    中文摘要:
          基于2006-2007年在南黃海冷水團海域開展的4個季度月的調查資料, 重點研究了該海域溶解氧(DO)、葉綠素a(Chl a)最大值現象和營養鹽累積的季節演變規律。結果表明:春至秋季黃海冷水團海域DO和Chl a最大值層深度具有先加深后變淺的趨勢, 出現最大值層的海域面積呈現出先增大后縮小的變化過程, DO和Chl a最大值層的深度及面積在夏季均達到最大, 至冬季DO和Chl a最大值現象消失;夏季冷水團海域深水區DO最大值處的氧含量整體高于春季, 而冷水團邊界附近氧最大值處的氧含量整體低于春季;春至秋季冷水域深水區次表層Chl a最大值處的Chl a含量先降低后升高, 于夏季時最低, 入秋后開始升高, 而一年四季中冷水域邊界附近Chl a最大值處的Chl a含量卻在夏季時最高, 而且顯著高于深水區。黃海冷水團海域的底層營養鹽儲庫具有一定的空間異質性, 冷水域底層通常分別在深水區和西部邊界處存在營養鹽高值核心, 其中位于深水區的高值核心位置季節變化不明顯, 而位于冷水域西部邊界附近的高值核心位置則呈現出自春季至夏季向西移動、入秋后又向東部移動的季節變化特征。水文物理因素和生物化學過程對DO、Chl a最大值及營養鹽儲庫的季節演變具有重要的調控作用。
    英文摘要:
          Based on the data obtained in four seasonal surveys during 2006-2007 in the southern Huanghai (Yellow) Sea Cold Water Mass area, the seasonal evolution of dissolved oxygen(DO), chlorophyll a(Chl a)maximum phenomena and nutrient accumulating process was analyzed.The result showed that:(1)From spring to autumn, the depth of DO and Chl a maximum layer had the trend of deepening first and then shallowing, the scope of DO and Chl a maximum layer increased firstly and then decreased, the depth and scope of DO and Chl a maximum layer were the largest in summer;the DO and Chl a maximum phenomena disappeared in winter.(2)In DO maximum layer in the deep waters of the cold water mass in summer, DO concentration in summer was higher than in spring, while in DO maximum layer in the boundary area of the cold water mass in summer, DO concentration in summer was lower than in spring.(3)From spring to autumn, Chl a concentration in Chl a maximum layer had the trend of decreasing firstly and then increasing, and it was the lowest in summer;in Chl a maximum layer located in the frontal region of the cold water mass in summer, Chl a concentration in summer was the largest all the year round, and was much higher than in deep waters.(4)The nutrient storage in the bottom cold water mass area of the southern Huanghai Sea had spatial heterogeneity, generally, there was a high-concentration core of nutrients in the deep waters and the boundary region of the cold water mass area respectively, the one situating in the deep water had the fixed position on the whole all the year round, while the one located in the boundary region of the cold water mass moved westward from spring to summer, and then moved eastward again when autumn was coming.(5)Hydrological factors and bio-chemical effect played an important role in regulating the seasonal evolution of the DO and Chl a maximum phenomena as well the nutrient storage.
