中文摘要 | 表面流人工溼地(SFCWs)可提供多項生態功能,為常用於溼地異地復育的方法。生態系統服務評估雖有助以公眾認同的價值標準客觀地量化生態功能與判斷人工溼地的重要性,但目前仍缺乏完善的SFCWs生態系統服務評估方法針對溼地於生物多樣性與棲地品質之價值作評估,故本研究以北臺灣兩座SFCWs為研究地點,探討以聯合國千禧年生態系統評估(MA)所計算的生物多樣性支持服務價值能否反映臺灣SFCWs於棲地品質與生物多樣性的重要性。研究結果顯示兩研究SFCWs為臺灣多種鳥類包括2種保育類和5種臺灣特有種的棲地及候鳥重要的過境棲地,同時水生底棲大型無脊椎動物之生物多樣性相似於其他國外自然及復育溼地,證實兩研究SFCWs在生物多樣性支持服務的重要性。然而MA的評估結果卻顯示,兩研究SFCWs在生物多樣性支持服務的價值偏低,只佔生態系統服務總價值<10%。因MA的方法主要建基於全球生態系統之物質與服務的供應(global assessment),並不適宜直接套用於氣候、環境與生態條件獨特的臺灣溼地。本研究提出目前溼地生態系統服務評估值得改善之處,主張依據MA的架構,針對熱帶與亞熱帶海島型國家的溼地發展亞全球,性評估(sub-global assessments),以準確評估臺灣的溼地生態系統服務價值,協助建立相關的人工溼地管理政策。 |
英文摘要 | Surface flow constructed wetlands (SFCWs) which have commonly used as the off-site mitigation measure for the degraded and loss of wetlands, have been developed to serve for multiple ecosystem functions. Ecosystem functions can be quantified by monetary values using ecosystem service assessment to enhance public recognition, and we can determine the importance of const ructed wetlands based on the values of ecosystem services they provided. Biodiversity supporting services is one of the key ecosystem services of SFCWs. However, the biodiversity and habitat quality valuation of wetlands are generally underdeveloped in the current assessment of ecosystem services. Therefore, in this study, we conducted biodiversity survey in two SFCWs in the northern Taiwan and valuated the biodiversity supporting services based on Millennium Ecosystem Assessment (MA) aiming to determine if MA could reflect the importance of habitat quality and biodiversity in Taiwan SFCWs. Our results showed that the two study SFCWs were important habitats for many birds in Taiwan including two protected species and five endemic species. Also, these two SFCWs located along the important migratory pathway for migratory birds. The biodiversity of benthic macro invertebrates of our two study SFCWs was similar to other natural and restored wetlands in different parts of the world. Despite the importance of biodiversity supporting function of these two SFCWs, their monetary values of biodiversity supporting services as calculated by MA was relatively low «10% of total values). Therefore, it could not be appropriate to use this MA method based on global assessment directly to assess wetlands in Taiwan which is characterized by unique climatic, environmental and ecological conditions. Hence, we proposed some improvement measures of the current MA, and advocated that Sub-Global Assessments for wetland ecosystem services should be developed for tropical and subtropical islands. Thus, this can allow derivation of a more accurate and objective ecosystem service assessment system for Taiwan wetlands and provision of important insights on the policies of constructed wetlands management in Taiwan. |
