Usage And Satisfaction Evaluation Of City Roadside Green Space At Different Temperatures

Greenland along the street is an important part of the urban green space.With the acceleration of urban development,the greenery along the street has played an important role in the construction of the urban ecological environment with its flexible and diverse distribution forms.At the same time,it has also become a hot topic of research today,but many scholars Relevant studies have been conducted on the aspects of planning and design and humanization,and the impact on temperature changes is rarely involved.This paper takes the Hefei City with a specific climate as the research area,and investigates the spatial distribution characteristics of green space landscapes along the streets of Hefei City at different temperatures on the spot.It uses questionnaires to investigate the degree of satisfaction of street greenbelts at different temperatures,and introduces statistics and ecology.The research methods of learning and behavioral psychology,using excel forms and spss23.0 statistical software,analyze the differences in the use and satisfaction of green space along city streets at different temperatures,and explore the use and satisfaction of people in street green space at different temperatures.The main reason for the change in degree.The results show:(1)The users of greenery along the street at different temperatures are mainly middle-aged and older.The number of men is generally more than women.The activities mainly include chess and card entertainment and fitness exercise.When the temperature is low,multiple users are active in the afternoon,and the weekly frequency is reduced.When the temperature is appropriate,the activity time is relatively average and the weekly frequency increases.During high temperature,the activity time is concentrated in the morning and evening periods,and the weekly frequency is reduced.(2)Overall,the degree of satisfaction of the green space beside the street in Hefei City was ranked as suitable temperature> low temperature> high temperature,compared to the number of days with different temperatures in Hefei.High Temperature> Low Temperature> Appropriate Temperature,Long Duration of High Temperature and Low Temperature Duration,The degree of satisfaction is low,the number of suitable temperature days is short,and the degree of satisfaction is high.The contradiction between the two is outstanding.(3)The average degree of satisfaction of street green space at different temperatures is between 3.055 and 3.668,which shows that under certain climate conditions,the planning and construction features of street green space are not obvious,and there is still room for improvement in the overall level.(4)The difference of green space on different streets at the same temperature is significant.Under low temperature conditions,the satisfactory value of green space in each street fluctuates from 2.826 to 4.435,from 3.044 to 4.320 at moderate temperatures,and from 2.134 to 4.019 at high temperatures.Between,the difference in satisfaction at different temperatures exceeds 1.(5)The degree of satisfaction of the greenery on the same street is significant at different temperatures.The degree of satisfaction of the greenery on the street at different temperatures ranges from 0.360 to 1.755 with a large fluctuation range.(6)The correlation coefficients between landscape architecture and skits,recreational facilities,sanitation facilities and satisfaction are all between 0.505 and 0.797 at different temperatures,with R>0.5,indicating a medium-high degree of positive correlation.The correlation coefficient between sidewalk width,supporting facilities and streetside greenbelt satisfaction |R| was between 0.069 and 0.293,|R|<0.3,showing low correlation.(7)At low temperatures,the topography change,green land ratio,paving ratio,seasonal variation of plants,shadow quantity,and streetside greenery satisfaction coefficient |R| are between 0.555 and 0.670,among which topographic changes,paving proportions,plant seasons Phase change and satisfaction are highly positively correlated.Green space rate,shadow volume and satisfaction are highly negatively correlated.At appropriate temperature,the correlation coefficient between each factor and satisfaction |R| was between 0.214 and 0.794,and each factor was closely related to satisfaction.Among them,the correlation coefficient of plant species diversity,seasonal change of plant and satisfaction was R>0.5.Highly positive correlation.Under high temperature,the coefficient of satisfaction of shadow volume,green land ratio,water body and green space on the street was between 0.668 and 0.852,R>0.5,showing a high positive correlation.
