To investigate the potential change in the value of greenery due to increased time spent near homes during the COVID-19 pandemic, this study examined whether the relationship between green spaces within walking distance from homes and mental health has changed before and during the pandemic. Additionally, the study explored the potential shift to nonmaterialism during this period, assessing how this change in mindset might have influenced the relationship between greenery and mental health. According to our analysis, in March 2017 (before the pandemic), green spaces around residential areas showed a positive correlation with mental health for up to approximately 50 % green coverage rate; beyond this threshold, a negative correlation was observed. The analysis of March 2021 (during the pandemic) showed that green spaces around residential areas had a positive correlation with mental health for 0 % to approximately 50 % green coverage, similar to the findings of March 2017. However, unlike 2017 results, no negative correlation was observed beyond 50 % green coverage. Accordingly, we conclude that during the pandemic, people living in areas with relatively higher green coverage had better mental health compared to pre-pandemic levels. Additionally, a comparison between March 2017 and March 2021 indicated a general shift towards less materialistic attitudes. This shift might have contributed to mental health improvement during the COVID-19 crisis. If the trend toward nonmaterialistic thinking continues to rise over the long term, the benefits derived from green spaces are expected to increase.

物质主义背景下的绿色空间与心理健康：COVID-19 大流行前后的比较分析


为了调查在 COVID-19 大流行期间由于在家附近花费的时间增加而导致的绿色植物价值的潜在变化，本研究检查了离家步行距离内的绿色空间与心理健康之间的关系在大流行之前和期间是否发生了变化。此外，该研究探讨了这一时期向非物质主义的潜在转变，评估了这种心态的变化如何影响绿色植物与心理健康之间的关系。根据我们的分析，在 2017 年 3 月（大流行之前），住宅区周围的绿地与心理健康呈正相关，绿化覆盖率高达约 50%;超过此阈值，观察到负相关。2021 年 3 月（大流行期间）的分析表明，住宅区周围的绿地与心理健康呈正相关，绿色覆盖率为 0% 至约 50%，类似于 2017 年 3 月的调查结果。然而，与 2017 年的结果不同的是，在 50% 的绿色覆盖率之外没有观察到负相关。因此，我们得出结论，在大流行期间，与大流行前的水平相比，生活在绿色覆盖率相对较高的地区的人们的心理健康状况更好。此外，2017 年 3 月和 2021 年 3 月之间的比较表明，人们普遍转向不那么物质主义的态度。这种转变可能有助于在 COVID-19 危机期间改善心理健康。如果非物质主义思维的趋势长期持续上升，那么绿色空间带来的好处预计将增加。
