摘　　要：随着海上交通日益繁忙,保障船舶安全航行成为全球性重要议题。本文从航行自然环境和海上交通环境两方面构建航行环境风险评估模型,将地理空间技术和模糊层次分析法(fuzzy analytic hierarchy process,FAHP)结合,对厦门港及其周边海域的航行环境风险评估,形成风险分级图并对其空间分布特征进行分析。结果表明:受自然环境影响,该区域航行环境风险大致呈“U”型分布,风险等级沿“SW—NE”逐渐降低;在交通环境影响下,风险等级≥8级的区域呈散点状分布在距海岸线较远海域,尤其是兄弟屿东部海域;综合以上两方面,厦门港及其周边海域航行环境风险整体处于中等偏低风险,但仍有约6.17%的区域风险等级≥7级,主要分布在“南澎列岛—兄弟屿”连线的延长线以南和厦门湾海域。As the maritime traffic gets increasingly busy,ensuring the safe navigation of ships has become an important global issue.A risk assessment model of navigation environment from natural and maritime traffic is proposed in this paper.To evaluate the navigation risk of Xiamen Port and its surrounding areas,this study combines geographic space technology and fuzzy analytic hierarchy process(FAHP),forms the risk classification map and analyzes its spatial distribution characteristics.The results show that:Affected by the natural environment,the navigational environmental risks in this area are roughly distributed in a"U"shape,and the risk level gradually decreases from southwest to northeast.Under the influence of the traffic environment,the areas with risk greater than 8 level are scattered in the seas far from the coastline,especially in the eastern sea area of Brother Island.Taking the above two aspects into account,the overall risk of the navigation environment in Xiamen Port and its surrounding sea areas is moderately low.However,nearly 6.17%of the sea areas of Xiamen Port and its surrounding areas have the navigation risk greater than level 7,which is mainly distributed in the south of the extension of the“Nan Peng Islands-Brother Island”line and the Xiamen Bay waters.
