中文摘要：

基于复杂网络模型，构建了机场飞行区风险演化数学模型以及风险演化拓扑结构模型，从聚类系数、平均路径长度、度分布对机场飞行区风险演化数学模型进行了阐述，从入出度、节点子网数、所含支链数对风险演化拓扑结构模型进行了分析，并提出了风险断链控制方案。结论表明，飞行区安全管理制度漏洞、员工安全培训缺乏、地面工作人员安全意识缺乏及违规操作、恶劣天气是机场飞行区风险演化模型的关键节点。

英文摘要：

Based on the complex networks model, a mathematical model and a topology model of risks evolution in airport flight area are constructed. The analyses of the mathematical model conclude clustering coefficient, average path length and degree distribution. The analyses of the topology model conclude in-degree, out-degree, node subnet number and the contained branched numbers. The control scheme of risks chain scission is proposed. The results show that safety management system vulnerabilities in airport flight area, lack of employee safety training, the ground staff security awareness and illegal operations and the lack of inclement weather are the crucial nodes of risks evolution model in airport flight area.
