臺灣形狀狹長，中央山脈南北縱列，河川多呈東西向分佈，坡陡、流急是其主要特色。在水文條件上，北臺灣受季風影響，終年有雨；中、南臺灣降雨集中在春、夏，主要降雨來源為梅雨、颱風，因此河川在豐、枯水期間流量懸殊。巴氏銀鮈 (Squalidus banarescui) 為本研究目標物種，主要棲息於烏溪中下游段辮狀河川，其棲地於2023年、2024年豐水期受一系列洪水脈衝影響，對於棲息於辮狀河川的魚類而言，洪水脈衝所帶來的水文動態變化，是形塑棲地環境與魚類群落組成的主要因子。本研究聚焦烏溪流域中下游段辮狀河川的洪泛平原棲地，首先整合前人研究結果，同時增加濱水植生覆蓋率調查，基於模糊理論進行魚類棲地建模，藉以建立量化棲地品質評估系統，並在後續分析上輔以功能特徵、統計方法，探討在一系列洪水脈衝影響下，豐、枯水期間巴氏銀鮈棲地品質變化、與棲地內魚類群落的關聯性及棲地魚類群落組成。
研究結果顯示濱水植生覆蓋率、底質、水面寬、地表水及伏流水溶氧、地表水濁度，於巴氏銀鮈幼魚與成魚棲地品質具有顯著影響力。適度的濱水植生覆蓋率（5% ~ 15%）能有效提供魚隻利用，水面寬則為決定枯水期棲地續存條件。在各研究水域中，本研究發現溪尾大橋五號具備能支持巴氏銀鮈各生命階段生存的棲地條件，是巴氏銀鮈得以於此續存的主因；溪尾大橋二號則在2024年枯水期作為育幼所，提供幼魚生長。在功能特徵與統計方法上，巴氏銀鮈與具相似功能特徵之魚種（如中華花鰍）出現特性存在高度正相關；而在威脅方面，亦可能受到吳郭魚的潛在競爭與被捕食的壓力。豐、枯水期魚類群落變化中，典型對應分析與k-平均演算法說明部分魚種只在豐水期被紀錄且個體數量稀少，進一步驗證洪水脈衝促進魚類遷移與組成變化之理論。

Rainfall in central Taiwan is concentrated in spring and summer, resulting in significant flow differences between wet and dry seasons. This study focused on the central Taiwan gudgeon (Squalidus banarescui), which inhabits the floodplain habitats of the braided river sections in the mid-lower Wu River, and its habitat was influenced by a series of flood pulses during the wet seasons of 2023 and 2024. A fuzzy logic-based fish habitat model was developed to establish a quantitative assessment system for the habitat quality of S. banarescui. In addition, functional traits and statistical analyses were employed to investigate the spatiotemporal dynamics of habitat under flood pulses and their relationship to fish communities.
The results indicated that the cover ratio of riparian vegetation, substrate, wetted width, dissolved oxygen, and turbidity significantly affected the habitat quality of juvenile and adult S. banarescui. A moderate cover ratio of riparian vegetation (5% ~ 15%) supported habitat utilization, while the wetted width maintained habitats during the dry season. S. banarescui was strongly associated with species sharing similar functional traits (e.g., Cobitis sinensis). Notably, Zone 5 at Xiwei Bridge supported both life stages of S. banarescui, serving as a refuge for the species' persistence. Zone 2 at Xiwei Bridge also functioned as a nursery during the dry season of 2024. Seasonal movement in fish communities, identified by canonical correspondence analysis (CCA) and k-means clustering, supported the hypothesis that flood pulses drove fish movement and community restructuring.
