Urban floods are the most severe disaster in most Chinese cities due to rapid urbanisation and climate challenges. Recently, media data analytics has become prominent in enhancing urban flood resilience. In this study, news media data from the GKG of the GDELT project was innovatively used to examine the pattern of news media responses towards urban flooding in China's Sponge City Programme (SCP) pilot cities. We find that public sentiments toward urban flood events have been more positive in SCP pilot cities from 2015 to 2021. News media responses towards urban floods exhibit strong seasonality, which is significantly connected with rainfall patterns. Most of the media articles were posted during the urban flood event. Finally, we suggest the opportunities and challenges in applying GKG data analytics and new technologies for urban flood resilience. The results can provide beneficial references to urban flood management strategies in China's Sponge Cities for associated policymakers and stakeholders.
由于快速的城市化和气候挑战，城市洪水是大多数中国城市最严重的灾害。最近，媒体数据分析在提高城市洪水韧性方面变得突出。在这项研究中，创新性地使用了 GDELT 项目的 GKG 媒体数据来研究中国海绵城市计划（SCP）试点城市中媒体对城市洪水的反应模式。我们发现，2015 年至 2021 年期间，SCP 试点城市公众对城市洪水事件的情绪更为积极。媒体对城市洪水的反应具有很强的季节性，与降雨模式密切相关。大多数媒体文章都是在城市洪水事件期间发布的。最后，我们提出了在应用 GKG 数据分析和新技术以提高城市洪水韧性方面的机遇和挑战。研究结果可为中国海绵城市的城市洪水管理策略提供有益的参考，为相关政策制定者和利益相关者提供参考。
