摘　　要：东碇临时海洋倾倒区是当前福建省内使用频率最高、倾倒量最大的海洋倾倒区,自2010年重新投入使用以来,该倾倒区共接纳了约1.5×107 m3的疏浚物,为研究其海底地形冲淤变化情况,利用ArcGIS的空间分析模块、3D分析模块、地统计分析模块等对东碇临时海洋倾倒区进行冲淤变化分析,文中介绍了冲淤分析的基本流程并对分析结果进行讨论,说明疏浚物倾倒对水深地形的影响程度。Dongding Provisional Marine Dumping Site is the one with the highest frequency of utilization and the largest amount of dumping in the Fujian Province. The site has been dumped by 15 million m3 dredged materials since it was put into operation in 2010. In order to study its situation of sediment deposition and erosion, this paper uses the spatial analysis model of ArcGIS, 3D analysis model and geo-statistical analysis model. It also introduces the basic process of the analysis of deposition and erosion, and discusses the result of the analysis to understand how much dumping of dredged materials affects the water depth topography.
