The close relationship between positive moods and physical and mental health has been revealed, and is believed to have a positive impact on individual health (Dong Yan, 2012). It is predicted that by 2050, the world population will reach 10 billion people, 75% of whom will live in cities, and the density of the urban population will increase (UNFPA, 2011). However, the 21st century is facing a number of health problems such as an increased risk of developing psychological, neurological, and immunological diseases (Danielsson et al., 2012). And prolonged exposure to stressful environments has the potential to exacerbate problems such as attention deficit, anger, and depression (Kanjo et al., 2018). Research has shown that urban nature has the potential to address the health problems of urban dwellers (Keniger et al., 2013), including restoring attention (Kaplans, 1993), reducing stress (Ulrich, 1984), and reducing the risk of death from cardiovascular disease (Hanski et al., 2012). Therefore, improving the natural urban environment is important for maintaining individual health.

The design project is based on a study of the differences in the physical and mental restorative properties of grey, blue and green space types in Guangzhou city for individuals and the differences in the role of specific landscape elements in supporting the restoration of physical and mental health as a preliminary theoretical basis. Based on the results of the study, the Guangdong Province Traditional Chinese Medical Hospital, University City Branch is selected as the practice object to develop an evidence-based landscape enhancement strategy for the site.
