广西沿海主要航路规划及通过能力研究

Planning and carrying capacity of major shipping routes in Guangxi

广西北部湾是发展海洋运输业、港口物流业的重要水域。基于2020年海上船舶自动识别系统(AIS)数据,绘制了北部湾水域习惯航路,并借助数理统计方法,对广西北部湾水域习惯航路上21个船舶交通流门线的船舶交通量与交通密度进行分析并提出航路规划建议,同时对航路通过能力进行计算并提出合理化建议。结果表明,北部湾水域船舶航路总体呈现“五干十六支”的基本格局,船舶交汇区内船舶数量大、交通流复杂,需加强重点水域和特殊水域通航风险研究和管理。广西北部湾沿海船舶航路通过能力可满足水域船舶通航现状需求及2035年港口吞吐量规划的需求。研究结果可为广西北部湾海上船舶航路规划、海域使用管理和海洋生态环境保护提供决策支持。

Beibu Gulf of Guangxi is an important water area for the development of marine transportation and port logistics industry.Based on the data of ship automatic identification system(AIS)in 2020,this paper plots the customary shipping routes of the Beibu Gulf waters.With the help of mathematical statistics,it analyzes the ship traffic flow and traffic density of 21 ship traffic flow gateways on the customary shipping routes of the Beibu Gulf waters in Guangxi and puts forward the route planning suggestions.Meanwhile,it calculates the passage capacity of the shipping routes and puts forward reasonable suggestions.The results show that the shipping routes in Beibu Gulf generally present a basic pattern of“five trunks and sixteen branches”,and the number of ships in the ship intersection area is large and the traffic flow is complex,so it is necessary to strengthen the research and management of navigation risks in key and special waters.The navigation capacity of Guangxi Beibu Gulf can meet the current requirements of ship navigation in waters and the port throughput planning in 2035.The research results can provide decision-making support for shipping routes planning,sea area use management,and marine ecological environment protection in the Beibu Gulf of Guangxi.
