| 摘 要： | 依据香港特别行政区环境保护署于1999—2007年106个航次的调查资料,结合国家海洋局南海分局于1998—2007年10个航次的调查资料,简要描述和分析大鹏湾海水中可溶性无机氮(DIN)和可溶性无机磷(DIP)含量的多年平均分布变化。结果表明,DIN和DIP含量均夏、冬季较高,而春、秋季较低;受香港和深圳等陆源排放影响,四季吐露港西部和沙头角海区域的DIN和DIP含量普遍比其他区域高;夏季南澳养殖场附近水域的DIN也明显较高,可能与养殖场的饵料投放有关。大鹏湾海水中平均氮磷原子比大于16,而DIN和DIP的平均含量分别为0.069和0.009 mg/L。夏季,由于外海高盐水的入侵,底层水中DIN和DIP含量明显高于表层。9 a调查期间,大鹏湾香港海区海水中DIN和DIP含量的年际变化呈较明显下降趋势,而氮磷原子比的年际变化则呈上升趋势。

| Abstract: | The variation of distribution of multi-year average dissolved inorganic nitrogen(DIN) and dissolved inorganic phosphorus(DIP) in the seawater in Mirs Bay were analyzed based on the data obtained from 106 cruises of investigation by Environmental Protection Department of the Government of Hongkong Special Administrative Region from 1999 to 2007 and 10 cruises of investigation by the South China Sea Sub-administration of the State Oceanic Administration from 1998 to 2007.The result showed that both of the DIN... |
