摘要: 
自民國八十四年三月至八十四年十一月,採集了二十一個分布於台灣各地
之碳酸溫泉共三十八個採樣點中之矽藻,共鑑定得矽藻二十三屬七十五種
及十三個變種,並敘述各種及變種之型態特徵;其中包括Achnanthes十種
,Amphora及Caloneis各兩種,Cocconeis、Denticula、Grammatophora及
Cyclotella等各一種,Cymbella十四種,Diatoma兩種,Diploneis四種,
Eunotia五種,Epithemia、Fragilaria及Hantzschia各兩種,Melosira及
Nitzschia各五種,Surirella三種,Gomphonema、Pinnularia等各六種,
Synedra四種,Navicula八種,Rhopalodia及Stauroneis各一種.將矽藻
的屬和種依其在不同二氧化碳含量及不同水溫之採樣點出現與否為依據作
歸群分析(Cluster analysis),得到之結果中,在以不同二氧化碳含量
為依據的分析方面,可將台灣碳酸溫泉矽藻二十三個屬依其出現之二氧化
碳含量範圍分成八群,以種為對象則可將其分成十五個群;而在以不同溫
度為依據的分析方面,以屬為對象可分成十群,以種為對象則可分成十九
群;另外,若以採樣點或溫泉地點為對象作分析,則所得之樹形圖並無明
顯之分群.對照不同二氧化碳含量及不同水溫之採樣點中矽藻分布的情形
,可發現Navicula tripunctata及Nitzschia palea兩種矽藻所出現的採
樣點之二氧化碳含量及溫度範圍皆為最大,在本研究中可視其為對生存環
境中二氧化碳含量及溫度為廣適性的種類;另外,若比較台灣碳酸溫泉中
所觀察到之矽藻種類及國外其他地區所發現者‘i發現有許多相同的種類
;而在本研究中有某些種類之矽藻在許多台灣的碳酸溫泉中皆有出現,在
國外其他地區之溫泉中亦被觀察到,如 Achnanthes exigua,mphora
ovalis及Cymbella affinis等,可能其具有廣大的地理分布.

A study on the diatoms of the travertine springs in Taiwan was
conducted from March 1995 to November 1995. Twenty-one springs
were visited and diatoms samples from thirty-eight stations were
collected. Seventy-five species and thirteen additional
varieties in twenty-three genera have been identified, including
ten species of Achnanthes, two species of Amphora and Caloneis,
one species of Grammatophora, Cocconeis, Denticula and
Cyclotella, fourteen species of Cymbella, two species of
Diatoma, four species of Diploneis, five species of Eunotia, two
species of Epithemia, Fragilaria and Hantzschia, five species of
Melosira and Nitzschia, three species of Surirella, seven
species of Gomphonema and Navicula, four species of Synedra, six
species of Pinnularia, one species of Rhopalodia and Stauroneis.
The description and illustrations of each diatoms are given.
Cluster analysis was used on the basis of presence absence data
to define the relationship between diatom taxa and different
dissolved CO2 gas content. The twenty-three genera of diatoms
can be divided into eight groups, and the eighty-eight species
of diatoms can be divide into fifteen groups. Using the same
method to define the relationship between diatom taxa and water
temperature, the twenty-three genera of diatoms can be divided
into ten groups, and the eighty-eight species of diatoms can be
divided into nineteen groups. However, from cluster analysis the
sampling stations of hot spring showed no obviously group of
diatom taxa in the dendrogram. Navicula tripunctata and
Nitzschia palea can be found throughout the study area with
different CO2 gas content and water temperature. It can be
considered that these two species of diatoms were tolerant
species to CO2 gas content and water temperature of the
environment. Diatom communities inhabiting the travertine
springs in Taiwan possess similarities with which inhabiting hot
springs in other countries. Especially, Achnanthes exigua,
Amphora ovalis and Cymbella affinis have been found all over the
world.
