A Study on the Impact of Blue-green Space on Human Mental Health

Abstract

As attention to human mental health issues increases, and research on the related effects of blue-green space (BGS) in the residential environment increases, it is meaningful to study and analyse this impact from multiple perspectives. One purpose of this article is to systematically classify and summarize this impact. Therefore, this article integrates the research and conclusions of multiple documents. The results show that for humans of different ages, the mental health affected by BGS generally follows the environmental-physiological-psychological mechanism. Among them, the elderly is mainly affected by the improvement of social interaction brought by BGS. Young people are mainly affected by the alleviating effects of indoor blue and green factors on various stresses. In addition, landscapes with high green vision rate and low blue vision rate and natural landscapes have positive benefits for the restoration of perception in mental health, and this benefit is also affected by the season. Based on the analysis and summary, suggestions related to urban greening and landscape construction can be obtained, which can play a positive role in the construction of healthy cities in the future.
