The Correlation Study Of Shenzhen Greenway Usage And Spatial Grandient Variation Of Built Enviroment

The greenway is an important part of the urban ecosystem,and it is also a linear activity space for public rest and body building.Greenway research for 30 years,the first 20 years of design of the greenway,people gradually began to pay attention to the greenway useage,the research proves that the built environment influence people’s behavior,and then affect the use of the green way.People entering the greenway Greenway in the vertical direction,the vert ical direction spatial gradient changes of greenway construction environment influence the greenway useage,however,greenway surrounding built environment is not homogeneous,explore the specific changes of the built environment on green way use less.This paper carries on the analysis from the perspective of green way useage,through the empirical study in Shenzhen city greenway,explore the relationship between the using efficiency and the built environment gradient change,how the built environment changes can attract more people to use,to attract more diverse types of activities,reveal the pattern and construction strategy of using green road peripheral space.In this study,GIS was used as the research tool.Firstly,the data of the activity distribution,intensity and diversity of the greenway network in Shenzhen were presented by the data of outdoor slow-motion physical activity and Shenzhen greenway.The spatial gradient characteristics of the greenway within 300 meters were counted by the gradient value of 50 meters.The correlation between the use of the greenway and the spatial gradient characteristics of the surrounding environment was analyzed by cross analysis,and the correlation between them was analyzed.Internal mechanism.The resu lts show that there are four types of indicators: preference environmental index,dependent environmental index,anaerobic environment index,non-preference environmental index.Preference environmental index include: residential landuse,commercial service landuse,green landuse,government community landuse,development intensity,building density,population density,dependent environmental indicators include: street density,bus density,road landuse,NDVI.Through the empirical study,it is found that the surrounding environment of greenways with gradually changing characteristics is more attractive for outdoor slow-moving activities: in greenway planning,Environmental indicators Traffic road land,in the direction away from the greenway gradient of su ch land to reduce the green space to ensure that 50 m around the gradient in the rich road network to improve the accessibility of the Green Road,in t he green space around 150 m Gradient to improve the preference built environment indicators can better serve the greenway users in the 300 m space gradient to reduce the built environment indicators of disgust,greenway can ensure the greenway environment and security,through research and analysis can be drawn above The control principle and the constructio n strategy of the built environment around the greenway.
