Abstract:
According to remote sensing data，green space accessibility of Nanjing urban area were analyzed using the cost weighted distance method of GIS spatial analysis.The results showed that the overall green space accessibility was good.More than 90% of the urban population could walk to green space in 3 minutes，and the rest need no more than 10 minutes.Attached green space had the best accessibility among green space types.No matter taking of any kinds of transportation，90% of citizens could reach the affiliated green space in 10 minutes.70% of citizens could walk to public green space in 10 minutes.However，the population proportion was 90% with the bicycle or motor vehicle.Ecological buffer green space had the larger service area，but poor service ability for residents.Productive plantation area accessibility was the worst among green space types.In order to improve the service ability，the suggestion which includes increasing affiliated green space area，improving the public green space function，protecting ecological buffer green space and productive plantation area strictly would be put into execution systematically.
