| 摘 要： | 海水中的溶解氧(DO)是影响海洋渔业经济、反映海洋物理化学过程的重要因素。该文依据20世纪90年代末期我国在黄东海海域完成的162个表层海水DO监测数据，利用GIS技术对其进行平面插值拟合，生成该海域DO的四季分布等值线图，据此分析黄东海海域的DO分布和季节变化规律。结果表明：基于太阳辐射导致的海水温度时空差异，影响黄东海DO分布及其季节变化的主要因素是黄海暖流和大陆入海径流。

| Abstract: | The study on the Dissolved Oxygen (DO) in the seawater that affects the sea fishery and reflects some physical and chemical process in the sea is becoming significant.Using GIS,162 investigated DO samples in the Yellow Sea and the East China Sea obtained in 1990s' was analyzed in this paper.Some contours of DO for different seasons were obtained.The distribution and variation of DO in the Yellow Sea and the East China Sea indicates that under the influence of the temperature of the surface sea-water,the warm current in the Yellow Sea plays an important role in the distribution of DO in the winter,while the flow-into-the-sea of the plentiful fresh water from the land controls that in the summer. |
