中文摘要 | 本研究挑選臺大實驗林90~91年度執行崩塌地整治工程143件為樣本,嘗試以植生重要值指標、鳥類多樣性指標及水棲昆蟲群聚結構指標等評估崩塌地治理效益。植生重要值指標以24個地面樣區依據工法不同分成4種,綜合觀之演替植生在本區以五節芒(Miscanthus floridulus)、台灣蘆竹(Arundo formosana)、山黃麻(Trema orientalis)為普遍及優勢之植生,目標樹種以相思樹(Acacia confuse)、台灣赤楊(Alnus formosana)復育情況較佳,台灣櫸(Zelkova serrata)成效不佳;整體而言目標植生之復育情況尚屬良好,並隨不同工法間而有差異。鳥類多樣性分析顯示北勢溪流域比陳有蘭溪流域多;初步分析調查得知各區崩塌地面積大小與出現之鳥種及數量有關,但與崩塌地治理工法及工程有無損壞相關性不高。有關水棲昆蟲群聚部分,共採獲26科32分類群(taxa),蜉蝣目(Ephemeroptera)及毛翅目(Trichoptera)的種類為最多,其次為雙翅目(Diptera);歧異度值介於1.94-2.03;均勻度值介於0.63-0.69。除第1站科級生物指標水質為良(Fine),其餘樣站皆為好(Good)水質。 |
英文摘要 | We collected 143 landslide rebuilt cases that were restored between 2001 and 2002 at Experimental Forest of National Taiwan University to evalute the restoring effectiveness by using biological investigation. Important vegetation index (IVI), birds diversity index (BDI), and aquatic insect community parameters index (AICPI) were applied for biological investigation. Our data showed that major vegetation in landslide rebuilt are Miscanthus floridulus、Arundo formosana、 Trema orientalis. The performance of silviculture of Acacia confusa and Alnus Formosana silvicultures were better than Zelkova serrata. BDI at BeSer creek watershed was berrer than Chenyolan creek. However, BDI was not different with different technics and construction situation, while BDI could be differed with the size of landslide area. We collected 26 families and 32 taxa aquatic insects, mainly in Ephemeroptera and Trichoptera. Aquatic insect diversity was 1.94-2.03, and evenness was 0.63-0.69. Water quality assessed by aquatic insects biotic index was at good scale for most landslide rebuilt cases, except site 1 at fine scale. |
