Abstract: The suitable location of comprehensive park was selected in the accessibility imbalance area. Combined with LA model, the network analysis module of GIS was applied to analyze the accessibility of comprehensive parks in downtown Maanshan based on the characteristics of hilly cities. The results indicated that the distribution of comprehensive park in downtown Maanshan was uneven, dead zone existed in the service coverage; The accessibility deficiency in the southeast of downtown was the most obvious, varying degrees of accessibility deficiency appeared in the northwest and east of the downtown; Six regions met the requirements of arriving the comprehensive park within 25 min on foot, and the conditions was reasonable for comprehensive park construction; Quantifying the comprehensive park accessibility by spatial network analysis with the simulation of actual traffic environment, the distribution of actual accessibility of the comprehensive park was clearly demonstrated.
