摘要: 本研究係調查海岸防風林於火燒後,初期植物自然生長情形,以探討火燒跡地自然復育之植物,並提供海岸防風林防火綠帶植物之選擇參據。 經現地植物調查結果,火燒後之植物生長及入侵,一般混交林區比木麻黃純林區快速,且植物種類較豐富。樣區火燒後能夠萌蘗之木本植物包括:苦楝(Melia azedarach L.)、構樹(Broussonetia papyrifera(L.)L’ Herit. ex Vent)、銀合歡(Leucacna glauca (L.)Benth)、黃槿(Hibiscus tiliaceus L.)、蓮葉桐(Hernandia Sonora L.)、馬纓丹(Lantana camara L)、木麻黃(Casuarina equisetifolia L.)、山黃麻(Trema orientalis Blume)、雀榕(Ficus superba Miq. Var.japonica Miq.)等;建議這些樹種可配合相關之防火性植物,共同栽植配置於海岸防火綠帶之中。較耐燃之防火性植物可供林火防災之用,萌蘗型植物則具有火燒復育之功用。 火燒後樣區土壤之pH值、電導度、飽和水力傳導度皆改變。其中火燒木麻黃純林之電導度偏高為1868(μs/cm),使土壤之可溶鹽含量增加,且飽和水力傳導度降為0.014(mm/sec),使土壤滲透性降低,植物在此土壤環境下較不利生長,故應給予適當土壤改良,尤其是木麻黃純林更須營造利於植物生長之環境。 關鍵字:海岸防風林、火燒跡地、植生
Abstract The primary vegetation growth on costal windbreak burned land was investigated in order to find the pioneer species and the best species for growing fire-break trees at the coastal windbreak area. Results indicated that, plants growth and invasion are faster on mixed forest burned land than in monoculture Casuarina forest burned land. Plant species are more abundant on mixed forest burned land. The woody plants which can sprout quickly after burning are Melia azedarach L., Broussonetia papyrifera (L.) L' Herit. ex Vent, Lantana camara L., Casuarina equisetiflolia L., Trema orientalis Blume., and Ficus superba Miq. Var.japonica Miq.. Soil pH, electrical conductivity and saturated hydraulic conductivity were changed after burning. Electrical conductivity of burned Casuarina forest soil is about 1868 µs/cm, and the saturated hydraulic conductivity is down to 0.014 mm/sec. High base concentration and low infiltration rate are unfavorable for plant growth. In order to build a suitable plant growth environment, soil should be amended on forest burned land especial for Casuarina. Key words: Coastal windbreak, Burned land, Vegetation
