A Study On The Relationship Between The Spatial Pattern Of Green Space And The Physical And Mental Well-Being Of Residents In Old Town Of Hangzhou

Urban green space is one of the urban landscapes coupled with artificial and natural.It is an important part of improving the living environment of residents,and it is also an effective way to improve the physical and mental health of residents.Constructing a reasonable and scientific urban green space system can not only optimize the urban ecological environment,but also improve the physical and mental health,well-being and well-being of residents.This paper discusses the spatial layout of green space in the old city of Hangzhou and the impact of green space on the well-being of residents in order to build a scientific and reasonable urban green space system.The article uses the interpretation of remote sensing satellite images to obtain the distribution map of green space in Hangzhou’s old city;through the comparative analysis of the number and area of urban green space within the unit range of the European-style distance buffer and the network distance,the advantages and science of the network distance method are proved.The population density is used as the resistance to calculate the network distance of the nearest green space in the residential area based on the urban road network;a questionnaire survey was conducted on 665 residents in the old city of Hangzhou,and the use of seemingly uncorrelated regression was applied to the physical and mental well-being of residents.The influencing factors and degree of happiness satisfaction are analyzed.The results show that:(1)The impact of green space layout and utilization on the physical and mental well-being of residents: Within three times of weekly play,4-6 times have a linear increase in the well-being of residents,but there is no significant relationship for more than 6 times;In the time of a single play of green space,less than 1 hour and 1-3 hours are directly proportional to the mental health and well-being of residents,but a single play of more than 3 hours shows no significant relationship;the greater the number of green spaces within 1000 meters of network distance,the green area The larger the area,the higher the sense of well-being,but the relationship does not appear in the range of 500 meters and 1500 meters;the smaller the value of the nearest green space from the residential area,the higher the well-being;(2)individual attributes and The impact of personal perception on the physical and mental well-being of residents: 30-45-year-olds who have a good understanding of the role of green land have higher physical and mental well-being than other residents;the more attractive the destination,the higher the physical and mental well-being of the residents.In addition,residents’ physical well-being and mental health well-being have a significant positive effect on residents’ satisfaction with happiness,that is,the higher the physical well-being,the higher the residents’ satisfaction with happiness;the higher the residents’ mental health and well-being,the residents’ satisfaction with happiness The higher the degree.It is worth noting that the degree of green space utilization and geographic space have a greater impact on residents than individual attributes and personal perceptions.There is no obvious relationship between the spatial pattern of green land and the physical and mental benefits of residents in the five old urban areas of Hangzhou,and the impact of green land on the physical and mental well-being of residents It will not change with the level of the residential area.Urban residents pay more and more attention to urban green space,and constructing a reasonable green space system is conducive to improving residents’ physical and mental health,well-being and satisfaction from the perspective of ecological environment.In order to construct urban green space based on the spatial layout status and residents’ well-being needs,we can start from the three aspects of increasing the number of street green spaces,reasonably expanding the green space area,and increasing accessibility,to draw the urban green space development map of the old city of Hangzhou.
