紅樹林底棲生物棲地模式之建立

Study on the Benthic Invertebrates Assessment Model for Habitat Restoration in Mangrove Wetland

摘要


海岸紅樹林濕地是重要的生態系,有很高的生態生產力。更具有野生動物棲息、避免海岸侵蝕、消化污染物和水質淨化等功能。在台灣彰化芳苑一帶,農業廢水排入海岸潮間帶導致嚴重污染。本研究以芳苑紅樹林為研究地點,調查期間為2006年6月至2007年5月,共進行五季次調查,建立芳苑紅樹林濕地之底棲生物的棲地模式,找出影響底棲生物多樣性的關鍵性棲地因子,以作為未來在生物多樣性的考量下,棲地污染自淨和生態復育營造之參考。研究結果顯示酸鹼度(pH)、總磷(TP)、底質酸鹼度、總有機物及底質耗氧量等因素為重要影響因子。

並列摘要


Coastal wetlands are important ecosystems because of their high biological productivity and role as habitat for wildlife, shoreline protection from erosion, pollutant removal and bioremediation, and water quality purify. The agricultural waste discharged into the coastal wetlands led to coastal pollution in the intertidal zone at Fangyuan area in Taiwan. Twelve sampling sites were monitored during the study period from June 2006 to May 2007 in Fangyuan mangrove wetland. The establishment of Habitat Assessment Procedure (HEP) for Fangyuan mangrove wetland. Bioremediation of polluted habitat enhancement to create a reference in the biological diversity concept. The results showed that pH, total phosphorus (TP), sediment pH, total organic matter and sediment oxygen consumption have important influencing factors by HSI.
