| 摘要: |
| 文章构建海州湾海岸侵蚀风险评价指标体系，运用层次分析法确定指标权重，并运用ArcGIS进行风险等级划分。研究结果表明：灌南区的燕尾港海岸侵蚀风险最大，属于风险等级中的侵蚀段；赣榆区的青口镇以及青口盐场地区、连云区的猴嘴镇属于风险等级中的微侵蚀段；灌云区的台北盐场和徐圩镇沿岸属于风险等级中的稳定段；赣榆区的马站、柘汪、海头镇、九里乡和连云区的墟沟镇海岸侵蚀风险最小，但淤积现象严重。该研究可为海洋管理部门治理海岸侵蚀提供参考。 |

| Abstract: |
| Coastal erosion and coastal deposits are currently occurring in the coastline.It has some negative impacts on coastal environment and habitat.This paper constructed the risk assessment system of coastal erosion in Haizhou Bay，and computed the weight of each indicator and made effective assessment of coastal erosion in Haizhou Bay by using ArcGIS.The research results indicated that there was the greatest coastal erosion risk in Yanwei harbor area，there was slight coastal erosion risk in Qingkou of Ganyu district，Qingkou salt area，and monkey mouth town in Lianyun District，there was no coastal erosion risk at Taibei salt area and Xuwei coast，while there was serious deposit risk at Mazhan，Zhewang，Haitou and Jiulixiang of Ganyu district，and Xugou coast of Lianyun district.It has important significance for relative marine management departments to harness coastal erosion. |
