中文摘要 | 本文藉由 1989 年秋季至 1991 年春季兩年內的野外調查,對曾文水庫垂直斷 面理化水質、浮游藻類和若干環境因素的季節性變化進行研究。夏季與冬季因物理翻轉現象 使溫度垂直方向分佈均勻,由實測資料發現 1989 年之秋、冬季,水庫上游有大量營養源氮 、磷流入水體中,水庫之表層與中層水含高濃度之氮和磷,使得藻類密度有迅速增加之趨勢 ,浮游生物大部份集中於表層水體中。且與 TP/TN 水質污染之比值有良好線性關係,當 TP/TN 比值超過 0.14,即有藻類急速增加之趨勢。 |
英文摘要 | After sampling analysis from August 1989 to Spring 1991 for vertical water quality, variations of plankton and environmental factors in the Tseng-Wen reservoir were investigated. The difference in water temperature between the surface and bottom is minimized during summer and winter due to overturn. According to the investigation, with respect to a large many nutrient inflow to the reservoir in August 1989 and Winter 1989, the N and P concentration of surface and middle water increased. The response of the reservoir was an increase of plankton. The major majority of the plankton is condensed in the surface water. The concentration of chlorphylla has a linear relationship with the proportional TP/TN ratio in the Tseng-Wen reservoir. It is noteworthy that a reservoir with an TP/TN ratio greater than 0.14, may lead to an increase in algae growth. |
