| 摘 要： | 为更加全面地分析水域船舶冲突的时空特征,从船舶动态航行过程出发,以船舶领域模型代替船舶碰撞半径,对船舶冲突数据进行识别与提取。通过对空间自相关模型在时间维度上的拓展,探讨船舶冲突数据在时空上的变化特征。基于该模型,研究不同时间尺度下船舶冲突空间变化趋势。实例结果表明,研究水域内的船舶冲突具有较强的空间自相关性,且会随着空间阶的提升而消散。

| Abstract: | In order to analyze the temporal and spatial characteristics of ship collision in waters more comprehensively, starting from the dynamic navigation process of ships, the ship collision radius is replaced by the ship domain model, and the ship collision data is identified and extracted. Through the expansion of the spatial autocorrelation model in time dimension, the variation characteristics of ship collision data in time and space are discussed. Based on this model, the spatial variation trend of ship collision at different time scales is studied. The example results show that, the ship collision in the waters studied is of stronger spatial autocorrelation and dissipates with the increase of the space level. |
