摘要:
为判断泉州湾海岸线变迁所处的状态,引入分形分析法,对泉州湾海岸线的分维值进行计算.采用时间序列上的泉州湾海岸线数据,运用海岸线分形网格计算方法,计算了泉州湾总体海岸线及各分岸段海岸线分维数,分析了总体海岸和各分岸段分维数变化过程,并试探地将分维变化值的大小作为判断海岸线冲淤严重程度的依据.结果表明:泉州湾海岸线可用分维作其良好的表征参数;从海岸线分维值的变化趋势可判断出海岸线变迁是否处于动态平衡中的稳定状态,泉州湾分维变化幅值大于0.035,表示海岸线冲淤程度严重.
Abstract:
With the introduction of fractal analysis, the fractal dimension of Quanzhou Bay coastline is calculated, to determine the state of Quanzhou Bay shoreline change. According to time series data, based on the coastline fractal grid method, the coastline fractal dimension of overall Quanzhou Bay shoreline and branch coast Quanzhou Bay shoreline is discussed, the change process of the overall coastal and sub-coastal section fractal dimension is analyzed, the value variation of the fractal dimension is tentatively regarded as a judgment based on the severity of coastline erosion. The results show that: the fractal dimension is a benign characterization parameters of Quanzhou Bay shoreline; whether coastline change is in dynamic equilibrium steady state or unstable state can be judged by the trend of the fractal dimension change of the coastline; the variation of amplitude of the fractal dimension of Quanzhou Bay is greater than the magnitude of change0.035, indicating the degree of shoreline erosion and siltation is serious.
