地铁车站内涝对城市重要设施的正常运行具有破坏性影响，会对乘客和财产造成危害。地铁车站受涝影响因素复杂，评估难度较大。本研究提出一种混合模型，以评估地铁车站的脆弱性，通过集成熵权法（EWM）与技术的顺序偏好的基础上相似的理想解（TOPSIS）（EWM-TOPSIS方法）。该模型是在分析地铁车站易涝性影响因素的基础上建立的。该方法被应用到一个领域的情况下（杭州金沙湖站，发现是脆弱的内涝在IV级）。比较了EWM-TOPSIS法、EWM法和TOPSIS法的结果。EWM-TOPSIS法的结果比EWM法和TOPSIS法更准确可靠。然而，EWM-TOPSIS的可靠性是基于历史数据确定的，不能捕捉快速变化的因素。根据评估结果，提出了促进城市地区整体健康和发展的建议，以实现联合国可持续发展目标11（SDG 11）。
Waterlogging in subway stations has a devastating impact on normal operation of important urban facilities and can cause harm to passengers and property. It is difficult to assess the vulnerability of metro stations to waterlogging because many complex factors are involved. This study proposes a hybrid model to assess the vulnerability of subway stations to waterlogging by integrating the entropy weight method (EWM) with a technique for order preference based on similarity to the ideal solution (TOPSIS) (the EWM-TOPSIS method). The model is based on analysis of factors influencing the vulnerability of subway stations to waterlogging. The proposed method was applied to a field case (Jinshahu station in Hangzhou, found to be vulnerable to waterlogging at level IV). The results from EWM-TOPSIS, EWM, and TOPSIS were compared. The results using the EWM-TOPSIS method were more accurate and reliable than those using EWM and TOPSIS. However, the reliability of EWM-TOPSIS was determined based on historical data, which cannot capture rapidly changing factors. Based on the assessment results, recommendations were made to promote the overall health and development of urban areas to satisfy the United Nations Sustainable Development Goal 11 (SDG11).
