中文摘要 | 本研究利用附著性矽藻,生菌數及大腸菌類細菌作為污染指標,來評估筏子溪水質 污染程度。沿岸共設九站,分別於七十八年八、十一、十二月各採樣一次。 在筏子溪出現之附著性矽藻共有16屬40種。依Watanabe分類法,其中有九種為好污染種 類,六種為好清潔種類。根據這兩群種類各別之相對數量計算,矽藻群聚指數(DAIpo)介 於21 -44之間。筏子溪河水每一百毫升含生菌數介於1.3x10��-33x10�隊孜﹛A大腸菌類細菌 介於 3.14x10�獺�7.96x10�瓣孜﹛C 以矽藻群聚指數(DAIpo)或生菌數來評估水質,筏子溪皆屬中度污染河川。然而以大 腸菌類細菌來評估,筏子溪水質已受到動物排泄物之嚴重污染。 |
英文摘要 | Attached diatoms, total bacteria count and Coliforms were used to asses the water quality of Fa Tse River. Samples were collected in August November and December 1989, at nine stations along the river. Total 16 genera and 40 species of attached diatoms were found. Nine saprophilous and six saproxenous species were identified according to Watanabe's classification. Diatom assemblage index (DAIpo) of each station, calculated based on the relative abundance of these species, were between 21 and 44. The numbers of total bacteria count per 100ml river water were between 1.3x10�間�33x10��. The numbers of coliforms were between 3.14x10�獺�7.96x10�� per 100ml. Fa Tsa River was considered mesosaprobic when evaluated with DAIpo or total bacteria count. However, the high coliform numbers indicated the river was heavily polluted by animal feces. |
