随着城市化进程加快和全球气候变暖，城市内涝日益频发。通过广泛的文献综述，构建了由17个指标组成的城市内涝脆弱性评价指标体系，采用博弈论组合赋权法对江苏省13个地级市的城市内涝脆弱性等级进行了评价。结果显示：大暴雨次数、第三产业增加值、地均GDP、人口密度、城镇化率、不透水率和人均道路面积是评估城市内涝脆弱性的关键指标；经济的快速发展和相对落后的城市建设理念，是影响城市内涝脆弱性的重要原因；江苏省南部地区最容易受到城市内涝的影响，其次是中部和北部地区。文章最后提出了有效缓解城市内涝灾害的策略。
Abstract：With the acceleration of urbanization and the effects of global climate change, urban flooding has become increasingly frequent. Based on an extensive literature review, a vulnerability index system comprising seventeen indicators was constructed to assess urban flooding vulnerability in thirteen prefecture-level cities in Jiangsu Province. The combination weighting method based on game theory was applied to determine the vulnerability levels. The results indicate that torrential rainfall frequency, value added of the tertiary industry, GDP per unit land area, population density,urbanization rate, impervious surface ratio, and per capita road area are key indicators in evaluating vulnerability.Rapid economic development coupled with relatively outdated urban planning concepts are major factors contributing to urban flooding vulnerability. The southern region of Jiangsu is the most vulnerable, followed by the central and northern regions. The study further proposes targeted strategies to help mitigate urban flood risks and enhance resilience in vulnerable regions.
