摘　　要：随着航班量的增加终端区拥堵频发,对异常密度交通流的识别成为研究热点。针对上述问题,论文依据终端区高峰期航迹数据,采用高斯核密度分析的方法,对空中交通高密度区域进行可视化分析,揭示了终端区拥堵的时空演化规律,为空中交通拥堵的缓解及优化方向提供参考依据。将采集的高峰期的终端区航迹数据,通过地理信息软件ArcMap的高斯核密度生成成都终端区交通流密度图进行分析。结果表明:高峰时段的高密度运行区域均处于6扇与7扇交界处,以天府机场为起点,经过航路点ZGA在6扇与31扇最右交界处结束,高密度交通流整体走势向东北方向发展。对高密度交通流分布规律的挖掘可提高管制员对终端区拥堵态势把握的准确性与科学性。With the increase of flight volume terminal area congestion occurs frequently,the identification of abnormal density traffic flow has become a research hotspot.Aiming at the above problems,this paper adopts the method of Gaussian kernel density analysis based on the peak period trajectory data of the terminal area to visualize and analyze the high-density area of air traffic,re⁃vealing the spatio-temporal evolution law of congestion in the terminal area,and providing a reference basis for the alleviation and optimization direction of air traffic congestion.The collected terminal area aerial track data during peak hours are analyzed by gener⁃ating a traffic flow density map of Chengdu terminal area through Gaussian kernel density of geographic information software Arc⁃Map.The results show that the high-density operation areas during peak hours are all at the junction of sector 6 and sector 7,start⁃ing from Tianfu Airport and ending at the rightmost junction of sector 6 and sector 31 after the waypoint ZGA,and the overall trend of the high-density traffic flow develops in the northeast direction.The mining of the distribution pattern of high-density traffic flow can improve the accuracy and scientificity of the controller's grasp of the congestion situation in the terminal area.
