The worldwide coronavirus disease 2019 (COVID-19) pandemic has seriously affected not only physical health but also mental wellbeing (i.e mental stress and suicide intention) of numerous urban inhabitants across the globe. While many studies have elucidated urban parkland enhances and mental wellbeing of urban residents, the potential for parkland to mitigate mental health burden imposed by the COVID-19 has received no attention. This nationwide study systematically explored the association between parkland, the COVID-19 pandemic situation and mental wellbeing from 296 cities in China. The study innovatively used big data from Baidu Search Engine to assess city-level mental wellbeing, thereby enabling comparisons among cities. The results show that the provision of parkland is positively associated with mental wellbeing during the COVID-19 epidemic. For COVID-19-related indicators, the geographical distance to Wuhan city, work resumption rate, and travel intensity within the city are also positively associated with mental wellbeing, while the number of COVID-19 infections and the proportion of migrants from Hubei Province for each city are negatively associated with mental wellbeing. Last, the most important finding is that parkland reduces the negative effect of COVID-19 on mental wellbeing during the COVID-19 epidemic. To achieve the goal of promoting mental wellbeing through urban planning and design during the future pandemics, policymakers and planners are advised to provide more well-maintained and accessible parkland and encourage residents to use them with proper precautions.
全球2019冠状病毒病（COVID-19）大流行不仅严重影响了全球众多城市居民的身体健康，还影响了他们的心理健康（即心理压力和自杀意念）。虽然许多研究已经阐明城市绿地能增强城市居民的心理健康，但绿地减轻COVID-19所带来的心理健康负担的潜力却未受到关注。这项全国性研究系统地探讨了中国296个城市的绿地、COVID-19疫情形势与心理健康之间的关联。该研究创新性地使用百度搜索引擎的大数据来评估城市层面的心理健康状况，从而能够在城市之间进行比较。结果表明，在COVID-19疫情期间，绿地的提供与心理健康呈正相关。对于与COVID-19相关的指标，与武汉市的地理距离、复工率以及城市内部的出行强度也与心理健康呈正相关，而每个城市的COVID-19感染病例数和来自湖北省的移民比例与心理健康呈负相关。最后，最重要的发现是，在COVID-19疫情期间，绿地减轻了COVID-19对心理健康的负面影响。为了在未来大流行期间通过城市规划和设计实现促进心理健康的目标，建议政策制定者和规划者提供更多维护良好且易于到达的绿地，并鼓励居民在采取适当预防措施的情况下使用它们。
