于1994年4月对东海水域二甲基硫面酸（DMSP）浓度进行观测，结合对叶绿素和营养盐的监测结果，分析研究了DMSP分布及其调控因素。结果表明，DMSP浓度范围为0.17-5．66nmol／L，最高浓度出现于410站（125.0°E，29．3°N）。垂直分布浓度最大层出现在表层20m以内。DMSP分布与叶绿素a的分布基本一致，与硝酸氮（NO3－N）的关系在NO3－N浓度小于0.5μmol／L时是正相关，而在NO3－N浓度高于10μmol／L时呈负相关。
In April 1994, the concentration of dimethyl sulfamic acid (DMSP) in the East China Sea was observed. Based on the monitoring results of chlorophyll and nutrients, the distribution of DMSP and its regulation were analyzed. The results showed that the concentration range of DMSP was 0.17-5.66nmol / L, and the highest concentration appeared at 410 stations (125.0 ° E, 29.3 ° N). The vertical distribution of the maximum concentration in the surface within 20m. The distribution of DMSP was consistent with that of chlorophyll a. The correlation was positively correlated with nitrate nitrogen (NO3-N) when NO3-N concentration was less than 0.5μmol / L, but negatively correlated with NO3-N concentration higher than 10μmol / L.
