摘　　要：本文对１９９７年１１月南沙海区综合考察的标准层资料运用三次样条插值函数法，计算了调查海区的温、盐两种跃层所处的深度及各自的厚度和强度，并进行了相应的分析，特别对季节性温、盐跃层的示性特征，进行了讨论，分析研究发现：所有测站均存在温跃层和盐跃层，其中多跃层超过５０％，跃层的强度和厚度呈相对应的关系，即厚度大（小）的地方强度小（大）。还用连续观测资料对温度日跃层进行了简单的描述，并分析了日温跃层特性与海面气象状况的关系。Based on the data collected during an investigation in the Nansha Islands in Nov. 1997, the characteristics of the transition layer in temperature and salinity are discussed respectively with the interpolating method of cubic spline. The results show that in each observated point of the investigated region there is a thermoc- line and halocline at the same time, and more than half of those are of multitr- ansition layers. The results also show the relationship between the thickness and intensity of the transition layer. The characteristics of the day time thermocline are also discussed.
