近岸海域營(yíng)養(yǎng)鹽濃度不斷增加,富營(yíng)養(yǎng)化成為全球普遍現(xiàn)象。開(kāi)展富營(yíng)養(yǎng)化評(píng)價(jià)方法研究并應(yīng)用于實(shí)際水體的富營(yíng)養(yǎng)化狀態(tài)評(píng)估,可為富營(yíng)養(yǎng)化防控和海洋環(huán)境管理提供支持。本文對(duì)中國(guó)福建省廈門灣的營(yíng)養(yǎng)鹽動(dòng)態(tài)變化及其影響因素進(jìn)行綜合分析。同時(shí)采用多種方法評(píng)估富營(yíng)養(yǎng)化狀態(tài)的時(shí)空變化。研究時(shí)間范圍是2011-2018年春、夏和秋季的水質(zhì)參數(shù)和營(yíng)養(yǎng)鹽濃度,空間上分為九龍江河口、廈門西海域、東海域、南部海域、同安灣和大嶝海域等不同海域。富營(yíng)養(yǎng)化評(píng)價(jià)方法包括營(yíng)養(yǎng)鹽指數(shù)法、潛在性富營(yíng)養(yǎng)化評(píng)價(jià)法、營(yíng)養(yǎng)狀態(tài)指數(shù)法(TRIX)和HELCOM富營(yíng)養(yǎng)化評(píng)價(jià)法(HEAT 3.0),其中HEAT 3.0最初用來(lái)評(píng)估波羅的海的富營(yíng)養(yǎng)化狀態(tài)。本文參考九龍江流域-廈門灣生態(tài)系統(tǒng)管理戰(zhàn)略行動(dòng)計(jì)劃中制定的水質(zhì)目標(biāo)和海水水質(zhì)標(biāo)準(zhǔn)(GB 3097-1997)進(jìn)行評(píng)價(jià)。研究結(jié)果顯示廈門灣不同海域和季節(jié)的營(yíng)養(yǎng)鹽濃度有顯著差別。春季和秋季的無(wú)機(jī)氮(DIN)和活性磷酸鹽(DIP)濃度高于夏季。廈門島周邊海域,包括廈門西海域和南部海域、同安灣和九龍江河口區(qū)的營(yíng)養(yǎng)鹽濃度高于其它海域。鹽度和營(yíng)養(yǎng)鹽(無(wú)機(jī)氮、無(wú)機(jī)磷)濃度以及鹽度與富營(yíng)養(yǎng)化評(píng)價(jià)指數(shù)之間均有顯著的...
