中文摘要 | 在成立大鵬灣國家風景特定區管理處後,維護生物多性棲地及優質景觀生態美學是成功的道要條件。故本研究主要目的是透過因子分析方法瞭解本海域在蚵架及箱網養殖拆遷前後水質特性及其變異。將水樣經實驗分析的結果利用主成份因子分析方法以說明顯著的潛在因子。結果顯示大鵬灣海域水質環境最主要的潛在因子為「洋流引起因子」、「初級生產力影響因子」及「養殖污染引起因子」。而總體測值在蚵架暨箱網養殖拆遷補償後,大鵬灣潟湖水質從以往受嚴重優養化趨勢而有大大改善之跡象。然基於環境地形特色之故,本海域在囊袋未端處仍有水體水質優養化之慮,解決改善之道可作一水理模擬驗証後,考慮於西南端另作一出入口,透過加強洋流及交換能力以改善水質惡化。藉此因子分析方法可瞭解在蚵架暨箱網養殖業拆遷前後之水質特性,期望此些方法及結果對生態保育及決策管理上能有所幫助。 |
英文摘要 | After constructed the Tapeng Bay National Scenic Area, the most important things is to maintain an ecological aesthetics of high quality view and a high habitat’s biodiversity. This work investigated water samples collected from Tapeng Lagoon. Factor analysis was performed to explain the characteristics and variation of water quality during taking the oyster frames and fishery boxes aquaculture apart. The result shows that the most important latent factors in Tapeng Lagoon are the ocean causes factor, primary productivity influence factor, and fishery pollution cause factor. The water quality gets better after taking the oyster frames and fishery boxes aquaculture apart. On the basis of environmental topography characteristic reason, making another entrance and exit way through ocean is the best way to raise the water quality in Tapeng Lagoon especially for eutrophication. These methodologies and results can provide useful information concerning habitat recovery and management in Tapeng Lagoon and may be applicable to other estuarine habitats with similar properties or experiencing similar environmental issues. |
