摘要

離岸風力發電是目前全球重要的綠色能源，而台灣海峽擁有的絕佳風力發電環境，其中彰濱外海是可能的場址。但此區亦有多種哺乳類生物出沒在此海域，如保育類動物中華白海豚，如果未能妥善規劃和處理離岸風力機的施工與架設所造成之環境問題，其生存恐會受到威脅。本研究分為二部分:第一是針對離岸風力機施工範圍的風場作水下施工及運轉噪音數值模擬，利用水文模式和歷史海洋地形資料庫，並引用德國Alpha Ventus的風力機施工測量數據來估算聲源強度，分析其水下施工及運轉噪音傳播距離及影響範圍。第二為背景噪音量測分析，放置水下麥克風做長時間量測，分析該海域背景噪音季節性變動值與相關特性。

Today, wind-generated electricity is one of the success green energy in the world. The potential for developing wind energy in the ocean is huge. Absolutely, Taiwan has good condition in developing wind energy. The west ocean of Taiwan is the sites of offshore wind farm. At the same time, this plant also contains lots marine mammals. Therefore, we are easy to neglect the problem between the environment and construction and operation of the offshore wind farm. This research have two parts. The first part is direct to the underwater noise during the construction of the wind farm. And use the construction report of Alpha Ventus in Germany and the historical data of hydrological and terrain to imitate the spreading range and impact range of underwater noise arising from the construction of offshore wind farm. Second part is measurement of the underwater ambient noise. Laying the hydrophone on the sea-bed and measuring the long term ambient noise. To analysis the seasonal variability and the characteristics of the local underwater ambient noise.
