| 摘 要： | 本文将划分水团的基本原则,概括为水团内部特征的相对均一性及其与外部海水的明显差异性。用模糊集合讨论了水型、水团和水系等有关概念。提出了用模糊集合观点定义水团及其核心、本体、边界与混合区的建议,并以1979年8月黄海和东海表层为例,给出了各水团的隶属函数。计算了其核心、本体、边界、混合区及贴近度,按其模糊性排出了顺序。

| Abstract: | The fundamental principles of differentiating the water masses may be summarized as the inner relative homogeneity, the outer obvious heterogeneity with others in characteristics. Based on the theory of fuzzy sets, the concepts of the water type, water mass and water system are dealt with. A proposal applying the theory of fuzzy sets to defining the water mass and its core, independent area, boundary and mixing area is put forward.As an example, the membership functions of the surface water masses in the Huanghai Sea and the East China Sea in August 1979 are made. Their cores, independent areas, boundaries, mixing areas and the approach degrees between different water masses are calculated respectively. The order of different water masses is ranged according to their fuzzy degrees. |
