp. 1, Amphora subacutiuscula, Navicula angusta, Coscindiscus furcatus.
