Abstract: In order to make the renovation of country parks爷public facilities more reasonable and scientific, this paper analyzes the problems of public facilities in Dongshen Bajia Country Park using the post occupancy evaluation method and space syntax. For public facilities in country parks with a relatively wide scope of service radius, the service radius can be smaller than that of scenic parks, but greater than that of city parks. For public facilities with a relatively small scope of service radius, the service scope of the tour lines of high integration can be smaller than that of city parks, while the service scope of tour lines of low integration can be made greater than that of city parks
