A Study On Urban Street Green Justice In Beijing

Urban green space can create ecological and social benefits,and is an outdoor recreation,entertainment and aesthetic place for residents.However,under the background of rapid urban transformation,the distributive injustice of green space has become a social problem recognized by scholars and governments at home and abroad.The previous study on green justice mainly has three shortcomings: first,they pay more attention to race,income and age,but less to gender differentiation;second,based on the potential green space accessibility in residential area can't reflect the justice of individual actual green perception during daily travel;third,there is a lack of study on the mechanism behind green injustice.In this thesis,we develop a new method to comprehensively study urban steet green jusitce and socio-spatial differentiation.The combination of individual daily travel and street green view will be the quantitative method of travel quality,and the study on socio-spatial differentiation of gender will be the theoretical basis of street green justice.With the help of street view image recognition technology,the green value of streets in the Sixth Ring Road of Beijing was obtained.We analyze 7880 travels from 662 respondents in the Shangdi-Qinghe Region,Haidian District,Beijing,exploring the green view differences between different groups,as well as the preferences of gender travel modes and green choices.The results indicate that the travel green view of Beijing suburban residents vraies by different social demographic structure and travel characteristics: Women prefer to choose high green view quality,multi-threaded,short-duration and short-distance travel modes,under a disadvantage in green view index and green view speed.Groups with Hukou,married and driver's license can enjoy better green experience during daily travel.Education and income don't show consistent results as expected,while high educated people limit their travel green view due to the preferences of telecommuting and online shopping.Car travel has the highest green view index and speed,followed by public travel,and active travel had the best average green value.visiting relatives and friends and commuting can acquire more green,on the contrary,green view index of schools,leisure places and consumer places is lower,which are performed to have better street green view.The disadvantages of household labor division and social resource acquisition force women to face double pressure from household and employment responsibilities.Long-term multiple role play results in women being good at multi-functional "bundling" ability,and they are more likely than men to travel with caregiving tasks.In addition,women's aesthetics of the natural environment and fear of crime help them choose green and safe travle routes,so that they enjoy green space as much as possible in a limited time and distance.Urban planning,landscape architecture and traffic design need more feminine perspective,considering the gender differences of travel modes and green perception,improving the living quality of women,and promoting social justice.
