| 摘 要： | １９９２／１９９３中国第九次南极考察队长城站夏季考察期间，对长城湾表层水等无机磷和无机氮营养盐类的月变化特征进行了现场考察。对营养直疃变化的相关民生，营养赴变化与生物活动的关系及与世界其化海域营养盐水平的比较等进行了讨论。结果表明，长城湾夏季表层水营养盐在１月浓度最低，在３月则最高，陆地淡水对湾内营养盐含量的增加没有明显贡献，无机磷与氨氮，硝酸盐氮的变化呈明显的正相关关系；亚硝酸盐始终处于较低的稳

| Abstract: | Using the data from Dec., 1992 to Mar., 1993, the monthly changes of Po4-P,NH:-N, NO,-N and No-N concentrations in the surface water of Great Wall Bayare determined. The correlation between these nutrients, the relations of nutrientschanges with biological activities and a comparison with the level of some baysand off shores in the world are also studied and discussed. The results show thatthe nutrients concentrations were lowest in January and highest in March. Thefresh water from Fields Peninsula had no obvious contribution to the nutrientslevel of the bay. NO,-N maintain a low and stable level. Between Noi-N, NH:-Nand Po4 -P, there were remarkab1e positive correlations.Generally speaking, the nutrients in the surface water of Great Wall Bay kepta high level in austral summer. |
