中文摘要：

以容流量及拥挤度等指标进行的空中交通运行评价无法全面反映空中交通的实际运行状况。在依据重要点对航路段进行分组的基础上，通过计算超容比，确定了扇区繁忙时段，基于多项式二次拟合分析了超容比与基尼系数以及泰尔指数之间的数量关系，基于3σ原则确定了不同超容比情况下的理想不均衡度的取值范围。应用方法对厦门1号扇区的实际运行数据进行了计算分析，验证了不均衡度量化方法的适用性。

英文摘要：

The evaluation of air traffic operation such as capacity and traffic capacity and congestion level evaluationcannot fully reflect the actual operation status of the air traffic. On the basis of grouping the route segments in accordance with the important points, the sector busy hours are determined by calculating the excess capacity ratio. Then based on quadratic polynomial fitting, the quantitative relationships between the excess capacity ratio and the Ginicoefficients as well as that between the excess capacity ratio and Theil index were analyzed. Finally,based on the principle of 3σ, the value range of ideal imbalance degree under different ratio of excess capacity calculate and analyze the actual operation data was verified. ratio was determined. This method was then employed to of Xiamen Sector 1, thus, the applicability of this method
