中文摘要：

以1996—2008年的连云港海域表层海水温度、盐度的日观测数据为基础,运用多重分形分析方法对该海域温度、盐度的时间演变特征进行了研究。结果表明,在所研究的时间尺度内,温度和盐度均具有统计标度不变性,表现出较弱的多重分形特征;多重分形谱形态参数的计算结果表明,温度和盐度的变化均存在着下降的趋势,并且盐度随时间变化的复杂性、不规则性和不均匀性要较温度显著。研究结果对于连云港海域海洋环境系统动力过程的理解和预报模式的改进具有参考意义。

英文摘要：

method was used to analyze the temporal variability of Lianyungang coastal SST and salinity based on the daily monitoring data from 1996 to 2008.Results showed that SST and salinity in the study area demonstrated a weak multifractal behavior with scaling invariance in the investigated period.And the parameters of multifractal spectrum reflected that both SST and salinity changed with a downward trend and the temporal variation of salinity had much more complexity,irregularity and inhomogeneity than that of SST
