摘要

Abstract

The fundamental principle for differentiating water masses is a strict consideration of their “relative interier homogeneity” and obvious exterior differences with others in characteristics. The conceptions of water type

water mass and water system are dealt with on the basis of the theory of fuzzy sets. A proposal to apply the theory of fuzzy sets to define the water mass and its core

independent area

boundary and mixing area is put forward. As an example

the membership function of the surface water masses in the Yellow Sea and East China Sea in August

1979

are considered. Their cores

independent areas

boundaries

mixing areas and the approximation degrees between different water masses are calculated respectively. The water masses are ranged according to their fuzzy degrees.
