平原區濁水溪流域浮游動物群聚結構時空變異與水質評估應用
Spatial Structure and Temporal Variation of Zooplankton Community and Ecological Assessment of Water Quality in Plain of Jhuoshuei River
摘要
濁水溪是台灣最長的河川，特點是有高懸浮微粒，為特殊的水生生物棲地。本研究季節性調查濁水溪探討浮游動物相與環境因子（水溫、pH、鹽度、飽和溶氧量等）。建立1,037筆32種淡水浮游動物資料，以輪蟲類22種、原生動物8種為最多樣，橫足類豐量最高。ANOSIM結果顯示，下游河段群聚結構與中游、上游顯著不同；群落結構有季節性變化。與物種的季節性的生活史有關。濁水溪水中的浮游動物以秋季的下游豐富最高，每公升可達12,056個。輪蟲類是各季節與各河段樣本中的優勢優勢無脊椎動物。根據輪蟲類作為生物指標的水質指數Q_(B/T)，濁水溪上、中游河段均屬寡養型水體；下游夏季為中養型水體（Q_(B/T)用 = 1.0），秋季為優養型水體（Q_(B/T) ＞ 2.0），冬季族群量過低，無法評估。
並列摘要
Jhuoshuei River is the longest river in Taiwan and is a special habit for aquatic organisms because high river sediment content. In this study, we investigated the zooplankton fauna and environmental factors, such as water temperature, pH, salinity, TDS and saturated DO of Jhuoshuei River seasonally. In total, 1,037 metadata of 32 zooplankton species were established. There were 22 species of rotifera and 8 species of protozoan. Copepods was the most abundant taxon. Downstream zooplankton community structure showed significant difference with upstream and midstream by ANOSIM analysis. ANOSIM analysis suggested that communities had seasonal variations. It was related to their seasonally life history. The highest richness of zooplankton (12,056 inds/L) occurred at the downstream in autumn. Rotifers was the dominate invertebrates in all samples. Based on the Brachionus-Trichocerca quotient (Q_(B/T)) of Rotifers biological index (Q_(B/T) ＜ 1), the upstream and midstream water quality of the Jhuoshuei River was at oligotrophic state whereas downstream water was mesotrophic (Q_(B/T) = 1.0) in summer, eutrophic (Q_(B/T) ＞ 2.0) in autumn. The Q_(B/T) was not able to evaluate because of the low population of the rotifer.
