Impact Of Plant Environment On Human Health In Healing Gardens

Healing garden has great significance on human health. Plant environment is the main mediumof the garden for psychological treatment to reduce pain and to improve health of the patients. It canimprove the research and guide the practice of healing garden in our country to study impaction ofthe garden plant environment on human health. Three sanatoriums (Wu yunshan Sanatorium,Qianjiang Sanatorium and PLA Sanatorium)in Hangzhou were taken as an example to research theimpaction preliminary, so as to discuss the relationship between plant environment and human health,as well as promoting the theory research and practice on healing garden.Species of plants in the three sanatoriums were investigated. The plants were classified by theirornamental characteristics. People would have a preliminary understanding to sanatorium plantenvironment by analyzing the plants’ ornamental characteristics and season landscape. Then,people’s satisfaction to the sanatoriums were analyzed by an evaluation group,which was composedby twenty volunteers in Zhejiang Agriculture and Forestry University and ten volunteers in eachsanatoriums. Finally, the effect of plants in the three sanatoriums on human health was studied bytesting brain wave, blood pressure, heart rate and skin conductance and using mental scale of POMSto measure human mood. Besides，some plant environment，which had obvious effect to promotehuman health, were screened out.1) The plants in the three sanatoriums are very rich, and Hangzhou native plants holdoverwhelming superiority of them in each nursing homes. Foliage and flowers plants are more thanother kinds of trees classified by ornamental characteristics. The proportion of flowers, foliage, fruitand branches plants are:30%，45%，13%and13%in Wu yunshan Sanatorium;32%,43%，14%andl0%in Qianjiang Sanatorium;9%,46%，14%and10%in PLA Sanatorium. More than95%people satisfy with the plant environment in the sanatoriums. However, the complacence gets lowerand lower as the seasons changed from Spring to Winter.2) Plant environment can reduce the human body blood pressure and heart rate effectivelywhen compared with hard paving environment. And the effect of plant environment on reducinghuman blood pressure and heart rate is remarkable in Summer and Winter. Human brain wave aremainly influenced by the appreciation of the plant landscape. And the brain wave will be changedmore if the plant landscape become more beautiful‘. Neither ct nor P ‘was influenced by plantenvironment significantly. However, a ’/g ’ got totally significant influence from plant environment. Plant environment is a good stimulation to reduce human body skin conductance.3)Plant environment promotes human health by improving positive emotions and reducingthe negative emotions. There is no obvious difference in boys’ and girls’ emotions, which wasinfluenced by plant environment.4)When the ecological performance and appreciation of plant environment are better, theeffects on human health are more obvious and the beneficial to human health becomes moresignificant.
