Study On Functional Spatial Attenuation Of Greenland Recreation In Side Streets

Greenland along the street is an important part of the green open space of the city.It is also an important place for residents to exercise,fitness,recreation and entertainment.It is of great significance to improve the microclimate and the quality of the small environment.Due to its characteristics of wide distribution,flexible layout,and various forms,rapid development has been achieved in recent years.However,problems such as the blindness of planning and design and the lack of consideration of the needs of citizens have also become increasingly prominent.Based on the analysis of domestic and foreign literature,we find that the majority of current studies are based on current research,planning and design methods,spatial distribution patterns,regional cultural characteristics,and internal service facilities.The focus is mainly on the interior of the greenery on the street side,but neglected.The relationship between the function of green space on the street and the external space environment and facilities,as well as the consideration of people's use requirements,has not done much research on the factors affecting recreational functions.Therefore,this study is based on the functions of the greenery around the street.It selects10 greenery areas in the urban area of Hefei as the research object.Through site investigation,the size,form,structure,and elements of the greenery along the street are grasped and the surrounding areas are known.Distribution of catering,commercial,leisure and entertainment service facilities,urban road density,and transportation facilities.Based on this,a questionnaire survey was used to introduce research methods related to geography,tourism,statistics and other related disciplines.The use of greenery along the street was analyzed.The visitors'distance from the park and the frequency of visits were used as a function of recreational functions.Metrics,use of nuclear density method,SPSS regression analysis to determine the characteristics of the spatial attenuation characteristics of street green space recreation functions and the factors affecting the service function of recreational functions,so that the greenery on the street can more effectively play the leading function,better for the city Resident service.Research indicates:?1?There are differences in the interior recreation space,the external service environment,and the transportation facilities characteristics of the greenery on different streets.In terms of internal recreation space,the garden area is between 2650 and 17800 m²,the green area is between 2920 and 15500 m²,the paved area is between 479 and 4050 m²,and garden accessories,landscape architecture,recreational facilities,etc.The density is between 15 and 242?pieces per hm²?;in terms of external service environment and transportation facilities,four different types of service differences and road density are related to the nature and location of surrounding land types.?2?The use of green areas in different streets is diverse in terms of gender,age,occupation,education level and income level.The use time is mainly in the morning?8:00¹1:00?and afternoon?14:00¹7:00?.Time-based,the use of demand for exercise and rest as the main purpose of the tour,the park's main service population is nearby residents.?3?The regression analysis of the function distance attenuation of green space recreation along the street shows that the number of visitors to the garden shows a logarithmic function curve relationship with the Euclidean distance and travel distance variables.The relationship is Y=95.566-14.181log?x?and Y=69.783-9.934log?x?,respectively;the garden visit frequency and the Euclidean distance,travel distance variables show an exponential function curve relationship,and they are all negatively correlated,and the relational expressions are Y=104.455e^-0.004x0.004x and Y=78.401e^-0.003x,respectively.The farther respondents were gradually decreasing in the number of people and frequency of visits.The regression model further shows that the most suitable visiting site for the interviewed population is between 100-350 m from Euclidean and the travel distance is 80-450 m.?4?Using the nuclear density analysis to study the spatial attenuation characteristics of green space recreation function on streetside,the results show that:based on the Euclidean distance analysis,the function of recreation function of different street green areas is not transmitted uniformly in different directions,but presented.Outward development features with different directions and different intensities,more than half of the green space services on streetside are within 400 m.Service directions are mostly densely distributed areas in residential areas,and there are differences in nuclear density values in different directions.KDE value The magnitude of the intensity is related to the frequency of access.The higher the frequency,the higher the KDE value.?5?The SPSS descriptive analysis found that the spatial attenuation of green space recreation function on the street generally shows that respondents have a certain correlation with the Euclidean distance from the park,the frequency of visits,the density of roads around the park,and the average service density.?6?By constructing a multivariate linear regression model between the impact factor and distance and frequency of visits,the analysis results show that different influencing factors have different positive and negative effects on the function of recreational functions of street green space,and have different influence degree and influence.The results further show that:1)When the Euclidean distance is used as a measure of the attenuation of recreational functions,the degree of influence and influence on the Euclidean distance is greater:the paved area of the park and surrounding leisure and entertainment services;2)The travel distance is used as a function of recreational functions.When measuring indicators,the factors that have a greater impact on travel distance are the pavilion area,garden sketch buildings,recreation and entertainment venues,and amusement park area;3)When access frequency is used as a measure of recreational function attenuation,the impact on visit frequency is more The major factors are the surrounding business services,food and catering services,and the gender and age attributes of recreational travelers;4)The impact of the choice of external transportation facilities and the choice of the mode of transport of recreational travelers on the function of recreational functions is not the most important factor.
