Title: | 水田排水量與水質對於附近濕地生態之影響 | Authors: | 張文亮 | Keywords: | 濕地生態;水質;排水;滲漏;Wetland Ecology;Water Quality;Drainage Water;Percolation | Issue Date: | 1998 | Publisher: | 臺北市:國立臺灣大學生物環境系統工程學系暨研究所 | Abstract: | 濕地是自然界最複雜的生態系統,而 其穩定性受周圍土地使用情況所影響。本 研究主要以台北市的關渡濕地為例,濕地 東邊的水田排水,目前是濕地淡水的主要 來源,是影響該區域生態的重要因子。本 研究經現場調查試驗水田排水的水文與水 質特性、土壤理化特性、濕地植物的種類 及其覆蓋度。將分析之結果以統計的因子 分析,判斷影響濕地的顯著特徵因子為鹽 份、營養鹽及工業廢水。並由水質及土壤 理化特性的濃度分佈曲線了解關渡濕地土 壤逐年鹽化較嚴重為中央渠道二側之土 壤,淡水源水質劣化而水澤優養化影響東 側之淡水濕地。 Wetland is one of the most complex ecological system in natural world, however, maintenance a wetland stability for a long period in conflict with landscape development in surrounding. Drainage is main low-salt water resource for Kuan-Du wetland. The purpose of this study is to investigate drainage water quantity and quality, soil physical and chemical properties, and wetland plants Therefore, factor analysis shows that impact factors on wetland ecology from drainage water are nutrients, salt and industrial wastes. As concentration distribution result, salt effect around main channel and eutrophication impacts wetland ecology on east side. |
