離岸風力發電目前為我國推動再生能源重點項目之一。其潛力場域分布於臺灣西部 海域,而該海域同時也是重要沿近海作業漁場之一。為瞭解離岸風機設置對海域環 境、漁業資源的影響,於風機場域所在之臺灣海峽海域進行海洋環境調查、底拖網 試驗及當地漁業資源現況調訪。臺灣西部海域受季風及海流影響,冬季大陸沿岸流 南下,帶來低溫低鹽水,同時也帶來高營養鹽,春季水溫回升,浮游植物吸收營養 鹽,而夏季浮游動物豐度增加,葉綠素濃度低。浮游生物分布及其食階關係與其攝 食來源有關。且彰化地區漁獲生物種類超過130種,包含魚類、甲殼類及頭足類等類 群,為當地常見之種類,周年均可捕獲。顯示臺灣海峽受季風及季節性海水交替 ,使彰化離岸風電海域出現高度的海洋生物多樣性。

研究報告摘要(英)


Offshore wind power is one of the important developing renew energy in Taiwan. The potential wind farms are distributed in the waters of western Taiwan. The zone is the important coastal fishing ground in Taiwan. We investigated the marine environmental factors, the bottom trawl study, and the fishery survey to understand the effects of the marine environment and fishery resources with the installation of the offshore wind turbines in Taiwan Strait. The monsoon and current affected the marine environment in western water of Taiwan. China Costal Current brought the water mass which was low temperature and low salinity, and carried the rich nutrients in water. In spring, seawater temperature became higher. Phytoplankton absorbed the nutrients, and the concentration of chlorophyll a increased. The richness of zooplanktons increased in summer, and chlorophyll a decreased. The relation of trophic levels is interrelated to the food. It is exceeded 130 kinds of the fishing species including fish, crustacean, and cephalopod etc. in Changhua offshore. They were common species, and fished all year. Above the result, it showed high biodiversity occurred in the sea of Changhua offshore wind farms by the monsoon and seasonal currents.
