Study On Relationship Between The Use Of Urban Green Space Of Urban Residents And Their Health

The history,applications and main methods of urban green space and urban residents'health were summarized on basis of urbanization status, the environmental, economical and social problems cased by urbanization, and the affects of urbanization on urban inhabitants's health. The different scales, categories urban green space and urban residents were selected as the object of study, and the relation between the use of the urban green space and the urban residents's health was studied through 3 sub-research. The methods of questionnaire survey, human physiology, psychology, quality of life were used in this study. The results indicated:(1) The urban green space's planting condition obviously effected the urban green space service condition.The use frequency of the bad planting condition green space was often low (less than 1~2 times per week) , the service distance is unreasonable (more than 500m) , residents' use demand could not be satisfied, the evaluations were not high. Lacked the enough time to use the urban green space, the nearby urban green space area to be too small, the urban green space far away from their home were the obstacles preventing people from using urban green space(77.87%). The purposes of urban residents use the green space were similar, that were breathing the fresh air(29.74%), relaxing mood and alleviating pressure(45.26%). 81.90% of the urban residents said that their physiological health and mental health were improved.(2) The urban green space's use has had the remarkable influence to resident's physiological health. The results of the change of 8 physiology indexs and the POMS of the urban residents indicated: After they used the urban green space, the means of the Finger temperature raised 0.82℃, Oxygen saturation raised 0.81%, Skin conductance reduced 2.10μS, RR interval reduced 0.08s, means of heart rate, Max of heart rate, Min of heart rate reduced 3.25bpm, 5.32bpm, 7.23bpm, VE reduced 0.84 L/min. The results indicated that the residents'physical condition were improved, their body became more comfortable.(3) The urban green space's use has had the remarkable influence to resident's mental health. For the resident who used the urban green space carried on the psychometry through the POMS, the results indicated: The mean of the POMS of the residents reduced 25.19 after they were used the urban green space, the mood condition remarkable changed for the better, the mood were stabler, the pressure were alleviated and the mental health condition were improved. The urban green space use frequency and the residents'mental health had the remarkable correlation, the residents whose using frequency were high, their mental health were obviously better, the POMS of whose using frequency are 1~2 per month and 1~2 per year have had no obviously difference. We suggested residents to use green space more than 1~2 per week to obtain the better metal health. Moreover, The residents whose demand were satisfied that their mental health were obviously better than others.(4) The urban residents who lived in the different planting condition had the remarkable different quality of life. PF, BP, MH, RE, SF of who lived in the bad planting condition were obviously lower. Live under the exposed environment residents had the bad physiological health, mental health, social compatibility and quality of life than who lived in good planting condition, moreover its health condition are become worse.
