Abstract: 1∶5000 aviation image (2014) and urban planning (2012-2030) of Dafeng in Jiangsu province were used as basic landscape data. Based the support of GIS, using buffer analysis, costweighted method and comprehensive analysis of spatial networks, establish the urban park accessibility model and make the evaluation. Results showed that Dafeng′s urban park distribute uneven spatially, only 20% of study area has good accessibility. In these methods, comprehensive analysis of spatial networks shows a higher potentiality with lower rate of deviation.
