中文摘要 | 安平港位於臺灣的臺南市,港區開發損毀了被列為臺灣稀有植物的五梨跤(Rhizophora stylosa)生育地。本紅樹林主要復育計畫是在1996年及1998年7月時直插五梨跤胎生苗,惟1996年直插在者在前3年成活率僅有30.5%,1998年直插者成活率亦有相似結果。油污染、藻類危害、家庭垃圾及漁業固體廢棄物為造成死亡率高的主要原因。2000年12月調查1996年直插成活苗木經過4年5個月時間後,生長在全光環境的稚樹高度已達197.2cm,全株乾物重為1861.2g生長速率較生長在海茄苳(Avicennia)樹冠下層者快學8位,而且在栽植第5年後已產生大量胎生苗。1998年直插者亦有相似結果,全光環境的稚樹生物量較遮蔭處者大者5倍。生長在全光環境的稚樹與生長於遮蔭環境者相較,其葉片數及總葉面積高。在生長分析參數方面,葉面積比(LAR)、比葉面積(SLA)、葉重率(LWR)、莖重率(SWR)明顯較低,但提重率(RWR)則較高。 |
英文摘要 | Anping harbour, located at Taiwan City, Taiwan, the harbour construction has destroyed the habitat of Rhizophora stylosa, which are already listed as rare species in Taiwan. The main mangrove rehabilitation project was direct sowing viviparous seedlings in July 1996 and 1998. However, sowed viviparous seedlings in 1996 only attained a 0.5% survival rate during the first 3 years, sowed viviparous seedlings in 1998 has the similar results. Oil pollution, mass algae entangled, garbage and solid waste of domestic and fishery produced such high mortality. In December 2000, i. e. 4 years 5 months after planting, the mean height of sampling sowed in 1996 which grown in full light environment attained 197.2cm, and the total dry weight reached 1861.2 g, a rate of growth nearly 8 times as fast as saplings growing at the site sheltered by the Avicennia canopy. Saplings began to produce many viviparous seedlings 5 years after planting. Propagules sowed in 1998 has similar results, the biomass of sampling grown in full light environment nearly 5 times as much as sapling gown under shade environment. Leaf numbers and total leaf area of saplings gown in full light environment were greater than grown in shad environment. However, in growth analysis parameter, the leaf fare ration (LAR), specific leaf area (SLA), leaf weight ratio (LWR), stem weight ratio (SWR) of saplings were significantly lower than saplings grown under shad environment, but the root weight ratio (RWR) was increased. |
