%X The disaster prevention function of urban parks plays a role in disaster prevention, refuge, rescue and reconstruction when the city is faced with disasters. Taking 32 urban parks with the function of disaster prevention and hedging in Yuhang District as the research object, the spatial layout of urban parks in the research area was analyzed by using the road traffic network accessibility and facility service area analysis tool of ArcGIS. The results showed that the distribution of urban parks in Yuhang district was concentrated in the east and south, and the number of urban parks in the northwest was small. Under the influence of traffic accessibility, the service domain of urban parks in northwest China is obviously smaller than that in eastern and southern China. Even within the service radius of urban parks, affected by the accessibility of traffic, there will be the situation that urban parks cannot be effectively covered. In view of the unreasonable layout of urban parks in Yuhang district, the following suggestions are put forward: the spatial layout of disaster prevention parks should be balanced layout considering accessibility factors; the space layout pattern of park green space nested with each other; Establish linkage mechanism of urban green space.
