以江苏近海调查取得的冬季和夏季ADCP、CTD数据为基础,利用GIS方法分析了江苏近海水温的平面分布特征,并在Arcgis平台上绘制了江苏近海海流的矢量图,以此对江苏近海的水温、海流等海洋物理要素的时空分布特征和相互关系进行了综合分析。结果表明,江苏近海物理环境可以分为3大区域:废黄河口以北的北部海区,中部辐射沙洲海区和南部长江口附近海区。 Based on the winter and summer ADCP and CTD data obtained from Jiangsu offshore survey, the paper analyzed the planar distribution of water temperature near the sea in Jiangsu by using GIS method. On the Arcgis platform, the vector diagram of the offshore flow in Jiangsu Province was drawn. Based on this, , Ocean currents and other marine physical elements of the spatial and temporal distribution characteristics and the relationship between a comprehensive analysis. The results show that the coastal physical environment of Jiangsu Province can be divided into three major areas: the northern sea area north of the waste Yellow River estuary, the radiation sandy sand sea in the middle part and the sea area in the south of the Yangtze Estuary.
